Rust fungi (Pucciniales, Basidiomycota) are obligate biotrophic pathogens that cause rust diseases in plants, inflicting severe damage to agricultural crops. Pucciniales possess the most complex life cycles known in fungi. These include an alternation of generations, the development of up to five different sporulating stages, and, for many species, the requirement of infecting two unrelated host plants during different parts of their life cycle, termed heteroecism. These fungi have been extensively studied in the past century through microscopy and inoculation studies, providing precise descriptions of their infection processes, although the molecular mechanisms underlying their unique biology are poorly understood. In this review, we cover recent genomic and life cycle transcriptomic studies in several heteroecious rust species, which provide insights into the genetic tool kits associated with host adaptation and virulence, opening new avenues for unraveling their unique evolution.

异性锈菌的宿主适应性和毒力
锈菌(Pucciniales, Basidiomycota)是专性生物营养病原体,可引起植物锈病,对农作物造成严重损害。Pucciniales 拥有真菌中已知的最复杂的生命周期。这些包括世代交替、多达五个不同孢子形成阶段的发展,以及对于许多物种而言,在其生命周期的不同部分感染两种不相关的寄主植物的要求,称为异源性。在过去的一个世纪中,通过显微镜和接种研究对这些真菌进行了广泛的研究,提供了对其感染过程的精确描述,尽管对其独特生物学的分子机制知之甚少。在这篇综述中,我们涵盖了几个异源锈菌物种的最新基因组和生命周期转录组学研究,
