Characterisation of interacting genes that condition avirulence and resistance between Phytophthora pathogens and soybean

大豆疫霉病原菌与大豆间毒力和抗性互作基因的特征分析。疫霉属植物病原体在澳大利亚和世界范围内造成严重的作物损失。寄主植物的抗性通常通过病原菌中无毒基因的突变来克服，从而产生有毒的新品种。我们将从大豆疫霉菌中克隆和鉴定控制毒力和无毒的基因，并分离与疫霉菌基因产物相互作用的大豆基因。对分子机制的理解将使现有的植物品种能够识别导致抗性或易感性的疫霉病原体，这将有助于大豆和其他作物植物持久抗病的新策略的发展。

Characterisation of interacting genes that condition avirulence and resistance between Phytophthora pathogens and soybean. Plant pathogens from the genus Phytophthora cause severe crop losses in Australia and worldwide. Resistance in host plants is frequently overcome by mutation of avirulence genes in the pathogen to create virulent new races. We will clone and characterise genes from Phytophthora sojae that control virulence and avirulence, and isolate soybean genes whose products interact with the Phytophthora gene products. An understanding of the molecular mechanisms than enable current plant varieties to recognise Phytophthora pathogens leading to resistance or susceptibility will assist the development of novel strategies for durable disease resistance in soybean and other crop plants.
