摘　　要：根系作为植株唯一的地下器官,其生长状况对地上部分的生长发育以及产量的形成有直接影响,根生长受到抑制将严重制约水稻产量潜力进一步发挥。研究水稻根系生长发育的分子机制,对改良水稻根系结构,进而提高水稻产量,具有重要的理论和现实意义。本研究从细胞壁的结构与功能、纤维素的结构及生物合成、纤维素合酶基因以及其它纤维素合成相关基因等方面,综合阐述了纤维素合成相关基因调控水稻根系细胞壁形成及根系发育机制的研究进展,以期为深入了解水稻根系形成的分子机理和根系育种提供参考。The root system is the only und erground organ of the plant. The root condition directly affects the growth and development of the aboveground part and the formation of yield, which is the key factor that restricts the further development of rice yield potential. Studying the genetic mechanism of rice root growth and development has important theoretical and practical significance for improving rice root structure and increasing rice yield. In this paper, from the structure and function of cell wall, cellulose structure and biosynthesis, cellulose synthase gene and other genes related to cellulose synthesis, we comprehensively expounds the research progress of regulation of cell wall formation and root development mechanism by cellulose synthesis related genes, aiming to provide a reference for understanding the molecular mechanism of rice root formation and root breeding.
