Project description:The assess the effect of AvrSr35 knock-out on host-pathogen interaction in the compatible host, we have performed time-course analysis of leaf transcriptomes obtained by infecting susceptible wheat cultivar Fielder with the wild type Puccinia graminis f.sp. tritici (Pgt) isolate 99KS76A-1 and its three mutants, M1, M4 and M7, that carry loss-of-function mutations in the AvrSr35 gene.
Project description:Puccinia graminis f. sp. tritici is the cause of wheat stem rust. A microarray was designed from genes predicted from the P. graminis f. sp. tritici genome assembly, and gene expression measured for four conditions which include wheat or barley infecting growth stages initiated by urediniospores. mRNA was prepared from fresh urediniospores, uredinospores germinated for 24 hr, wheat seedlings infected with urediniospores for 8 days, and barley seedlings infected with urediniospores for 8 days. The asexual uredinial infection cycle on wheat produces additional urediniospores, which can start new cycles of wheat infection and are readily spread by aerial transport. This expression data is further described in Duplessis et al, Obligate Biotrophy Features Unraveled by the Genomic Analysis of the Rust Fungi, Melampsora larici-populina and Puccinia graminis f. sp. tritici

Project description:We report the transcriptional analysis of the Blumeria graminis and Puccinia triticina biotrophic pathogen during their respective growth on Lr34 resistance and susceptible barley and wheat plants. No gene expression pattern has been observed suggesting that pathogen does not react to the presence of the resistance gene.
