苔藓植物，包括苔类、藓类和角苔类，是配子体优势的陆地植物，它们起源于一个共同的祖先，并从孢子体优势的维管植物中独立进化而来。植物激素生长素已被证明在苔藓植物单倍体中起多效性作用。药理学和化学研究鉴定了苔藓植物组织中生长素的保守分子、失活形式和生长素的转运。最近的基因组和分子生物学研究表明，陆地植物中生长素的合成、失活、运输和信号传导的成分及其功能具有深度保守性。低遗传冗余模式苔藓植物使独特的分析，这是阐明生长素信号通路的设计原则。本文就生长素在苔藓植物中的生理作用及生长素调控基因表达和发育的机制作一综述。
Bryophytes, including liverworts, mosses, and hornworts, are gametophyte-dominant land plants that are derived from a common ancestor and underwent independent evolution from the sporophyte-dominant vascular plants since their divergence. The plant hormone auxin has been shown to play pleiotropic roles in the haploid bodies of bryophytes. Pharmacological and chemical studies identified conserved auxin molecules, their inactivated forms, and auxin transport in bryophyte tissues. Recent genomic and molecular biological studies show deep conservation of components and their functions in auxin biosynthesis, inactivation, transport, and signaling in land plants. Low genetic redundancy in model bryophytes enable unique assays, which are elucidating the design principles of the auxin signaling pathway. In this article, the physiological roles of auxin and regulatory mechanisms of gene expression and development by auxin in Bryophyta are reviewed.
