大豆光周期效应GmGBP1基因启动子多态性分析
Analysis of polymorhpism in GmGBP1 promoter involved in soybean photoperiod response
摘要
Abstract
Flowering period is one of the most important ecological traits of adaptation in soybean and controlled by multiple genes.Molecular biology studies have shown that the diversity of soybean flowering period controlled by photoperiod is attributed to the variation of photoperiod-related genes and their combination of variation.GmGBP1 is an important gene in the flowering process of plants and its promoter is also strongly induced by short day conditions.However,at present,the relationship between polymorphism of the promoter sequence of soybean GmGBP1 and its flowering time is still unclear.In this study,the promoter sequences of GmGBP1 from 36 soybean germplasms with different flowering habits were cloned and sequenced,and the natural allelic variation of GmGBP1 promoter was explored for the natural variation of GmGBP1 promoter sequence relationship with flowering period.The results showed that SNP-796 was closely related to flowering time,of which SNP-796G was an excellent allele for shortening soybean growth stage.The 3 major haplotypes also showed significant (P ＜ 0.01) correlation with flowering stage.Haplotypes 2 and 3 were shortened haplotypes in soybean flowering stage.关键词
