拟南芥(Arabidopsis thaliana)EXA1缺失会导致exa1-2突变体植株PR基因表达上调,对病原菌的抗性提高。该研究通过克隆甘蓝型油菜(Brassica napus)中的BnaEXA1,并将其在拟南芥e...展开更多 拟南芥(Arabidopsis thaliana)EXA1缺失会导致exa1-2突变体植株PR基因表达上调,对病原菌的抗性提高。该研究通过克隆甘蓝型油菜(Brassica napus)中的BnaEXA1,并将其在拟南芥exa1-2突变体中异源超表达,发现BnaEXA1超表达不仅可恢复突变体的表型,而且显著降低突变体中PR1和PR2基因的表达量,导致其对核盘菌(Sclerotinia sclerotiorum)和卵菌H.a.Noco2易感,表明BnaEXA1调控植物的基础抗性。收起

Loss function of EXA1 in Arabidopsis thaliana has been shown to increase PR gene expression and enhance resistance to pathogens.Here,we cloned BnaEXA1 in Brassica napus and ectopically overexpressed in A.thaliana exa1-2 mutant.We found that overexpressed BnaEXA1 not onl...MORE Loss function of EXA1 in Arabidopsis thaliana has been shown to increase PR gene expression and enhance resistance to pathogens.Here,we cloned BnaEXA1 in Brassica napus and ectopically overexpressed in A.thaliana exa1-2 mutant.We found that overexpressed BnaEXA1 not only restored the morphological defects of the exa1-2 m...
