World's food supply got a little more plentiful: Resistance gene found against ug99 wheat stem rust pathogen

June 27, 2013 ? The world's food supply got a little more plentiful thanks to a scientific breakthrough.

Eduard Akhunov, associate professor of plant pathology at Kansas State University, and his colleague, Jorge Dubcovsky from the University of California-Davis, led a research project that identified a gene that gives wheat plants resistance to one of the most deadly races of the wheat stem rust pathogen -- called Ug99 -- that was first discovered in Uganda in 1999. The discovery may help scientists develop new wheat varieties and strategies that protect the world's food crops against the wheat stem rust pathogen that is spreading from Africa to the breadbaskets of Asia and can cause significant crop losses.

Other Kansas State University researchers include Harold Trick, professor of plant pathology; Andres Salcedo, doctoral candidate in genetics from Mexico; and Cyrille Saintenac, a postdoctoral research associate currently working at the Institut National de la Recherche Agronomique in France. The project was funded by the U.S. Department of Agriculture and Borlaug Global Rust Initiative.

The team's study, "Identification of Wheat Gene Sr35 that Confers Resistance to Ug99 Stem Rust Race Group," appears in the journal Science.

It identifies the stem rust resistance gene named Sr35, and appears alongside a study from an Australian group that identifies another effective resistance gene called Sr33.

"This gene, Sr35, functions as a key component of plants' immune system," Akhunov said. "It recognizes the invading pathogen and triggers a response in the plant to fight the disease."

Wheat stem rust is caused by a fungal pathogen. According to Akhunov, since the 1950s wheat breeders have been able to develop wheat varieties that are largely resistant to this pathogen. However, the emergence of strain Ug99 in Uganda in 1999 devastated crops and has spread to Kenya, Ethiopia, Sudan and Yemen, though has yet to reach the U.S.

"Until that point, wheat breeders had two or three genes that were so efficient against stem rust for decades that this disease wasn't the biggest concern," Akhunov said. "However, the discovery of the Ug99 race of pathogen showed that changes in the virulence of existing pathogen races can become a huge problem."

As a first line of defense, wheat breeders and researchers began looking for resistance genes among those that had already been discovered in the existing germplasm repositories, he said.

"The Sr35 gene was one of those genes that was discovered in einkorn wheat grown in Turkey," Akhunov said. "Until now, however, we did not know what kind of gene confers resistance to Ug99 in this wheat accession."

To identify the resistance gene Sr35, the team turned to einkorn wheat that is known to be resistant to the Ug99 fungal strain. Einkorn wheat has limited economic value and is cultivated in small areas of the Mediterranean region. It has been replaced by higher yielding pasta and bread wheat varieties.

Researchers spent nearly four years trying to identify the location of the Sr35 gene in the wheat genome, which contains nearly two times more genetic information than the human genome.

Once the researchers narrowed the list of candidate genes, they used two complimentary approaches to find the Sr35 gene. First, they chemically mutagenized the resistant accession of wheat to identify plants that become susceptible to the stem rust pathogen.

"It was a matter of knocking out each candidate gene until we found the one that made a plant susceptible," Akhunov said. "It was a tedious process and took a lot of time, but it was worth the effort."

Next, researchers isolated the candidate gene and used biotechnical approaches to develop transgenic plants that carried the Sr35 gene and showed resistance to the Ug99 race of stem rust.

Now that the resistance gene has been found, Akhunov and colleagues are looking at what proteins are transferred by the fungus into the wheat plants and recognized by the protein encoded by the Sr35 gene. This will help researchers to better understand the molecular mechanisms behind infection and develop new approaches for controlling this devastating pathogen.

Climate tug of war disrupting Australian atmospheric circulation patterns

June 26, 2013 ? Further evidence of climate change shifting atmospheric circulation in the southern Australian-New Zealand region has been identified in a new study.

