Abstract:
The genomics era has ushered in exciting possibilities to examine the genetic bases that undergird the characteristic features of Verticillium dahliae and other plant pathogens. In this review, we provide historical perspectives on some of the salient biological characteristics of V. dahliae, including its morphology, microsclerotia formation, host range, disease symptoms, vascular niche, reproduction, and population structure. The kaleidoscopic population structure of this pathogen is summarized, including different races of the pathogen, defoliating and nondefoliating phenotypes, vegetative compatibility groupings, and clonal populations. Where possible, we place the characteristic differences in the context of comparative and functional genomics analyses that have offered insights into population divergence within V. dahliae and the related species.Current challenges are highlighted along with some suggested future population genomics studies that will contribute to advancing our understanding of the population divergence in V. dahliae.
摘要:
基因组学时代带来了令人兴奋的可能性,可以检查构成黄萎病菌和其他植物病原体特征的遗传基础。在这次审查中,我们提供了关于大丽花弧菌的一些显著生物学特征的历史观点,包括它的形态,微菌核形成,主机范围,疾病症状,血管生态位,繁殖,和人口结构。总结了该病原体的万花筒种群结构,包括病原体的不同种族,落叶和非落叶表型,植物相容性分组,和克隆种群。在可能的情况下,我们将特征差异放在比较和功能基因组学分析的背景下,这些分析为大丽花弧菌和相关物种的种群差异提供了见解。当前的挑战以及一些建议的未来人口基因组学研究得到了强调,这将有助于提高我们对大丽花弧菌种群差异的理解。
