摘要 植物干细胞是植物胚后发育形成各种组织和器官的细胞来源

和信号调控中心, 其调控机理是植物学研究的重要内容。过去20多年

在模式植物拟南芥中发现了多个干细胞调控因子, 但这些因子间如何相

互作用, 尤其是不同调控通路间如何整合是未来植物学研究需要解决的

关键问题。该文简要介绍了近期以WUSCHEL-RELA TED

HOMEOBOX (WOX)家族蛋白为中心开展的有关植物干细胞调控因子

间相互作用的一些新的研究进展, 并对未来该研究领域的发展进行了展

望。

Abstract Stem cells in plants are the ultimate source of cells

and also the signaling centre of the postembryonic development

of various tissues and organs. Their regulation is a key area in

plant science research. Studies in the model plant Arabidopsis in

the past two decades have discovered many key regulators of

plant stem cells, but how these factors interact, in particular how

the different regulatory pathways integrate is a key question for

future plant science studies. In this article, we briefly summarized

some recent progresses in studying the interactions of plant stem

cell regulators, with WUSCHEL-RELATED HOMEOBOX (WOX)

proteins at the center of focus, and discuss the possible

directions for future research in this area.

命力, 是因为其体内终生保留着不同类型的干细胞[2]。这些干细胞位于
