The genomics era has ushered in exciting possibilities to examine the genetic bases that undergird the characteristic features of and other plant pathogens. In this review, we provide historical perspectives on some of the salient biological characteristics of , 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 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 .
基因组学时代带来了令人兴奋的可能性，可以研究支撑 和其他植物病原体特征的遗传基础。在这篇综述中，我们提供了关于 的一些显著生物学特征的历史观点，包括其形态、小菌核形成、宿主范围、病症、维管束小生境、繁殖和种群结构。总结了该病原体的万花筒式种群结构，包括病原体的不同菌系、落叶和非落叶表型、营养体亲和群和无性种群。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 和相关物种内的种群分化提供了见解。本文还强调了当前的挑战，并提出了一些未来的种群基因组学研究建议，这将有助于增进我们对 种群分化的理解。
