Abstract:
This study integrated and analysisd 54 QTLs related to node numbers on main stem based on the physical map of soybean reference genome for the first time. 11 confidence intervals with good reproducibility were obtained by overview analysis on the D1b, C2, B1, F, L and I linkage groups, and the L-linked group had more reciprocal confidence intervals. Gene annotation of the obtained candidate segments yielded 488 candidate genes, among which Glyma.11G087300, Glyma.20G014300, Glyma.13G221400, Glyma.06G243500, Glyma.13G052900 and Glyma.13G052700 participated in the plant hormone signal transduction (ID: Ko04075). It was speculated that these six genes play the genetic regulation role of soybean main stem through the gibberellin pathway and the auxin pathway. The pathways and candidate genes directly related to stem growth and number of main stem segments discovered in this study will provide new ideas for the construction of ideal plant type and soybean molecular assisted breeding.
