Using molecular techniques, Agricultural Research Service (ARS) and collaborating scientists have shown how the subversion of a single gene in wheat by two fungal foes triggers a kind of celular suicide in the grain crop's leaves. Fortunately, the team has also developed DNA molecular markers that can be used to rapidly screen commercial cultivars for the gene, Tsn1, so it can be eliminated by selective breeding. This, in turn, would deprive the fungi of their primary means of killing off...

CSIRO researchers have identified wheat and barley lines resistant to Crown Rot "“ a disease that costs Australian wheat and barley farmers $79 million in lost yield every year. Crown Rot, which is a chronic problem throughout the Australian wheat belt, is caused by the fungus Fusarium. Dr Chunji Liu and his CSIRO Plant Industry team in Brisbane are using sophisticated screening methods to scan over 2400 wheat lines and 1000 barley lines from around the world to find the ones resistant...

The U.S. Agriculture Department said winter and spring wheat crops had caught up with their five-year averages as the winter wheat harvest gets under way. Ninety-five percent of the winter wheat crop has headed out, compared to an historic average of 97 percent by this week of the year. Ninety-nine percent of the spring wheat crop has emerged, compared to a five-year average of 100 percent, In addition, 68 percent of the winter wheat crop is in fair to excellent condition. Last year during...

Progress in the spring wheat crop remains far behind its historic average, the U.S. Department of Agriculture said Monday. Although spring wheat in Washington and South Dakota are close to five-year averages, the nation's crop in total is at 67 percent emergence against a five-year average of 90 percent for this time of year, the weekly crop reports said. Seventy-seven percent of the winter wheat crop has been harvested, compared to a five-year average of 81 percent for this week of the...

In a paper published today in the prestigious journal Science, scientists from CSIRO Plant Industry, the University of Zurich and the International Maize and Wheat Improvement Center have identified a wheat gene sequence which provides protection against leaf rust, stripe rust and powdery mildew. "Genetic disease resistance is highly desirable in plants as it is more environmentally friendly and profitable than strategies like spraying pesticides," says a senior principal research scientist...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
