摘　　要：再生是植物适应外界伤害的重要策略之一,也是植物生物学研究的重要领域。通过对种子植物的研究,在新生组织器官的发生机理以及生长素和细胞分裂素对于再生的调控作用等方面已经取得了多项引人瞩目的成果。苔藓是最原始的高等植物,小立碗藓(Physcomitrella patens)属于藓类植物的葫芦藓科,可以很方便地开展遗传操作,通过同源重组以及CRISPR的方法达到基因敲入和敲除的目的。由于小立碗藓不需要外源施加植物生长调节物质就能发生再生,非常利于从细胞水平上开展再生的起始调控研究。本文对于近年来苔藓植物的再生特点和重要研究进展进行了介绍。Regeneration is one of the important strategies for plants to adapt to external injuries as well as an important biological question for plant science.Many remarkable results have been achieved in seed plants,mainly involving the mechanism of new tissues and organs regeneration and the regulation of auxin,cytokinin and other plant hormones in those processes.Bryophytes are the most primitive higher plants.It is easy to carry out genetic modification and achieve the goal of gene knock-in and knockout by homologous recombination in Physcomitrella patens which belongs to Funariaceae.Since the regeneration of Physcomitrella can occur without exogenous hormones,it is very convenient to study the regulation of regeneration at the cell level.In recent years,some important research results have been published on the regeneration of Physcomitrella.In this paper,the regeneration characteristics and important research progress of Physcomitrella are introduced.