The study, in the Nature journal Scientific Reports, demonstrates that mid-latitude high pressure zones (30^oS-45^oS) are being pushed further into the Southern Ocean by rising global temperatures associated with greenhouse warming. This is despite more frequent occurrences of strong El Ni?os in recent decades, which should have drawn the high pressure zones in the opposite direction toward the equator.

"What we are seeing," says study lead author, Mr Guojian Wang "is a 'tug of war' between stronger El Ni?os driving the winds north and the greenhouse gas-warming effect driving the winds south."

Mr Wang, said the result confirms the robustness of the Southern Hemisphere circulation changes over the past three to four decades as the global temperature rose, "so much so that it overode the influence from strong El Ni?os during this period."

Study co-author, Dr Wenju Cai said the most conspicuous change is a rising sea level pressure in the mid-latitude bands and a decreasing sea level pressure over the Southern high latitudes (55^o-70^oS), a pattern referred to as the Southern Annular Mode. The changing pressures indicate a poleward or southward expansion of the tropical and subtropical atmospheric zones.

In turn, this indicates that over the long-term, there is a relationship between a rising global mean temperature and an upward trend of the Southern Annular Mode.

"The research reinforces our past work that climate change is altering Southern Hemisphere circulation and increases our confidence in this conclusion," Dr Cai said.

Dr Cai has previously reported on changes in atmospheric circulation that have been shifting and strengthening the Pacific Ocean winds poleward and in turn strengthening the ocean circulation, pushing the East Australian Current further south down the Australian coast.

He said during El Ni?o, the warmer ocean releases heat to the atmosphere and global average temperatures increase. At the same time, warm ocean surface temperatures along the equator cause the tropical and subtropical atmospheric belts to move toward the equator, generating a 'negative' phase of the Southern Annular Mode.

"On year-to-year time scales, higher global temperatures are associated with a negative phase of the Mode but over the past 35 years, when El Ni?o has been strong and conducive to a negative trend, we are seeing an opposite trend with the circulation systems moving southward impacting on regional climate," he said.

The project was funded through the Australian Climate Change Science Program.

Russia, U.S. fail to set up Syria peace talks

By Oliver Holmes and Tom Miles

BEIRUT/GENEVA (Reuters) - Talks between the United States and Russia to set up a Syrian peace conference produced no deal on Tuesday, with the powers on either side of the two-year civil war failing to agree when it should be held or who would be invited.

Saudi Foreign Minister Prince Saud al-Faisal accused the Syrian government of "genocide" and described the involvement in the conflict of foreign militias backed by Iran as "the most dangerous development".

Washington and Moscow announced plans for the peace conference last month, but their relations have since deteriorated rapidly, as momentum on the battlefield has swung in favor of President Bashar al-Assad.

Washington decided this month to provide military aid to the rebels fighting Assad, while Moscow refused to drop its support for the Syrian leader it has continued to arm.

After five hours of talks in Geneva sponsored by the United Nations, Russian Deputy Foreign Minister Gennady Gatilov said there was still no agreement over whether Assad's ally Iran should be allowed to attend the conference, or who would represent the Syrian opposition.

The United States and Western European powers have joined Arab countries and Turkey in supporting the mainly Sunni Muslim rebels. Russia and Iran support Assad, who has made gains in recent weeks with the help of thousands of fighters from the Iranian-backed Lebanese Shi'ite militia Hezbollah.

U.S. Secretary of State John Kerry and Russian Foreign Minister Sergei Lavrov will meet next week, and further talks on the conference are expected to follow, a U.N. statement said.

In Damascus, Assad's forces fired mortars and shells at Zamalka and Irbin, just east of the government-held city centre, in an assault backed by air strikes, opposition activists said.

Rebels who grabbed footholds in Damascus nearly a year ago say they now face an advancing Syrian military buoyed by support from Hezbollah.

If the insurgents are driven from the capital's eastern suburbs, they would lose supply routes and suffer a heavy blow in their drive to end four decades of Assad family rule.

