摘要
稻米淀粉的形成是影响水稻产量和品质的决定性因素之一。因此,开展稻米淀粉形成过程中所涉及关键酶的研究是非常必要的。随着分子生物学技术的快速发展,有关稻米淀粉品质的研究也越来越深入,并取得了较大进展。该文对水稻淀粉品质形成过程中的关键酶及其分子生物学研究进展进行了较为详尽的综述,主要包括ADP葡萄糖焦磷酸化酶、淀粉合成酶、淀粉分支酶和淀粉去分支酶等,并对该领域的发展趋势进行了展望。
The composition, structure and accumulation of rice starch are key factors affecting grain quality and yield. Therefore, the key enzymes involved in the formation of rice starch need to be studied. With the development of molecular biology techniques, research into rice starch quality has made extensive progress. This review summarizes the progress of these key enzymes, including ADP-glucose pyrophosphorylase, starch synthase, starch branching enzyme and de-branching enzyme, and their roles involved in rice starch biosynthesis. Prospects for future research are also discussed.
