The invasion of the land by plants, or terrestrialization, was one of the most critical events in the history of the Earth. The evolution of land plants included significant transformations in body plans: the emergence of a multicellular diploid sporophyte, transition from gametophyte-dominant to sporophyte-dominant life histories, and development of many specialized tissues and organs, such as stomata, vascular tissues, roots, leaves, seeds, and flowers. Recent advances in molecular genetics in two model basal plants, bryophytes Physcomitrella patens and Marchantia polymorpha, have begun to provide answers to several key questions regarding land plant evolution. This paper discusses the evolution of the genes and regulatory mechanisms that helped drive such significant morphological innovations among land-based plants.
植物对陆地的入侵，即陆地化，是地球历史上最关键的事件之一。陆地植物的进化包括身体结构的重大转变：多细胞二倍体孢子体的出现、从配子体主导到孢子体主导的生活史转变，以及许多专门组织和器官的发育，如气孔、维管组织、根、叶、种子和花。两种模式基部植物苔藓植物小立碗藓和地钱的分子遗传学研究取得的最新进展，已开始为有关陆地植物进化的几个关键问题提供答案。本文讨论了有助于推动陆地植物发生如此重大形态创新的基因和调控机制的进化。