In Jeddah, Prince Saud repeated Saudi Arabia's call for the rebels to be armed. "Syria is facing a double-edged attack. It is facing genocide by the government and an invasion from outside the government," he told a news conference with Kerry. "(It) is facing a massive flow of weapons to aid and abet that invasion and that genocide. This must end."

The Saudi foreign minister attacked Iranian involvement. "The most dangerous development is the foreign participation, represented by Hezbollah and other militias supported by the forces of the Iranian Revolutionary Guard," he said.

Saudi Arabia, a Sunni state which views Shi'ite Iran as its arch-rival, has increased aid to Syrian rebels in recent months, supplying anti-aircraft missiles among other weapons.

Security in Syria's neighbors Iraq and Lebanon, where the conflict has aggravated Sunni-Shi'ite tensions, has crumbled.

Suicide bombers killed eight people north of Baghdad on Tuesday, a day after 39 people died when 10 car bombs exploded in the capital. Violence has spiraled in Iraq since April.

"GETTING OUT OF HAND"

In Lebanon, clashes between the Lebanese army and gunmen led by an anti-Hezbollah Sunni cleric engulfed the southern port of Sidon on Sunday and Monday. At least 40 people were killed, including 18 soldiers, security sources said.

Sectarian hatred has even flared in Sunni-majority Egypt, where a crowd attacked and killed five Shi'ites on Sunday.

Lakhdar Brahimi, the U.N.-Arab League mediator, urged the United States and Russia to help "contain this situation that is getting out of hand, not only in Syria but also in the region".

Speaking in Geneva before the talks with U.S. and Russian officials, Brahimi said he doubted that the Syria peace conference could take place next month, citing disarray among Assad's political opponents.

More than 93,000 people have been killed in Syria since peaceful protests erupted in March 2011. Assad's violent response helped to provoke what is now a civil war that has driven nearly 1.7 million refugees into neighbouring countries.

Outgunned rebels are looking to Western and Arab nations to help them to reverse Assad's gains. But although the United States announced unspecified military aid this month, it is unclear whether this can shift the balance against the Syrian leader and his allies.

Kerry wants to ensure aid to the rebels is properly coordinated, partly out of concern that weapons could end up in the hands of Islamist militants who are prominent in their ranks. "Our goal is very clear, we cannot let this be a wider war, we cannot let this contribute to more bloodshed and prolongation of the agony of the people of Syria," he said.

Three planets in habitable zone of nearby star: Gliese 667c reexamined

June 25, 2013 ? A team of astronomers has combined new observations of Gliese 667C with existing data from HARPS at ESO's 3.6-metre telescope in Chile, to reveal a system with at least six planets. A record-breaking three of these planets are super-Earths lying in the zone around the star where liquid water could exist, making them possible candidates for the presence of life. This is the first system found with a fully packed habitable zone.

Gliese 667C is a very well-studied star. Just over one third of the mass of the Sun, it is part of a triple star system known as Gliese 667 (also referred to as GJ 667), 22 light-years away in the constellation of Scorpius (The Scorpion). This is quite close to us -- within the Sun's neighbourhood -- and much closer than the star systems investigated using telescopes such as the planet-hunting Kepler space telescope.

Previous studies of Gliese 667C had found that the star hosts three planets with one of them in the habitable zone. Now, a team of astronomers led by Guillem Anglada-Escud? of the University of G?ttingen, Germany and Mikko Tuomi of the University of Hertfordshire, UK, has reexamined the system. They have added new HARPS observations, along with data from ESO's Very Large Telescope, the W.M. Keck Observatory and the Magellan Telescopes, to the already existing picture [1]. The team has found evidence for up to seven planets around the star [2].

These planets orbit the third fainter star of a triple star system. Viewed from one of these newly found planets the two other suns would look like a pair of very bright stars visible in the daytime and at night they would provide as much illumination as the full Moon. The new planets completely fill up the habitable zone of Gliese 667C, as there are no more stable orbits in which a planet could exist at the right distance to it.

