ABSTRACT ALTHOUGH the inheritance of resistance1 in wheat (_Triticum aestivum_ L.) to stem rust (_Puccinia graminis_ Pers. f. sp. _tritici_ Eriks. & E. Henn.) is fairly well understood,
most efforts to elucidate the biochemical mechanism involved have been unsuccessful. Biochemical studies of plant diseases involving rusts and other obligate parasites2 have contributed to
knowledge of biochemical symptomatology, but no chemical changes have been correlated with the action of specific genes for resistance. Future advances it seemed, would depend on a reliable
test to facilitate such correlations, and so we have developed a bioassay with the necessary specificity, which detects the presence of metabolites involved in the expression of the
resistance. We have thus been able to demonstrate a gene-specific RNA that seems to be directly responsible for initiating the resistant reaction in wheat against stem rust. A preliminary
report of some of these findings has been presented3. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS OPTIONS
