Bryophytes occupy a basal position in the monophyletic evolution of land plants and have a life cycle in which the gametophyte generation dominates over the sporophyte generation, offering a significant advantage in conducting genetics. Owing to its low genetic redundancy and the availability of an array of versatile molecular tools, including efficient genome editing, the liverwort Marchantia polymorpha has become a model organism of choice that provides clues to the mechanisms underlying eco-evo-devo biology in plants. Recent analyses of developmental mutants have revealed that key genes in developmental processes are functionally well conserved in plants, despite their morphological differences, and that lineage-specific evolution occurred by neo/subfunctionalization of common ancestral genes. We suggest that M. polymorpha is an excellent platform to uncover the conserved and diversified mechanisms underlying land plant development. Expected final online publication date for the Annual Review of Plant Biology, Volume 72 is May 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

多形马钱子的发展和分子遗传学。

苔藓植物在陆地植物的单系统进化中占据着基础地位，并具有一个生命周期，其中配子体世代比孢子体世代占优势，在进行遗传学方面具有显着优势。由于其低遗传冗余性和包括有效的基因组编辑在内的一系列通用分子工具的可用性，多形艾蒿Marchantia polymorpha已成为一种典范生物，为植物中生态-进化-生物学的基础机制提供了线索。对发育突变体的最新分析表明，尽管发育过程中的关键基因在形态上存在差异，但它们在功能上在植物中的保守性很好，并且谱系特异性进化是通过共同祖先基因的新/亚功能化而发生的。我们建议M。多形体是揭示陆地植物发展的保守和多样化机制的绝佳平台。《植物生物学年度评论》第72卷的最终最终在线发布日期为2021年5月。有关修订的估算，请参见http://www.annualreviews.org/page/journal/pubdates。
