The downy mildew pathogen, Pseudoperonospora cubensis, which infects plant species in the family Cucurbitaceae, has undergone major changes during the last decade. Disease severity and epidemics are far more destructive than previously reported, and new genotypes, races, pathotypes, and mating types of the pathogen have been discovered in populations from around the globe as a result of the resurgence of the disease. Consequently, disease control through host plant resistance and fungicide applications has become more complex. This resurgence of P. cubensis offers challenges to scientists in many research areas including pathogen biology, epidemiology and dispersal, population structure and population genetics, host preference, host-pathogen interactions and gene expression, genetic host plant resistance, inheritance of host and fungicide resistance, and chemical disease control. This review serves to summarize the current status of this major pathogen and to guide future management and research efforts within this pathosystem.
霜霉病病原菌古巴假霜霉菌（Pseudoperonospora cubensis）可侵染葫芦科植物，在过去十年间发生了重大变化。病害严重程度和流行情况比之前报道的更具毁灭性，由于该病害的再度流行，在全球各地的病原菌种群中发现了新的基因型、生理小种、致病型和交配型。因此，通过寄主植物抗性和施用杀菌剂来控制病害变得更加复杂。古巴假霜霉菌的再度流行给许多研究领域的科学家带来了挑战，这些领域包括病原菌生物学、流行病学与传播、种群结构与种群遗传学、寄主偏好、寄主-病原菌相互作用与基因表达、寄主植物的遗传抗性、寄主和杀菌剂抗性的遗传，以及化学病害防治。本综述旨在总结这种主要病原菌的现状，并指导该病害系统未来的管理和研究工作。
