In the August 2011 issue of the Journal of Bacteriology, a team of researchers led by DOE JGI’s Patrick Chain at Los Alamos National Laboratory focused on a microbe that can help or harm as the case may be. Ochrobactrum anthropi thrives in a variety of habitats including polluted soil, plants and even higher mammals…. [Read More]
Septoria typically infects young seedlings that have recently emerged, creating lesions, and spreading to the higher leaves. It can affect yield and quality, Goodwin said. Control methods are typically fungicide sprays, he noted. Igor Grigoriev, of the U.S. Department of Energy’s Joint Genome Institute in Walnut Creek, Calif., has been sequencing the genomes of other… [Read More]
Enzymes often break down plant cell walls and begin removing nutrients, leading to the plant’s death. M. graminicola, however, enters the plant through stomata, small pores in the surface of leaves that allow for exchange of gases and water. Goodwin said the fungus seems to lay dormant between plant cells, avoiding detection. It later infects… [Read More]
The pathogen that causes the disease, Mycosphaerella graminicola, has a long “silent period,” a latent stage during which it takes nutrition from the living plant and evades the host plant’s natural defenses. Scientists previously did not have a good understanding of how the organism infects wheat, or how the wheat plant itself resists the pathogen…. [Read More]
SCIENTISTS have cracked the genetic code of septoria tritici – the most important foliar disease of wheat in the UK – and in doing so have gained an insight into how the disease is able to evade wheat’s natural defences. The researchers, who were funded by the BBSRC and others, hope the study, which reveals… [Read More]
