摘　要：

叶片近-远轴极性建成是一个重要的叶片发育过程。该过程与叶片光合作用等重要的生理过程密切相关, 受众多内外环境因子所调控。本文介绍了叶片近-远轴极性的特征及发育建成过程, 探讨了近轴极性基因、远轴极性基因、小RNA、YABBY家族基因、WOX家族基因和植物激素等在叶片近-远轴极性建成过程中的功能及相互关系, 总结了叶片近-远轴极性建成相关的基因网络调控系统, 并对今后叶片近-远轴极性建成的研究方向及应用前景提出了一些见解。

Abstract:

The establishment of leaf adaxial-abaxial polarity comprises one of the most important aspects of leaf development. Leaf polarity development is tightly related to a series of important physiological processes such as photosynthesis, and it is under the regulation of both extrinsic and intrinsic cues. In this review, the basic characteristics and developmental process of leaf adaxial-abaxial polarity were introduced, followed by the function of different abaxial genes, adaxial genes, small RNAs, YABBY genes, WOX genes, and plant hormones in leaf adaxial-abaxial polarity development. The interaction between different regulators and gene networks controlling leaf polarity development were also summerized. Based on all available information about leaf polarity development, the future direction of leaf adaxial-abaxial polarity development was brought forward in this review as well.
