Rice heading period related protein, and coding gene and application thereof

Abstract

The invention discloses rice heading period related protein, and a coding gene and application thereof. The rice heading period related protein is a protein composed of an amino acid sequence shown as SEQ ID No. 29 or a protein formed by subjecting the amino acid sequence shown as SEQ ID No. 29 to addition, substitution, insertion or deletion of one or multiple amino acids, related to a rice heading period and derived from the SEQ ID No. 29. The coding gene has a nucleotide sequence shown as SEQ ID No. 30 and can serve as a gene supplier to improve the heading period of rice varieties.

Description

1. Technical field [0001] The invention relates to a rice heading date related protein and its coding gene and application, belonging to the field of plant genetic engineering. 2. Background technology [0002] Rice is the most important food crop in the world, and rice is grown in more than 100 countries around the world (Fitzgerald MA, et al, PlantSci, 2009, 14(3):133-139). Rice provides 21% calories and 15% protein for the whole world population (Fitzgerald MA, et al, Plant Sci, 2009, 14(3):133-139; MiuraK, et al, Trends Plant Sci, 2011, 16(6): 319-326), provide 70% calories and 65% protein (Xie Xinhua et al., Guangdong Agricultural Sciences, 2003, 30 (6): 2-4) for the population of our country, guaranteeing rice production is very important to the whole world, especially to my country's food security important. Breeding new rice varieties with high yield, high quality and multi-resistance has become an important goal of breeders in various countries. [0003] Heading da...

Problems solved by technology

The main reason is that traditional target groups (such as F 2 / F 3 、BC l , DHs and RILs) there are complex interactions between QTLs and the interference of genetic background among individuals, which makes the estimation of QTLs inaccurate and makes fine mapping and cloning more difficult
