植物通过一种中心昼夜节律调节器实现免疫应答的时序

交流:通过cca1 时间上控制防御基因能区分他们是参与基础还是r基因介导的抗性

植物对活病原体的主要免疫机制是电阻-基因介导的防御应答的结构被认为是共享广谱基础防御的组件然而,其潜在的分子机制大部分是未知的

交流:从而建立良种明显不同抗性机制之间的内在联系

1、theprincipal immunemechanism against biotrophic pathogens in plants is theresistance (r)-gene-mediateddefence1. it was proposedto sharecomponents w潜水ith the broad-spectrum basal defence machinery2. however,theunderlying molecular mechanism is largely unknown.

建议:植物中对活体寄生病原菌免疫机制的原理是抗性基因介导的抗性反应曾经认为它与广谱基础抗性机制共享组件

专业名词:r 为抗性基因, biotrophic, 为活体寄生

建议:这里我们报道参与r基因介导的针对拟南芥上霜霉病的新的基因得鉴定及通过生物钟相关基因cca1对它们的调控

建议:一个中心生物钟调控子决定植物免疫反应时机

交流:从而允许植物能够预期在正常情况下分散孢子之前,根据接收到的不潜水同病原菌侵染信号来决定免疫反应的时间

3、surprisingly,we found that these new defence genes areundercircadian control bycca1, allowing plants to ‘anticipate’ infection at dawn when thepathogen normally disperses the spores and time immune responsesaccording tothe perception of different pathogenic signals upon infection.t潜水旅游攻略emporal controlof the defence genes by cca1 differentiates their involvement inbasal andr-gene-mediateddefence. our study has revealed a key functional link betweenthe circadianclock and plant immunity.

timing of plant immune responses by a central circadian regulator

令人惊讶的是,我们发现,这些新的防卫基因通过cca1执行生物钟调控,让潜水运动介绍植物能够在一被感染时,根据感知到的不同病原信号,在病原体孢子散开和免疫应答前抵御感染f防御基因的时间控制通过(有无)cca1区分他们是参与基础防御和r基因介导的防御我们的研究揭示了一个关键的生物钟和植物免疫功能之间的联系

在这里,我们将介绍一个新基因cca1的识别,它参与拟南芥中电阻-基因介导的抗霜霉病防御,以及通过昼夜节律调节器实现调控基于这些基因突变株的表型的数值集群显示,程序性细胞死亡(pcd)是防御的主要贡献者突变株的r基因介导的pcd在基础防御中也有缺陷,这两个不同的防御机制之间相互联系

掰了好久,终于

2、 here wereport theidentification of novel gen潜水运动协会es involved in r-gene-mediatedresistance againstdowny mildew in arabidopsis and theirregulatory control by the circadianregulator, circadian clock-associated 1(cca1). numerical clustering based onphenotypes of these gene mutants revealedthat programmed cell death (pcd) isthe major contributor to resistanc潜水俱乐部e.mutants compromised in ther-gene-mediatedpcd were also defective in basal resistance, establishing aninterconnectionbetween these two distinct defence mechanisms.