"We knew that the star had three planets from previous studies, so we wanted to see whether there were any more," says Tuomi. "By adding some new observations and revisiting existing data we were able to confirm these three and confidently reveal several more. Finding three low-mass planets in the star's habitable zone is very exciting!"

Three of these planets are confirmed to be super-Earths -- planets more massive than Earth, but less massive than planets like Uranus or Neptune -- that are within their star's habitable zone, a thin shell around a star in which water may be present in liquid form if conditions are right. This is the first time that three such planets have been spotted orbiting in this zone in the same system [3].

"The number of potentially habitable planets in our galaxy is much greater if we can expect to find several of them around each low-mass star -- instead of looking at ten stars to look for a single potentially habitable planet, we now know we can look at just one star and find several of them," adds co-author Rory Barnes (University of Washington, USA).

Compact systems around Sun-like stars have been found to be abundant in the Milky Way. Around such stars, planets orbiting close to the parent star are very hot and are unlikely to be habitable. But this is not true for cooler and dimmer stars such as Gliese 667C. In this case the habitable zone lies entirely within an orbit the size of Mercury's, much closer in than for our Sun. The Gliese 667C system is the first example of a system where such a low-mass star is seen to host several potentially rocky planets in the habitable zone.

The ESO scientist responsible for HARPS, Gaspare Lo Curto, remarks: "This exciting result was largely made possible by the power of HARPS and its associated software and it also underlines the value of the ESO archive. It is very good to also see several independent research groups exploiting this unique instrument and achieving the ultimate precision."

And Anglada-Escud? concludes: "These new results highlight how valuable it can be to re-analyse data in this way and combine results from different teams on different telescopes."

Notes

[1] The team used data from the UVES spectrograph on ESO's Very Large Telescope in Chile (to determine the properties of the star accurately), the Carnegie Planet Finder Spectrograph (PFS) at the 6.5-metre Magellan II Telescope at the Las Campanas Observatory in Chile, the HIRES spectrograph mounted on the Keck 10-metre telescope on Mauna Kea, Hawaii as well as extensive previous data from HARPS (the High Accuracy Radial velocity Planet Searcher) at ESO's 3.6-metre telescope in Chile (gathered through the M dwarf programme led by X. Bonfils and M. Mayor 2003-2010.

[2] The team looked at radial velocity data of Gliese 667C, a method often used to hunt for exoplanets. They performed a robust Bayesian statistical analysis to spot the signals of the planets. The first five signals are very confident, while the sixth is tentative, and seventh more tentative still. This system consists of three habitable-zone super-Earths, two hot planets further in, and two cooler planets further out. The planets in the habitable zone and those closer to the star are expected to always have the same side facing the star, so that their day and year will be the same lengths, with one side in perpetual sunshine and the other always night.

[3] In the Solar System Venus orbits close to the inner edge of the habitable zone and Mars close to the outer edge. The precise extent of the habitable zone depends on many factors.

Canucks hire fired Rangers coach John Tortorella

VANCOUVER, British Columbia (AP) ? The Vancouver Canucks hired John Tortorella to be their new coach on Tuesday.

Tortorella was recently fired by the New York Rangers after they lost to the Boston Bruins in the second round of the playoffs in five games.

The 55-year-old Tortorella replaces former Canucks coach Alain Vigneault, who took over for him as the Rangers coach last week.

Tortorella has been an NHL coach since 2001. He led the Tampa Bay Lightning to the Stanley Cup championship in 2004.

The Boston native said during a news conference on Tuesday that he has longed to coach a team in Canada.

"To be involved with this, I couldn't be more excited," Tortorella said. "It's always something I thought about and wanted the opportunity."

As coach of the Rangers the past five seasons, Tortorella led New York to the playoffs three times.

"John has coached championship teams and is passionate about winning," Canucks general manager Mike Gillis said in a statement. "He has a proven ability to bring the best out of his players and we believe he has all of the qualities to bring our team success."

Tortorella has reached the playoffs eight times and won the Jack Adams Award as NHL coach of the year in 2004. Known for his fiery and often abrasive style, he was let go four days after the Rangers' season ended against the Eastern Conference champion Bruins.

