The functional confirmation and model of QNE1, a key flowering regulator determining the length of the vegetative period in soybean cultivars.

Caption

A, Overexpression of Qne1 accelerates flowering time in soybean. W82, wild type of Williams 82; SQZ#L51 and SQZ#L66, transgenic lines of Zhonghuang 13 overexpressing Qne1. B-C, Overexpression of Qne1 promotes flowering and changes in leaf shape in Brassica napus. B Representative nontransgenic wild-type B. napus plant, C, Representative transgenic B. napus line overexpressing Qne1. D, Proposed model for Qne1 function. Compared with the E1 photoperiodic flowering pathway (left), the QNE1 pathway may control flowering time independently of daylength. Other functions for QNE1 in morphogenesis, such as leaf shape, are also suggested. Photo credit: Hong Zhai and Zhengjun Xia.
