Gain of plant disease resistance by plant cell homeostasis and anti-microbial second metabolite

在本研究中，我们试图从植物病理学、植物细胞生理学和植物分子生物学的角度来理解植物新型抗病的机制，而不是传统的植物抗病，即寄主特异性抗性和非寄主抗性。植物抗病性的两个新方面是：1)植物细胞的内稳态功能，即维持植物细胞自然状态的功能；2)植物抗微生物第二代谢物的生物合成能力，用于植物防御。我们已经发现Cdc27B作为细胞周期调节因子参与烟草的植物抗病，以及水稻的三萜皂苷生物合成基因。

In this study, we tried to make sense the mechanism of novel plant disease resistance unlike to conventional plant disease resistance, that are host-specific resistance and non-host resistance, using not only plant pathology, but also plant cell physiology and plant molecular biology. A couple of the novel plant disease resistance is 1) plant cell homeostasis, that is the function for keeping natural state of plant cell going, and 2) the faculty for biosynthesis of anti-microbial second metabolite for plant defense. We have revealed that Cdc27B as cell cycle regulator are involved in plant disease resistance in tobacco, and the genes for triterpene-saponin biosynthesis in rice.
