摘要
基因的重复(duplication)及其功能的多样性(diversification)为生物体新的形态进化提供了原材料。MADS-box基因在植物(特别是被子植物)的进化过程中发生了大规模的基因重复事件而形成一个多基因家族。MADS-box基因家族的不同成员在植物生长发育过程中起着非常重要的作用,在调控开花时间、决定花分生组织和花器官特征以及调控根、叶、胚珠及果实的发育中起着广泛的作用。探讨MADS-box基因家族的进化历史有助于深入了解基因重复及随后其功能分化的过程和机制。本文综述了MADS-box基因家族基因重复及其功能分化式样的研究进展。
Gene duplication and diversification can provide the raw material for discovering morphological changes in organisms. The MADS-box genes encoding a family of transcription factors have undergone extensive gene duplication events and subsequent functional divergence during evolution. In flowering plants, MADS-box genes control diverse developmental processes in organs ranging from roots to flowers and fruit development. Studies on the evolutionary history of the MADS-box gene family have highlighted the dynamic fates of the duplicate genes and can provide evidence to better understand the mechanisms behind the evolution of plant morphology. This paper reviews the progress of gene duplication and subsequent functional diversification in the MADS-box gene family.