"I know how important that part of the job is here," Tortorella said of dealing with the media. "When you lose your job, you crawl into a hole a little bit, you reassess yourself, you try to learn, and I have certainly gone through that process.

"Have I made mistakes? Absolutely. I make my own bed in this type of situation with the perception of myself in the media. But I know how important it is with this job here, especially in this city and this province."

However, the demanding coach said he won't change his stance on player accountability, and said everyone including scoring stars Henrik and Daniel Sedin will have a lot asked of them ? including killing penalties and blocking shots.

"We have a really good leadership group ... but we have not won the Stanley Cup," he said. "There's going to be more asked of (the players), and that starts from the twins right on down."

Tortorella was an assistant with the Rangers in the 1999-2000 season and took over for John Muckler as coach for the final four games. Tortorella later spent seven seasons as coach of the Lightning before returning to the Rangers in February 2009 after head coach Tom Renney was fired.

Vigneault was let go after the Canucks were eliminated in the first round of the playoffs for the second straight year. He guided the Canucks to a berth in the Stanley Cup Final in 2011 and helped the team win two Presidents' trophies and six Northwest Division titles.

Tortorella, the career leader in wins by a U.S.-born coach with 410, served as an assistant for the American team that won silver at the 2010 Vancouver Olympics. He also handled head coaching duties for Team USA at the 2008 world championship and served as an assistant coach at the event in 2005.

Syria death toll tops 100,000, rebels lose border town

By Dominic Evans and Oliver Holmes

BEIRUT (Reuters) - Syrian President Bashar al-Assad's forces have retaken a town on the Lebanese border as they press an offensive against rebels in a conflict that has now cost more than 100,000 lives, activists said on Wednesday.

The army took full control of Tel Kalakh, driving out insurgents and ending an unofficial truce under which it had allowed a small rebel presence to remain for several months.

The fall of Tel Kalakh, two miles from the border with Lebanon, marks another gain for Assad after the capture of the rebel stronghold of Qusair this month, and consolidates his control around the central city of Homs, which links Damascus to his Alawite heartland overlooking the Mediterranean coast.

Like Qusair, Tel Kalakh was used by rebels in the early stages of the conflict as a transit point for weapons and fighters smuggled into Syria to join the fight against Assad.

Pro-Assad websites showed video footage of soldiers patrolling the town in armored cars and on foot.

"Terrorist groups infiltrated and terrorized the local people," an army officer said in the video. "In response to the request of the local people, the army entered Tel Kalakh to cleanse the area and restore security."

The British-based Syrian Observatory for Human Rights, a pro-opposition monitoring group, said rebels left the town on Tuesday, retreating towards the nearby Crusader fort of Crac des Chevaliers. Three rebels were killed as the army moved in.

Six months ago, Assad's opponents were challenging the president's grip on parts of Damascus, but are now under fierce military pressure there, while their supply lines from neighboring Jordan and Lebanon have steadily been choked off.

DEATH TOLL TOPS 100,000

In response to Assad's gains, achieved with the support of Lebanon's pro-Iranian Hezbollah fighters who spearheaded the assault on Qusair, Western and Arab nations pledged at the weekend to send urgent military aid to the rebels.

Hezbollah's involvement has highlighted the increasingly sectarian dynamic in the Syrian conflict. Hezbollah and Tehran back Assad, whose Alawite minority is an offshoot of Shi'ite Islam, while Sunni Muslim states such as Turkey, Saudi Arabia and Qatar have stepped up support for the mainly Sunni rebels.

Radical Sunni militants from abroad, some of them linked to al Qaeda, are also coming in to fight alongside the rebels.

Jordan's King Abdullah said the war could ignite conflict across the Middle East unless global powers helped to convene peace talks soon.

"It has become clear to all that the Syrian crisis may extend from being a civil war to a regional and sectarian conflict...the extent of which is unknown," the monarch told Asharq al-Awsat newspaper in an interview.

