Application of SCWBC11 protein in culture of male sterility line of rice

Abstract

The invention discloses an application of a SCWBC11 protein in culture of a male sterility line of rice, and provides an application of a substance which is expressed by an OSWBC11 protein coding gene in a silent or inactivated target plant to culture of a male sterile plant. In the application, the amino acid sequence of the OSWBC11 protein is the sequence 2 in the sequence table. The target plant is dicotyledon or monocotyledon and monocotyledon is specifically rice. Experiments verify that by adopting an RNA (Ribonucleic Acid) interference method, OSWBC11 protein expression interference is carried out on wild rice Nipponbare, so that the protein function is lost and rice cannot produce pollen, thereby forming the male sterility line. Therefore, the protein has an important application value to the forming mechanism of pollen of rice and the application of the protein to crossbreeding of rice can be explored.

Description

technical field

[0001] The invention relates to the field of biotechnology, in particular to the application of an OSWBC11 protein in cultivating male sterile lines of rice. Background technique

[0002] Rice is one of the three major food crops in the world, and about half of the world's population uses rice as the main food. China's rice cultivation area accounts for about 23% of the world's total, and its rice production accounts for about 37% of the world's total. China's rice planting area accounts for 30% of the country's grain crop planting area, but the total output accounts for more than 42% of the grain crop output, and the average yield per unit area is 45.7% higher than that of the entire grain crop. One of the important reasons is the heterosis. widely used. Heterosis is a common phenomenon in the biological world. It refers to the hybridization of two genetically different parents. Hybrid rice shows significant heterosis in many traits, comprehensively manif...
