摘　要：

植物维管系统形成与分化包含着贯穿植物生长发育全过程的一系列细胞分裂与分化事件。这些事件的发生和发展过 程受到很多遗传和其他内源因子的调控。对维管系统形成及其调控的认识近年来获得了较大的进展。研究表明植物激素、 转录因子、短肽信号分子和 microRNA 等在植物维管系统建成中发挥重要调控作用。

Abstract:

The formation of plant vascular system involves a set of cell-programed events including cells division, cell fate determination and differentiation, which occurs through the entire life of plant development. In recent years significant progresses have been achieved in discovery of endogenous genetic and epigenetic signal molecules and circuits which play key roles in regulation of these events. Plant hormones, transcription factors, short signal peptides and microRNAs are involved in the formation of plant vascular system and its regulation.

Key words: xylem; phloem; cambium; plant hormones; transcription factors; short signal peptides; microRNA
