花粉蛋白质组学研究进展

花粉是高度退化的生物体（雄配子体），在植物有性生殖过程中具有重要作用。解析花粉发育、花粉-柱头识别、萌发和花粉管生长等细胞学过程的分子机制是当前研究的热点问题之一。近年来，应用高通量的蛋白质组学技术平台，对水稻、拟南芥和裸子植物花粉的蛋白质组学研究揭示了花粉中表达蛋白质的功能类群特征。花粉中参与细胞壁代谢、蛋白质代谢、细胞骨架动态和信号转导的蛋白质被高度代表，并且近1／4蛋白质有多个同工型。本文综述了花粉蛋白质组学的研究进展。

Research Advances on Pollen Proteomics

Pollen is a highly reduced organism that plays a great role in plant sexual reproduction as the male gametophyte. Much research has focused on the molecular mechanism of pollen development, the interaction with the pistil, germination, and pollen tube growth. In recent years, high-throughput proteomic approaches allowing for proteomic investigation of the pollen of rice, Arabidopsis and gymnosperms have led to characterization of a functional category of proteins expressed in pollen. Proteins involved in wall remodeling and metabolism, protein metabolism, cytoskeletal dynamics and signal transduction are highly represented in pollen, and 25% of proteins appear as multHsoforms. This paper gives an overview of recent pollen proteomic investigations.
