摘要

了解物种形成的分子基础是进化生物学的首要目标。合子后生殖隔离的形成导致杂交功能障碍,从而减少不同种群之间的基因流动,这对物种形成至关重要。利用各种先进的方法,包括染色体替换、杂交渗入和转录组学、群体基因组学和实验进化,科学家们揭示了真菌王国中涉及合子后屏障的多种机制。这些结果阐明了真菌物种形成的独特和一般特征。本文综述了真菌中Dobzhansky-Muller不相容、杀手减数分裂驱动、染色体重排和抗重组对合子后生殖分离的影响。我们还讨论了不同生殖隔离机制背后可能的进化力量,以及在红皇后假说和物种形成的表观遗传分化下进化军备竞赛的潜在作用。

Enforcement of Postzygotic Species Boundaries in the Fungal Kingdom.

Understanding the molecular basis of speciation is a primary goal in evolutionary biology. The formation of the postzygotic reproductive isolation that causes hybrid dysfunction, thereby reducing gene flow between diverging populations, is crucial for speciation. Using various advanced approaches, including chromosome replacement, hybrid introgression and transcriptomics, population genomics, and experimental evolution, scientists have revealed multiple mechanisms involved in postzygotic barriers in the fungal kingdom. These results illuminate both unique and general features of fungal speciation. Our review summarizes experiments on fungi exploring how Dobzhansky-Muller incompatibility, killer meiotic drive, chromosome rearrangements, and antirecombination contribute to postzygotic reproductive isolation. We also discuss possible evolutionary forces underlying different reproductive isolation mechanisms and the potential roles of the evolutionary arms race under the Red Queen hypothesis and epigenetic divergence in speciation.

期刊介绍: Microbiology and Molecular Biology Reviews (MMBR), a journal that explores the significance and interrelationships of recent discoveries in various microbiology fields, publishes review articles that help both specialists and nonspecialists understand and apply the latest findings in their own research. MMBR covers a wide range of topics in microbiology, including microbial ecology, evolution, parasitology, biotechnology, and immunology. The journal caters to scientists with diverse interests in all areas of microbial science and encompasses viruses, bacteria, archaea, fungi, unicellular eukaryotes, and microbial parasites. MMBR primarily publishes authoritative and critical reviews that push the boundaries of knowledge, appealing to both specialists and generalists. The journal often includes descriptive figures and tables to enhance understanding. Indexed/Abstracted in various databases such as Agricola, BIOSIS Previews, CAB Abstracts, Cambridge Scientific Abstracts, Chemical Abstracts Service, Current Contents- Life Sciences, EMBASE, Food Science and Technology Abstracts, Illustrata, MEDLINE, Science Citation Index Expanded (Web of Science), Summon, and Scopus, among others.
