中文摘要:

一氧化氮(没有) 并且氢过氧化物(H_2O_2 ) 被显示了重要表明参予几个生理的过程的规定的分子。特别地,他们由贡献正式就职防卫基因在植物抵抗有重要角色到病原体。这里,是否不并且 H_2O_2 参予抵抗回答 againstVerticillium dahliae 毒素(VD 毒素) ,他们 GSrgene 的表示上的效果被学习。结果不揭示那并且作为对 VD 毒素作出回应并且可以收敛由导致抵抗回答 synergistically 并且独立地工作的信号的一个复杂网络的部分生产的 H_2O_2are。GST 基因潜在地在 thecottonsuspension 房间涉及抵抗机制。不独立于 H2O2 导致 GST 基因的表示。H2O2 可以是在对 VD 毒素的抵抗回答的一个更多的有势力信号。

英文摘要:

Nitric oxide (NO) and hydrogen peroxide (H2O2) have been shown to be important signaling molecules that participate in the regulation of several physiological processes. In particular, they have significant role in plant resistance to pathogens by contributing to induction defense genes. Here, whether NO and H2O2 participate in the resistance responses against Verticillium dahliae toxins (VD-toxins) and their effects on the expression of GSTgene are studied. The results reveal that NO and H2O2 are produced as part of a complex network of signals that respond to VD-toxins and may converge to function both synergistically and independently by inducing resistant responses. GSTgene is potentially involved in the resistance mechanism in the cotton suspension cells. NO induces the expression of GSTgene independently of H2O2. H2O2 may be a more potent signal in the resistance responses against VD-toxins.
