#Gene keeps wheat from sprouting on the stalk A new way to keep high humidity from damaging wheat crops could save farmers millions of dollars
#To beat stem rust, wheat crops get new gene University of California Davis rightoriginal Studyposted by Pat Bailey-UC Davis on July 30 2013uc DAVIS (US)# Scientists
have found a gene in wild wheat that could make commercial wheat varieties resistant to a new strain of stem rust.
By transferring this gene to commercial wheat varieties wheat breeders will have a distinct advantage in controlling the epidemic the researchers say.
since 1999 threatening important wheat production areas of the world#says co-author Jorge Dubcovsky a wheat geneticist at University of California Davis and a Howard hughes medical institute investigator.#
About 90 percent of the wheat varieties grown worldwide are susceptible to Ug99. Previous resistance genes that had proven effective for fighting the disease for 50 years are ineffective against this new race.
Scientists are now looking for new sources of resistance to protect the global wheat crop which millions of people depend on for food.
They then inserted the gene into a wheat variety that is susceptible to the diseases engineering a resistance to Ug99.#
and perform poorly when applied to polyploid species such as bread wheat (Triticum aestivum L) . which has multiple sets of chromosomes.
This disease is responsible for devastating bread wheat crops and has developed'Warrior'strains capable of infecting individuals previously believed to have tolerance."
and will tap into a Kansas wheat variety repository that dates back to the 1900s in hopes of finding a variety perhaps one that fell out of favour among commercial farmers that might already be low in reactivity for celiac sufferers.
Queensland grain growers have for many years produced wheat varieties classified as rime hard wheatbecause these were suited to the production of good-quality bread. he precise reason for the difference in the quality of the rime hard wheathas long been a mystery,
Professor Henry said. owever new wheat varieties must retain the essential quality characteristics of wheat. heat varieties are assessed normally for bread-making quality by conducting a baking test. his is only possible late in the breeding process
Professor Henry and his colleagues are eager to produce new premium wheat varieties. he good news is that premium wheats attract better prices so this discovery potentially means more dollars for Australian farmers.
AAFI scientists expect to exploit the bread-quality gene by developing improved wheat varieties using speed-breeding technologies that allow multiple generations of different varieties to be grown quickly
