摘　　要：气孔的密度及分布模式受到植物基因组编码信息、激素信号以及环境刺激的复杂调控,调控的模式包括配体-受体识别、蛋白翻译后修饰、转录水平变化等一系列复杂的生物学过程。近期的研究表明,成熟叶片感知的生物和非生物信号以长距离信号转导的模式调控新生叶片的气孔发育。本文在梳理与气孔发育相关的细胞内源性机制的基础上,综述了目前已知的调控气孔发育的系统性信号,并对这些信号进行长距离转导的可能模式进行了总结和展望。The density and distribution pattern of plant stomata are subject to complex regulation by genome-encoded information,hormonal signals and environmental stimuli.The modes of regulation include multiple complex biological processes encompassing ligand-receptor recognition,post-translational modification of proteins,and changes in transcript levels.Recent studies have also shown that both biotic and abiotic signals sensed by mature leaves can modulate stomatal development of nascent leaves in a long-distance signal transduction manner.In addition to summarization of the endogenous cellular mechanisms underlying stomatal development,this paper also reviews the identified systemic signals and discusses the possible modes of long-distance transduction of these signals.
