Plant strain associated proteins PROG 2, encoding gene and application thereof

Abstract

The invention discloses plant strain associated proteins PROG 2 as well as an encoding gene and application thereof. The plant strain associated proteins PROG 2 provided by the invention are as follow a1) or a2) or a3), wherein a1) is a protein with an amino acid sequence shown in a sequence 2 in a sequence table; a2) is a fusion protein obtained by connecting a label to a N terminal and/or a C terminal of the protein shown in the sequence 2 in the sequence table; a3) is a plant strain associated protein obtained by substitution and/or deletion and/or addition of one or more amino acid residues of the protein shown by a1) or a2). Experiments prove that the plant strain associated protein PROG 2 has a very important role in regulating and controlling the rice plant type and the yield, and has a wide prospect in cultivation of new varieties of high-yield rice.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a plant strain-related protein PROG2 and its coding gene and application. Background technique [0002] Rice, as one of the most important food crops in the world, feeds more than 50% of the world's population. However, recent studies have shown that in the top three rice producing countries, China, India, and Indonesia, 78%, 37%, and 81% of the rice-producing areas, respectively, had stagnated rice production from 1961 to 2008, and rice cultivars Narrow genetic background and backward breeding technology are the main reasons for this phenomenon. [0003] Common wild rice is the ancestor of cultivated rice in Asia. During the evolution of wild rice into cultivated rice, through natural selection and artificial selection, the genetic diversity and the number of alleles decreased. According to statistics, the number of alleles in cultivated rice is about 60% of that in wi...

Problems solved by technology

According to statistics, the number of alleles in cultivated rice is about 60% of that in wild rice, which leads to the genetic bottleneck problem faced by the current rice variety breeding
