Enhanced salicylic acid biosynthesis contributes to increased resistance to biotrophic bacterial pathogen in Arabidopsis hybrids

Heterosis,the phenotypic superiority of a hybrid over its parents,has been demonstrated for many traits in Arabidopsis thaliana,but its effect on defense remains largely unexplored.Here,we show that hybrids between some A.thaliana accessions show increased resistance to the biotrophic bacterial path...Heterosis,the phenotypic superiority of a hybrid over its parents,has been demonstrated for many traits in Arabidopsis thaliana,but its effect on defense remains largely unexplored.Here,we show that hybrids between some A.thaliana accessions show increased resistance to the biotrophic bacterial path...中国细胞生物学学会植物器官发生专业委员会、中国植物学会植物生理及分子生物学专业委员会
