摘要: The induction by cytokinin stress and ethylene of nine different tobacco mosaic virus-inducible mRNA classes (termed A-I) encoding pathogenesis-related (PR) proteins was studied. induced levels were compared to basal in healthy plants grown tissue culture a greenhouse. Cytokinin found induce subsets the mRNAs, indicating that is not primary inducing signal cytokinin-stressed shoots. mRNAs F, H G basic hydrolytic enzymes chitinase, β-1,3-glucanase equivalent PR-1, respectively, be expressed at high roots plants. D, I B acidic equivalents proved present low These results indicate genes isoforms are differentially regulated.
