Transcriptome analysis of a wheat NIL pair carrying FHB resistant and susceptible alleles


ABSTRACT: In this study, we used the Affymetrix wheat GeneChip to examine the transcript accumulation in a near-isogenic line pair carrying resistant and susceptible alleles at the wheat Fhb1 locus. The objectives of this study were: (1) to identify the overall response in wheat to F. graminearum infection; (2) to identify key genes involved in FHB resistance/susceptibility pathways in wheat; (3) to compare the transcript profiles of wheat and barley during F. graminearum infection; and (4) to examine the relationship between transcript accumulation, disease severity, fungal biomass and trichothecene accumulation in wheat. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Seungho Cho.

Fusarium head blight (FHB), caused primarily by Fusarium graminearum, decreases grain yield and quality in wheat and barley. Disease severity, deoxynivalenol (DON), fungal biomass, and transcript accumulation were examined in a wheat near-isogenic line pair carrying either the resistant or susceptible allele for the chromosome 3BS FHB-resistance quantitative trait locus (Fhb1). Fhb1 restricts spread of disease symptoms but does not provide resistance to initial infection or initial DON accumulat  ...[more]
