Abstract
The application belongs to the technical field of genetic engineering, and provides application of a rice Os01g43740.1 gene in improving rice traits, wherein the rice traits include rice lodging resistance, drought resistance and low ear germination rate. The application comprises the following steps: step 1, obtaining of the CDS sequence of the Os01g43740.1 gene and construction of a plant expression vector; step 2, obtaining of a transgenic rice plant; and step 3, identification of a transgenic positive line. The Ubiquitin promoter, the CDS sequence of the Os01g43740.1 gene and GFP are fused for the first time, and the fusion gene is transformed into rice, so as to improve the rice lodging resistance, drought resistance and ear germination inhibition traits. The application has important theoretical value for elucidating the growth and development mechanism of rice, and can improve the rice lodging resistance and drought resistance and reduce the ear germination of rice through the transgenic means, so the application has important significance in production practice.
