Transcriptome profiling study has revealed molecular players in early
infection of Sclerotinia stem rot onsoybeans. The results of the study
conducted by researchers from the University of Illinois, Urbana, Ottawa
Research and Development Centre, USDA Agricultural Research Service are
published in/Genetics and Genomics of Resistance/.
Sclerotinia stem rot is caused by/Sclerotinia sclerotiorum/on soybeans.
The transcriptomes of two soybean genotypes and the pathogen were
simultaneously determined using RNA sequencing. A total of 594 geneswere
found to be significantly induced by/S. sclerotiorum/, and both soybean
hosts expressed genes linked to jasmonic acid, ethylene, oxidative
burst, and phenylpropanoids. About 36% of the differentially expressed
genes coded for genes associated with transcription factors,
ubiquitination, or general signaling transduction. No significant
differentially expressed genes were identified between genotypes,
suggesting that oxalic acid had no vital contributions to early disease
development.
