El-b3a gene in soybean growth period and coding protein thereof

Abstract

The invention relates to an el-b3a gene in a soybean growth period and a coding protein thereof. The gene sequence of the el-b3a gene in the soybean growth period is shown as a sequence list Seq ID No:1, and the amino acid sequence of the coding protein of the el-b3a gene in the soybean growth period is shown as a sequence list Seq ID No:2. By means of relevant heredity and molecular functional verification of varieties, the el-b3a gene has a flowering promoting function as compared with El genes.

Description

technical field [0001] The invention relates to soybean growth stage e1-b3a gene and its encoded protein. Background technique [0002] The E1 gene is located near the centromere, and no functional gene has been cloned since Bernard (1971) reported it. Since the gene is located near the centromere (pericentromeric region), the genetic recombination rate is low, which is not conducive to the use of map-based cloning to clone the gene. The name of the invention patent: a soybean growth stage E1 gene and its encoded protein, patent application No.: 201210112662.9, after publishing the E1 gene sequence and its corresponding protein sequence, it is proved that the soybean growth stage E1 gene has a strong physiological function of inhibiting soybean flowering. Although its protein sequence cannot identify the B3 domain, it has a distant relationship with the B3 domain gene. The B3 domain gene is a relatively conserved plant-specific transcription factor, generally only 100-120 ...

AI Technical Summary

Problems solved by technology

In soybean cultivars, how the mutation of the E1 gene affects the soybean growth period (flowering period and maturity period) is a very important scientific question, and there is no related research report at the molecular level.
