Publication number: 20230365634Abstract: The present invention discloses a protein regulating nitrogen-use efficiency and yield of a plant and the use thereof. The present invention obtains a transgenic OsTCP19 rice and a rice OsTCP19 mutant by means of a transgenic technique and a CRISPR-Cas9 technique, respectively. Experiments have shown that compared with wild-type rice, the transgenic OsTCP19 rice has a reduced tiller number and a decreased nitrogen response ability, whereas compared with the wild-type rice, the rice OsTCP19 mutant has an increased tiller number. This indicates that the OsTCP19 protein has the function of regulating the plant yield and nitrogen-use efficiency, thus laying the foundation for cultivating varieties with a high yield and a high nitrogen-use efficiency.Type: ApplicationFiled: September 14, 2021Publication date: November 16, 2023Inventors: Chengcai CHU, Yongqiang LIU, Bin HU, Hongru WANG
