Differential accumulation of translatable mRNA species during a specific host-pathogen interaction between Puccinia recondita tritici and Triticum aestivum

The time-course of mRNA induction in specific cultivar-race combinations was examined using a criss-cross interaction system consisting of nearly isogenic lines of wheat (Sinvalocho M.A. and Gamma 1R) and genetically related pathogenic races of leaf rust Puccinia recondita f. sp. tritici. Infection...

Summary:The time-course of mRNA induction in specific cultivar-race combinations was examined using a criss-cross interaction system consisting of nearly isogenic lines of wheat (Sinvalocho M.A. and Gamma 1R) and genetically related pathogenic races of leaf rust Puccinia recondita f. sp. tritici. Infection stimulated the differential accumulation of mRNA species, identified by in vitro translation, after only three days of inoculation with rust spores. Comparisons of different host-pathogen combinations showed polypeptide pattern changes likely to be associated with gene-for-gene relationships. At least two specific mRNAs which code for polypeptide bands of 34 and 24 kDa are associated with the compatible interaction mediated by genes A1/A2 from Gamma 1R wheat line and virulence gene p1/p2 of rust race F01. Comparisons made using a mutant clone of rust, which elicits an inverse criss-cross relationship with the same wheat lines, are consistent with the proposed specificity of the detected changes
