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 fungi in the same class.
“We think we will be able to derive those features that make them pathogens,” Grigoriev said.