"It is time for a more serious Arab and international coordination to stop the deterioration of the Syrian crisis. The situation cannot wait any longer," he added.

But prospects for proposed "Geneva 2" peace talks look bleak. Talks on Tuesday between the United States and Russia, which support opposing sides in Syria, produced no agreement on who should attend the conference or when it should be held.

Saudi Arabia, which views Shi'ite Iran as its arch-rival, has stepped up aid to Syrian rebels in recent months, supplying anti-aircraft missiles among other weapons.

"Syria is facing a double-edged attack. It is facing genocide by the government and an invasion from outside the government," Saudi Foreign Minister Prince Saud al-Faisal said on Tuesday. "(It) is facing a massive flow of weapons to aid and abet that invasion and that genocide. This must end."

The Observatory, which monitors violence through a network of security and medical sources in Syria, said the death toll from two years of conflict had risen above 100,000 - making it by far the deadliest of the uprisings to have swept the region.

It said the figure included 18,000 rebel fighters and about 40,000 soldiers and pro-Assad militiamen. But the true number of combatants killed was likely to be double that due to both sides' secrecy in reporting casualties, it said.

In addition to the casualties, it said, 10,000 people had been detained by pro-Assad forces and 2,500 soldiers and loyalist militiamen had been captured by the rebels.

The United Nations has put the death toll from the 27-month-old conflict at 93,000 by the end of April.

The violence has fuelled instability and sectarian tensions in Syria's neighbors, particularly Iraq and Lebanon.

At least 40 people were killed this week in the Lebanese city of Sidon in clashes between the army and gunmen loyal to a firebrand Sunni cleric who backs the Syrian rebels and has urged Sunnis to challenge Hezbollah's military might in Lebanon.

On Wednesday, unidentified attackers stabbed at least five passengers on a bus carrying Syrians in Beirut, security sources said. None of the victims was seriously wounded, they said.

Screen middle-aged adults for hepatitis C: panel

By Genevra Pittman

NEW YORK (Reuters Health) - Adults born between 1945 and 1965 should be screened once for hepatitis C, a government-backed panel recommended today.

The statement, from the U.S. Preventive Services Task Force (USPSTF), is stronger than draft recommendations published in November, which advised doctors to "consider offering screening" to members of the Baby Boom generation (see Reuters Health story of Nov 26, 2012 here: http://reut.rs/WsjtVA).

The final recommendations - which also call for screening people at high risk of hepatitis C, such as injection drug users - were published Monday in the Annals of Internal Medicine.

The "moderate" net benefit of screening was supported by studies showing people with the chronic infection who take medicine and have a very low level of the virus in their blood - known as a sustained viral response - are at lower risk of liver cirrhosis, cancer and death.

"New evidence came out since the draft recommendation, which gave us greater confidence in the linkage between a sustained viral response and important outcomes," Dr. Albert Siu, co-vice chair of the task force, told Reuters Health.

The USPSTF also found that tools used to assess liver health and guide treatment are becoming safer, and that the harms of hepatitis C medication, including headaches and flu-like symptoms, are "small."

Hepatitis C is treated with a combination regimen of ribavirin and peginterferon alfa (also commonly known as Pegasys and Peg-Intron), to which newer drugs - known as boceprevir (Victrelis) and telaprevir (Incivek) - can be added.

Siu, from the Icahn School of Medicine at Mount Sinai in New York, said the rate of hepatitis C among people born in 1945 through 1965 is about 4 percent, compared to about 1 percent among other Americans.

That difference is likely due to "risky behavior that was engaged in during this time," he said.

Many people living with hepatitis C are not aware they have the condition, the task force said, and may go years without showing symptoms.

Stanford University's Jeremy Goldhaber-Fiebert, who worked on one of the studies that influenced the updated recommendation, told Reuters Health that screening middle-aged adults seems to be effective and cost-effective - but that there are other considerations as well.

"It's really important that when screening is rolled out, that we ensure that those people who screen positive have access to timely, high-quality treatment," he said.
