AI Technical Summary
Technical Problem
Existing methods for inducing male sterility in rice are costly or inefficient, and there is limited research on genes affecting pollen germination and tube growth, hindering the development of male-sterile rice varieties.
Method used
Suppressing the expression of the Os05g20150 gene, which is involved in pollen germination and tube elongation, using methods such as T-DNA insertion or CRISPR-Cas9 gene editing, to induce male sterility in rice.
Benefits of technology
The method effectively produces male-sterile rice with reduced pollen germination and tube elongation, improving breeding methods and minimizing environmental impact, and can be applied to various rice varieties.

Abstract
The present invention relates to a method for producing male sterility and male sterile rice produced therefrom. According to the present invention, when the Os05g20150 gene is mutated and its expression and function are suppressed, pollen germination and pollen tube elongation are reduced, thereby causing male sterility. Therefore, the method for producing a male sterile line through the regulation of the activity of the Os05g20150 gene according to the present invention and the male sterile line produced therefrom are intended to effectively improve existing breeding methods. Since they can be used stably with almost no environmental influence, they can contribute significantly to the development of the rice breeding industry.
