AI Technical Summary
Technical Problem
Existing technologies are insufficient to effectively control the tillering angle of rice, affecting plant type and yield, resulting in low light energy utilization and reduced yield.
Method used
By using genetic engineering technology, the OsSR1IP1 gene was overexpressed, and the OsSR1IP1 overexpression vector was transferred into rice using Agrobacterium-mediated transformation, resulting in stable inheritance and a significant increase in tillering angle.
Benefits of technology
The successful identification and regulation of rice tillering angle, which enhances lodging resistance and increases yield, has significant theoretical and applied value.

Abstract
This invention discloses the application of the OsSR1IP1 gene in regulating tillering angle in rice. It belongs to the field of plant genetic engineering technology. This invention uses genetic engineering technology to obtain transgenic rice that stably overexpresses OsSR1IP1. By comparing the growth of wild-type and OsSR1IP1-overexpressing transgenic rice, it was found that the tillering angle of OsSR1IP1-overexpressing transgenic rice plants was significantly increased. Therefore, this invention successfully identified a key gene regulating rice plant architecture, which has theoretical significance and application value for enhancing the lodging resistance and increasing yield of rice varieties, and is of great importance to agricultural development and national food security.
