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

在北半球潮湿条件下，疫霉根腐病导致土壤覆盆子人工林数量迅速下降，也大大降低了基质覆盆子的生产寿命，带来了负面的环境后果。基于植物的抗性是唯一的前进道路，并且存在有限的材料，可以持续抵抗感染，很少或没有症状产生。基因技术的发展为鉴定在植物与病原体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。抗性和易感品种在基因表达水平上的反应以及病原体对不同表型的反应将确定基因标记并允许制定控制策略。

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.
