Abstract:
For more accurate excavation in candidate genes of soybean plant height trait, 249 QTLs related to plant height traits were used to integrate base on soybean genome physical map, with the method of Overview analysis, 32 confidence intervals with good reproducibility were obtained and located on linkage D1b, N, C1, A1, C2, M, K, O, B1, F, J, D2, G and L. Among 14 linkage groups, D1b, A1, C2, M, F and L had more confidence intervals. Gene annotation of the candidate segments yields a plant hormone signal transduction pathway, which was closely related to plant physiological processes such as plant cell enlargement, differentiation, stem growth, dormancy, fruit ripening and stress resistance. The pathway contains 13 candidate genes which closely related soybean plant height traits. Among these 13 genes, 9 genes were annotated to encode auxin-responsive proteins, 3 genes were annotated to encode abscisic acid-related proteins, and 1 gene was a GH3 auxin-responsive promoter. This study not only shed new light on excavating candidate genes for soybean plant type traits but also construct ideal soybean type and promoting molecular-assisted breeding.
