Using genomics technologies to determine the mechanism of resistance to phytophthora root rot in raspberry for future breeding applications to raspberry and other crops

在条件潮湿的北半球，疫霉根腐病正在导致在土壤中种植的树莓种植园迅速减少，并极大地缩短了在基质中种植的树莓的生产寿命，对环境造成了负面影响。基于植物的抗性是唯一的出路，存在的材料有限，能够持续抵抗感染，产生的症状很少或没有症状。基于基因的技术的发展为鉴定在植物-病原菌相互作用中起重要作用的基因、确定抗性机制和开发包括育种在内的新的保护策略提供了机会。抗性和感病品种如何在基因表达水平上做出反应，以及病原菌如何对不同的表型做出反应，将识别基因标记并开发控制策略。

In the Northern Hemisphere with damper conditions, Phytophthora root rot is causing a rapid decline in raspberry plantations grown in soil and also greatly decreasing the life span of production of raspberries grown in substrate with negative environmental consequenses. Plant based resistance is the only way forward and limited material exists that consistently withstands infection with little/no symptom production. The development of gene based techniques offers an opportunity to identify genes that have a significant role in this plant-pathogen interaction to determine the mechanisms of resistance and develop novel strategies of protection including breeding. How both resistant and susceptible varieties respond at the level of gene expression and how the pathogen responds to the differing phenotypes will identify gene markers and allow strategies for control to be developed.
