抑制水稻隐花色素基因OsCRY1a表达对水稻农艺性状的影响
Effects of Suppressing OsCRY1a Gene Expression on Rice Agronomic Traits
摘要
Abstract
Using primers designed according to the published sequence of OsCRYla gene, part of the gene fragment was obtained by PCR and a RNAi expression vector was constructed. The vector was then introduced into rice, leading to the downregulation of the expression level and loss-of-function of the gene. Based on the performance of the transgenic plants, the functions of OsCRYla was analyzed and deduced. The results indicated that suppressing the expression of OsCRYla retarded flowering for 16 d with the plant height and grain length significantly increased while other important agronomic traits remained unchanged apparently.关键词
