【摘要】 蔗糖转运蛋白是光合产物运输与分配调控网络中的重要节点,主要参与蔗糖从"源"到"库"的质外体运输,在蔗糖的感应、"源"器官装载、韧皮部长距离运输和"库"器官卸载中起重要作用。总结和分析了水稻蔗糖转运蛋白基因家族的组成、蛋白结构特点、表达与调控特性、生物学功能等方面的研究进展,在此基础上,提出了蔗糖转运蛋白基础理论和应用研究方面存在的不足及应予重视和加强的主要方向。更多还原

【Abstract】 Sucrose transporter is the most important regulatory protein in the photosynthate transport and distribution. It plays a key role in the sucrose apoplastic transport form"source"to"sink", mainly functions in sucrose induction, loading into "source"organs, long-distance transport through phloem, and unloading in the "sink"organs. The progresses in the composition of rice sucrose transporter gene family, characters of protein structure, expression and regulation characteristics and biological functions are summarized and analyzed. On this basis, the shortcomings of the basic theory and applied research in the sucrose transporter, and the main direction we should pay attention to strengthening were suggested.更多还原
