摘要
藓类的蒴齿生于藓类植物孢蒴口部,由蒴周层3层细胞或细胞壁发育而成,结构较为复杂。其主要功能是主导和保护藓类孢子的散发,同时也是分类和判定藓类系统发育地位的一个重要依据。藓类蒴齿的结构多样性、功能多样性和分子生物学层面的研究目前在国内还较薄弱。该文对近年来国内外有关藓类蒴齿的发育、结构和功能的相关研究进展进行了综述。
Moss peristome is located at the mouth of the capsule with complex structure, and it is derived from three layers of cell or cell wall of amphithecium. The function of peristome is mainly to dominate and protect spores dispersing, and also serves as an important basis for determining the phylogenetic status and classification of mosses. At present, the structural diversity, functional diversity and molecular biology of moss peristome are the weaknesses in China. This advances reviews the study of development, structure and function in moss peristome at home and abroad in recent years.
