西南大学农学与生物科技学院、农业科学研究院教授何光华课题组在美国《国家科学院院刊》在线发表论文,介绍了水稻小穗侧生小花的发育调控机制的原创性研究成果,深度解析了稻花的发育调控机制,为水稻超高产分子设计育种奠定了基础。早在1937年就有科学家提出水稻“三花小穗”假说,认为水稻小穗中两个“无用”的颖片器官——护颖实际上是两个侧生小花退化而来,也就是说原始的水稻可能由三
He Guanghua, a professor at Southwest University’s College of Agronomy and Biotechnology, and a professor of Agricultural Science Research Institute, published an online paper in Proceedings of the National Academy of Sciences of the United States. The paper introduced the original research results on the development and regulation mechanism of lateral flower spikelets in rice. Rice flower development and regulation mechanism, laid the foundation for the design and breeding of super high molecular weight rice. As early as 1937, scientists proposed the hypothesis that the two “non-useful” glumes in the spikelet of rice - the Ying Ying is actually degenerated from two lateral florets , Which means that the original rice may be three
