摘要
植物叶片背-腹轴极性建立是叶片形态建成的重要过程之一。ASYMMETRIC LEAVES1/ASYMMETRIC LEAVES2(AS1/AS2)是植物叶片发育中背-腹面极性关键的转录因子,直接或间接与多个蛋白或miRNAs相互协作,共同调控植物叶片发育与形成过程。本文主要综述了拟南芥、大白菜等植物AS1/AS2保守结构特征及其参与叶片侧生器官形成的启动、叶片背腹极性建立的调控等功能,总结了AS2参与植物生长激素的运输及分布、植物育性及花器官发育、植物抗病反应等生物学功能,并对今后AS1/AS2调控植物发育机制中的具体研究方向进行了展望。本文对AS1/AS2在植物发育过程功能的总结与展望,将为深入揭示AS1/AS2生物学功能的分子机制提供思路,为叶类蔬菜的新种质资源创新提供重要的理论依据。
The establishment of Adaxial-Abaxial polarity of plant leaves is one of the important processes in leaf morphogenesis.ASYMMETRIC LEAVES1/ASYMMETRIC LEAVES2(AS1/AS2)are key transcription factors that modulate the Adaxial-Abaxial polarity in plant leaf development.These factors directly or indirectly cooperate with multiple proteins or miRNAs to co-regulating the development and formation of plant leaves.This review summarized the conserved structural features of AS1/AS2 in Arabidopsis thaliana and Chinese cabbage,and their regulatory functions involved in the initiation of leaf lateral organ formation and the establishment of leaf Adaxial-Abaxial polarity.Then,the specific research directions of AS1/AS2 regulation mechanisms of plant development in the future is also prospected.The summary and prospect of AS1/AS2 functions in plant development in this paper will provide ideas for further revealing the molecular mechanism of AS1/AS2 biological functions,and provide an important theoretical basis for the innovation of new germplasm resources of leafy vegetables.
