摘要
烟霉菌属(Anthracoidea)包含 100 多个物种,主要寄生于莎草属(Carex)的宿主。Anthracoidea 属的物种主要分布在北半球的北方地区,许多物种分布在北极-高山地区。最近对主要寄主薹草属(Carex)的分类进行了重新整理,这质疑了目前对蚁属寄主关联的理解。该属许多物种的寄主特异性被认为相当广泛,寄主谱超过 10 种的情况很常见。这项研究的目的之一是了解寄主分类对Anthracoidea进化模式的潜在影响。此外,通过纳入更多的标本,我们利用分子数据澄清了半栉水母(Anthracoidea sempervirentis)的寄主特异性和物种划分,该物种在不同的薹草亚群中出现在不同的寄主物种上。Anthracoidea 的宿主定殖模式非常复杂,不同的薹草亚支系曾多次被独立定殖,而相关 Anthracoidea 种类的支系则经常发生在同一宿主支系的薹草种类上。以前认为寄生在不同薹草寄主上的半知母蚁(Anthracoidea sempervirentis)被证明是至少四个不同的物种,它们局限于个别寄主物种。描述并说明了三个新种,即阿尔卑斯山和喀尔巴阡山脉铁线蕨上的 Anthracoidea ferrugineae、阿尔卑斯山铁线蕨上的 A. firmae 和巴尔干半岛山区鸢尾上的 A. kitaibelianae。此外,还提供了对 Anthracoidea sempervirentis 的修订描述。修改后的半pervirentis Anthracoidea 包括两个支系,分别对应半蕨薹草(Carex sempervirens)中的两个支系。该研究表明,蚁属植物的宿主定殖比目前的宿主分类学所认为的要复杂得多。此外,将每个寄主物种的几个标本包括在内,会导致 Anthracoidea 内的多样性比以前假设的要高得多。引用:Kemler M, Denchev TT, Feige A, Denchev CM, Begerow D (2024).真菌植物寄生虫 Anthracoidea sempervirentis(Anthracoideaceae, Ustilaginales)的宿主特异性揭示了三个新种,并表明宿主植物 Carex sempervirens 有可能分裂。Fungal Systematics and Evolution 13: 91-110. doi: 10.3114/fuse.2024.13.04.
Host specificity in the fungal plant parasite Anthracoidea sempervirentis (Anthracoideaceae, Ustilaginales) reveals three new species and indicates a potential split in the host plant Carex sempervirens.
The smut fungal genus Anthracoidea contains more than 100 species that parasitize hosts predominantly in the sedge genus Carex. Anthracoidea species are mainly found in the boreal zones of the Northern Hemisphere and many species have an arctic-alpine distribution. Recent re-organization of the taxonomy of the main host genus Carex questions current understanding of host associations in Anthracoidea. Host specificity for many of the species in this genus is considered to be quite broad and a host spectrum of over 10 host species is common. One aim of the study is to understand the potential influence that host taxonomy has on the evolutionary patterns of Anthracoidea. Additionally, by including more specimens, we clarify host specificity and species delimitation in Anthracoidea sempervirentis, a prevalent species occurring on different host species in different Carex subgroups using molecular data. Host colonization patterns within Anthracoidea are complex, and different subclades of Carex have been colonized several times independently, whereas clades of related Anthracoidea species often occur on Carex species from the same host clade. Parasites previously thought to be Anthracoidea sempervirentis occurring on the different Carex host are shown to be at least four distinct species that are restricted to individual host species. Three new species, Anthracoidea ferrugineae on Carex ferruginea from the Alps and the Carpathians, A. firmae on Carex firma from the Alps, and A. kitaibelianae on Carex kitaibeliana from mountains in the Balkan Peninsula, are described and illustrated. An emended description of Anthracoidea sempervirentis is also provided. Anthracoidea sempervirentis in its emended circumscription consists of two clades that correspond to respective clades within Carex sempervirens. The study shows that host colonization in Anthracoidea is more complex than current host taxonomy suggests. Further, including several specimens per host species results in a much higher diversity within Anthracoidea than previously assumed.
