植物与多种真菌相互作用，从病原体到有益的内生菌。真菌的致病和有益的生活方式通常是分开和独立研究的，因此，导致植物相关真菌生活方式转变的遗传基础方面尚未得到普遍解决。蛭毛菌属包括一组高度多样化的病原体，它们在广泛的植物宿主中感染并引起炭疽病。另一方面，在逆境条件下，一些蛭毛属植物作为有益的内生菌，促进植物生长。因此，具有不同感染策略的多种毛菌的存在为探索区分植物相关真菌的致病和有益生活方式的分子基础提供了合适的模型系统。本章回顾了最近与致病性和有益炭疽菌相关的分子基础研究，并讨论了基于比较基因组学和植物转录组分析结果的可能的生活方式决定的分子基础。
Plants interact with diverse fungal species, ranging from pathogens to beneficial endophytes. The pathogenic and beneficial lifestyles of fungi have often been studied separately and independently, so the aspects of genetic basis that contribute to lifestyle transitions in plant-associated fungi have not been generally addressed. TheColletotrichumgenus comprises a highly diverse group of pathogens that infect and cause anthracnose diseases in a wide range of plant hosts. On the other hand, some of theColletotrichumspecies act as beneficial endophytes and promote plant growth under conditions of stress. The presence of diverseColletotrichumspecies with contrasting infection strategies thus provides a suitable model system in which to explore the molecular basis for discriminating pathogenic and beneficial lifestyles of plant-associated fungi. This chapter reviews recent molecular-based research related to pathogenic and beneficialColletotrichumspecies and discusses the possible molecular basis underlying the lifestyle determination, based on the results of comparative genomics andin plantatranscriptome analysis.
