Abstract

The invention discloses the application of the rice OsRHD1‑1 gene in the cultivation of rice male sterility lines. The present invention constructs a gene knockout vector by designing a knockout target of the OsRHD1-1 gene, and performs genetic transformation in rice, and finds that the loss of OsRHD1-1 gene function can lead to pollen sterility, which is helpful for a new type of male sterile line The development of hybrid breeding is facilitated.

Description

technical field

[0001] The invention relates to the technical field of bioengineering, in particular to the application of the rice OsRHD1-1 gene in the cultivation of rice male sterility lines. Background technique

[0002] Rice is one of the most important food crops in the world. How to increase rice production to meet the growing food demand is an urgent problem to be solved today. Due to the limited arable land area and fresh water resources in our country, the method of increasing rice yield per unit area is the main way to increase rice yield. There are many factors that affect the yield of rice. The intrinsic genetic characteristics that affect the number of tillers per plant, the number of grains per panicle and the grain weight of rice are the determinants of rice yield; external factors include abiotic stresses such as light, temperature, water and salinity and The biological stress of diseases and insect pests has an important impact on the yield; in addition, h...
