摘要:

病原菌的侵染激发植物大量防御响应基因的表达, 其中转录因子在协调庞大的抗病防御网络中发挥重要作用。灰葡萄孢菌(Botrytis cinerea)是最具破坏力的死体营养型病原真菌之一, 在农业生产上造成严重的经济损失。文章综述了ERF(Ethylene response factors)、WRKY、MYB等家族中参与灰霉病防御反应的转录因子的功能研究进展。转录因子通过复杂的mRNA或蛋白水平的互作方式构成了精细的调控网络, 以激活下游防卫基因的表达, 从而诱导抗病反应。一部分转录因子是协调不同激素信号通路交叉响应的重要节点和调节器, 将植物抵御不同类型病原菌的分子机制联系起来。对这类转录因子的研究将为研究植物其他病原菌防御机制提供线索, 另外深入理解抗病机制将有助于研究者在作物改良和保护中更高效地利用抗病基因。

Abstract:

A large number of defense genes are activated in plants when responding to pathogen infection. Furthermore, transcription factors are suggested to play important roles in regulating huge defense network in plants. The necrotrophic fungus Botrytis cinerea is one of the most destructive pathogens which could result in massive economic losses in the agriculture. Our review summarized the study results of members from transcription factor ERF, WRKY and MYB families which function in resistance of Botrytis cinerea in Arabidopsis thaliana. The transcription factors come into more elaborate regulation network through interacting with target genes at mRNA or protein levels aiming at activating expression of defense genes which lead to resistance against the fungus. Some transcriptional factors were discovered to be the main nodes and regulators in different phytohormones crosstalk, illustrating and connecting the molecular mechanisms of plants against different types of pathogens. Study on the transcription factor mentioned above, provides us clues for the study of other plant pathogen defense mechanism. Further understanding of disease mechanisms will help researchers to utilize the resis-tance genes in crop improvement and protection practice.
