Research Progress in Sex Determination Mechanism of Flowering Plants
开花植物的性别表型具有高度的多样性和可塑性特征,包括雌雄同体、雌雄同株、雌全同株、雄全同株、雌雄异株、雌全异株、雄全异株等,从进化生物学的角度看,均由雌雄同体的祖先演化而来.不同开花植物的性别决定机制也复杂多样,主要包括双因子突变模型、单因子突变模型、性染色体遗传机制和表观遗传调控机制等.人工驯化可改变植物的性别表型,此外还有部分变性植物.植物性别分化过程易受到外界环境因素影响,有些植物个体在生活史的不同阶段其性别还会发生改变,具有可塑性.文中结合开花植物性别决定机制最新研究进展,从遗传和进化角度介绍开花植物多样性别表型产生的理论机制并进行研究展望.
The sex phenotype of flowering plants is characterized by diversity and plasticity,including hermaphroditism,monoecy,gynomonoecy,andromonoecy,dioecy,gynodioecy,and androdioecy,all of which have evolved from hermaphroditic ancestors.The mechanisms underlying sex determination in flowering plants are highly complex and varied,such as two-factor model,single-factor model,X∶A model and epigenetic regulation.Artificial domestication can alter plant sexual phenotypes,and some species even display sex-changing capabilities.Sex differentiation process in plants is highly susceptible to external environmental factors.For some individual plants,sex may undergo dynamic transition across different stages of their life cycle,demonstrating a remarkable degree of sexual plasticity.This paper presents the latest research advances on sex determination in flowering plants and discusses the theoretical mechanism underlying the generation of diverse sexual phenotypes from both genetic and evolutionary perspectives.
