Gene Details:

• Gene ID: Sobic.010G045100
• Gene Symbol: SbFT1
• Gene Name: FLOWERING LOCUS T 1
• Genome: Sorghum bicolor v.3.1.1
• Species: Sorghum bicolor

Functional Descriptions:

• Reinforcing the direct effect of SbGhd7, SbEhd1 OE activated the promoters of three functional florigens (SbFT1, SbFT8 and SbFT10), dramatically accelerating flowering.
• Sorghum has three putative florigens activating flowering: SbFT1/SbCN15, SbFT8/SbCN12 and SbFT10/SbCN8. SbFT8 and SbFT10 are strongly induced by SD photoperiods in sensitive genotypes, and all the three genes are capable of activating flowering in transgenic Arabidopsis, with SbFT10 having the strongest effect.
• Here we characterized sorghum FLOWERING LOCUS T (SbFT) genes to establish a molecular road map for mechanistic understanding. Out of 19 PEBP genes, SbFT1, SbFT8 and SbFT10 were identified as potential candidates for encoding florigens using multiple approaches.
• For this reason, we focused on the three genes, SbFT1, SbFT8 and SbFT10, to further characterize their involvement in flowering.
