Gene Details:

Functional Descriptions:

  • Natural variants of FT2a and FT5a confer the long-juvenile (LJ) trait in soybean Selected FT variants repress AP1 and interact to enhance late maturity and yield
  • Both FT2a and FT5a show strong induction under SDs, induce early flowering when overexpressed, and delay flowering when downregulated by RNA interference (RNAi).
  • Analysis of loss-of-function mutants generated by genome editing has further indicated that FT2a and FT5a may have distinct roles in floral induction, as the flowering delay was observed predominantly in SDs for ft2a mutants, whereas the delay occurred mainly under LDs for fta5 mutants.
  • Two QTLs conferring the LJ trait, and identified them as two florigen genes, FT2a and FT5a, respectively.
  • FT2a and FT5a interact with a bZIP transcription factor, FDL19, which directly binds to the ACGT cis-element in the promoter of the APETALA1 homolog AP1a (Glyma.16G091300) to induce its transcription, thereby promoting soybean flowering.
  • Mutagenesis of GmFT2a and GmFT5a mediated by CRISPR/Cas9 contributes for expanding the regional adaptability of soybean.
  • Functional diversification of Flowering Locus T homologs in soybean: GmFT1a and GmFT2a/GmFT5a have opposite roles in controlling flowering and maturation。
