“…These FT genes are the result of tandem and whole genome duplications in soybean (Thakare, Kumudini, & Dinkins, 2011;Wang et al, 2015). Among these genes, GmFT2a and GmFT5a have been found to promote flowering following the expression of the phytochrome PHYA in soybean, and show the same relationship as AtFT and AtTSF (TWIN SISTER of FT) in Arabidopsis (Nan et al, 2014;Takeshima et al, 2016;Yamaguchi, Kobayashi, Goto, Abe, & Araki, 2005). Expression of both GmFT2a and GmFT5a is up-regulated under SD conditions, whereas they are significantly down-regulated under long-day (LD) conditions (Kong et al, 2010;Sun et al, 2011;Xu et al, 2013).…”
