Wheat powdery mildew is a disease of global importance that occurs across wide geographic area in the United States. A virulence survey Blumeria graminis f. sp. tritici, causal agent, was conducted by sampling 36 wheat fields 15 U.S. states years 2013 and 2014. Using hierarchical protocol, isolates were derived from three separated plants at each five sites within field order to assess spatial distribution pathotypes. In total, 1,017 those tested individually on single-gene differential...

Wheat powdery mildew, caused by Blumeria graminis f. sp. tritici, is managed in the United States with cultivar resistance and foliar fungicides. Despite high levels of fungicide sensitivity other cereal mildew populations, U.S. B. tritici has never been evaluated. Almost 400 isolates were collected from 15 states over 2 years phenotyped for to two widely used demethylation inhibitor (DMI) fungicides, tebuconazole prothioconazole. A large range both DMIs was observed, more insensitive...
Wheat powdery mildew, caused by Blumeria graminis f. sp. tritici, is managed primarily with cultivar resistance and foliar fungicides. Quinone outside inhibitors (QoIs), which target the mitochondrial cytochrome b (cytb) gene, are one of two main fungicide classes used on wheat. While European populations B. tritici widely insensitive to QoIs, largely because cytb mutation G143A, QoI sensitivity U.S. population had never been evaluated despite years use A total 381 isolates from 15 central...
Similar progressive leaf lesion phenotypes, named conring for "concentric ring," were identified in 10 independently derived maize lines. Complementation and mapping experiments indicated that the phenotype had same genetic basis each line - a single recessive gene located 1.1-Mb region on chromosome 2. Among 15 predicted genes this interval, Zm00001d003866 (subsequently renamed Conring or Cnr) insertions of four related 138 bp transposable element (TE) sequences at precisely site exon 4...
