Abstract

Polyamines are involved not only in fundamental cellular processes such as growth, differentiation, and morphogenesis, but also in various environmental stresses. We demonstrated that spermidine, a polyamine, confers resistance to rice blast accompanied by the up-regulation of marker genes for the salicylic acid-mediated signaling pathway and and of phytoalexin biosynthesis genes and . This is the first report about the involvement of spermidine in rice disease resistance.

摘要

多胺不仅参与细胞的基本过程,如生长、分化和形态发生,还参与各种环境胁迫。我们证明,多胺亚精胺赋予水稻对稻瘟病的抗性,同时水杨酸介导的信号通路标记基因以及植物抗毒素生物合成基因上调。这是关于亚精胺参与水稻抗病性的首次报道。
