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.

大丽花黄萎病种群基因组学时代来临之际的关键见解和研究前景。
基因组学时代为研究大丽花黄萎病和其他植物病原体的遗传基础带来了令人兴奋的可能性。在这篇综述中,我们从历史的角度介绍了大丽花的一些显著生物学特性,包括其形态、微核形成、宿主范围、疾病症状、血管生态位、繁殖和种群结构。综述了该病原菌千变万化的种群结构,包括不同的病原菌小种、落叶型和非落叶型表型、营养相容性类群和无性系群体。在可能的情况下,我们将特征差异置于比较和功能基因组学分析的背景下,这些分析为大丽花及其相关物种的种群差异提供了见解。强调了当前的挑战以及一些建议的未来种群基因组学研究,这些研究将有助于促进我们对大丽花的种群差异的理解。
