摘　　要：叶脉能够运输营养物质和水分,同时还为植物叶片提供机械支撑力,以维持正常的形态结构,从而有利于其生理功能的正常发挥。水稻侧脉的数量直接与叶片宽度成正比,叶片的合适宽度、长度以及直立度都影响其光合效率。因此,对水稻叶脉微管束系统的形态发育以及分子机理研究就显得相当重要。综述了近年有关水稻叶脉发育的细胞以及分子机制的研究进展,以期为研究者提供参考。Apart from transportation of nutrients and water, veins on leaves directly provide a mechanical support for blades in maintaining proper morphological architecture, thus exert normal physiological function. The width of leaf is positively correlative to the number of leaf vein in rice. Furthermore, the leaf width, length and erect index determine the plant photosynthetic efficiency. As a consequence, it is very significant to uncover the functional mechanism of vascular tissue in rice growth and development. This review mainly focuses on current findings about cytological and molecular mechanism of vascular development in rice, which expected to provide reference for researchers.
