Title:
PLANT GRAIN SIZE REGULATION GENE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/037338
Kind Code:
A1
Abstract:
Disclosed are a plant grain size regulation gene and use thereof, which belong to the technical field of biology. PCFS gene mutants in different crops are obtained by gene editing, and by means of experiments and statistical analysis, it is found that the mutants have a phenotype of enlarged plant grain and part of the mutants have a phenotype of improved stress resistance. The provided gene, mutants, and method for use same are beneficial to increase the crop yield and improve the quality and enhance the resistance of plants to an adverse environment, provide gene resources and technical support for cultivating new plant varieties with large grain weight and high stress resistance, and thereby have important significance and application value for improvement of agronomic traits of crops and breeding of high-yield and high stress-resistant molecules.
