黄瓜霜霉病及寄主抗性机制研究进展

Cucumber downy mildew and the mechanisms of host resistance: a review

摘要:

在黄瓜生产中，由古巴假霜霉菌（Pseudoperonospora cubensis）引起的霜霉病危害严重，影响叶、茎和花序生长发育，导致黄瓜产量及品质降低。通过对黄瓜霜霉病的病原菌检测和防御途径、影响及调控因素、抗病原菌候选基因发掘、蛋白质组和基因组分析、黄瓜霜霉病QTL连锁标记开发及其抗病育种等多方面的最新进展进行综述，以期为今后进一步揭示黄瓜乃至农作物对霜霉病的抗性机制研究提供借鉴和参考。

Abstract:

The cultivation and production of cucumber are seriously affected by downy mildew caused by Pseudoperonospora cubensis. Downy mildew damages leaves, stems and inflorescences, and then reduces the yield and quality of cucumber. This review summarized the research advances in cucumber downy mildew, including pathogen detection and defense pathways, regulatory factors, mining of pathogens-resistant candidate genes, proteomic and genomic analysis, and development of QTL remarks. This review may facilitate clarifying the resistance mechanisms of cucumber to downy mildew.
