它不仅对植物系统获得抗性(systemic acquired resistance,SAR)和诱导系统抗性(induced systemic resistance, ISR)起核心调控作用,而且是植物基础抗性(basic resistance)以及由抗病基因(resistance gene,R)决定的抗性的重要调控因子.氧化突发(oxidative burst)造成的强还原势导致NPR1蛋白还原成单体,以及NPR1单体在细胞核内的...
Pathogenesis-related gene expression in rice is correlated withdevelopmentally controlledXa21-mediated resistance againstXanthomonas oryzaepv.oryzae Disease resistance mediated by the resistance gene Xa21 is developmentally controlled in rice. We examined the relationship between Pathogenesis Related (P... G Po...

line, that over-expressed the tobacco class 5 pathogenesis-related (PR) gene for osmotin, was tested for altered transcriptional regulation of other PR genes which could account for the increased resistance to pathogens observed in this PR5 gene transformant. Transcripts encoding PR proteins were ...
When expressed in Arabidopsis npr1 mutants, BnNPR1 restored salicylic acid-dependent expression of the marker gene PR-1 and enhanced basal defense as well as systemic acquired resistance against a virulent strain of the bacterial pathogen Pseudomonas syringae. Expression of Arabidopsis NPR1 or over ...
