Abstract

Yeasts, usually defined as unicellular fungi, occur in various fungal lineages. Hence, they are not a taxonomic unit, but rather represent a fungal lifestyle shared by several unrelated lineages. Although the discovery of new yeast species occurs at an increasing speed, at the current rate it will likely take hundreds of years, if ever, before they will all be documented. Many parts of the earth, including many threatened habitats, remain unsampled for yeasts and many others are only superficially studied. Cold habitats, such as glaciers, are home to a specific community of cold-adapted yeasts, and, hence, there is some urgency to study such environments at locations where they might disappear soon due to anthropogenic climate change. The same is true for yeast communities in various natural forests that are impacted by deforestation and forest conversion. Many countries of the so-called Global South have not been sampled for yeasts, despite their economic promise. However, extensive research activity in Asia, especially China, has yielded many taxonomic novelties. Comparative genomics studies have demonstrated the presence of yeast species with a hybrid origin, many of them isolated from clinical or industrial environments. DNA-metabarcoding studies have demonstrated the prevalence, and in some cases dominance, of yeast species in soils and marine waters worldwide, including some surprising distributions, such as the unexpected and likely common presence of Malassezia yeasts in marine habitats.

酵母多样性发现趋势
酵母,通常被定义为单细胞真菌,出现在各种真菌谱系中。因此,它们不是一个分类单位,而是代表了几个不相关谱系共享的真菌生活方式。尽管新的酵母菌种类的发现正以越来越快的速度发生,但按照目前的速度,它们可能需要数百年的时间才能全部被记录下来。地球上的许多地方,包括许多受到威胁的栖息地,仍然没有对酵母进行采样,而其他许多地方只进行了肤浅的研究。寒冷的栖息地,如冰川,是适应寒冷的特定酵母群落的家园,因此,迫切需要在这些环境可能很快因人为气候变化而消失的地方进行研究。受到森林砍伐和森林转换影响的各种天然林中的酵母群落也是如此。许多所谓的“全球南方”国家尽管经济前景光明,但还没有进行酵母取样。然而,在亚洲,特别是中国,广泛的研究活动产生了许多新的分类。比较基因组学研究已经证明存在具有杂交起源的酵母物种,其中许多是从临床或工业环境中分离出来的。dna元条形码研究表明,酵母菌在世界范围内的土壤和海水中普遍存在,在某些情况下占主导地位,包括一些令人惊讶的分布,例如在海洋栖息地中意想不到且可能普遍存在马拉色菌。

期刊介绍: Fungal Diversity, the official journal of the Kunming Institute of Botany of the Chinese Academy of Sciences, is an international, peer-reviewed journal covering all aspects of mycology. It prioritizes papers on biodiversity, systematic, and molecular phylogeny. While it welcomes novel research and review articles, authors aiming to publish checklists are advised to seek regional journals, and the introduction of new species and genera should generally be supported by molecular data. Published articles undergo peer review and are accessible online first with a permanent DOI, making them citable as the official Version of Record according to NISO RP-8-2008 standards. Any necessary corrections after online publication require the publication of an Erratum.
