Transcriptome dynamics Associated with Resistance and Susceptibility against Fusarium Head Blight in Four Wheat Genotypes
We report differentially expressed genes in four wheat genotypes, Nyubai, Wuhan 1 and their progeny line HC374, shaw associated with resistance and susceptibility against Fusarium Head Blight (FHB). Our result indicates an early up-regulation of LRR-RKs distinct between susceptible and resistant genotypes; subsequently, different sets of genes associated with defense response were up-regulated. Differences in expression profiles among the resistant genotypes indicate genotype specific defense mechanisms. This study also showed a greater resemblance in transcriptomics of HC374 to Nyubai, consistent with their sharing of two type II FHB resistant QTLs on 3BS and 5AS, than to Wuhan 1 which carries one QTL on 2DL in common with HC374. Overall design: The four genotypes were subjected to challenge by the pathogenic fungus Fusarium graminearum and water mock treatment as a control
