AI Technical Summary

Technical Problem

Existing technologies cannot effectively utilize small-effect gene loci when regulating the heading date of rice, thus failing to meet the needs of rice breeding for heading date improvement. Furthermore, the understanding of genes affecting the heading date in natural variant populations of japonica rice is limited.

Method used

Transgenic plants were constructed using gene editing technology, and the SUS1 gene in rice was knocked out or interfered with. The results showed that knocking out the SUS1 gene could prolong the heading period of rice.

Benefits of technology

This study has enabled the extension of the heading period by knocking out the SUS1 gene in rice, resulting in the development of transgenic rice with a long heading period. This has broadened the rice planting area and may affect rice yield.

Abstract

The application discloses a gene SUS1 related to rice heading stage and application thereof, and the coding region nucleotide sequence of the gene is shown as SEQ ID NO:3. The gene of the application influences the rice heading stage. By using gene editing technology to edit the gene SUS1, the edited family can be significantly prolonged in the rice heading stage. The SUS1 gene can be applied to the rice breeding work as a gene influencing the rice heading stage in the future, and has great development value and application prospect.
