 ===Function===
-FLOWERING LOCUS T 1 (RFT1) is a florigen gene in rice  (Figure 1), because an RFT1:GFP fusion protein localized in the shoot apical meristem (SAM) under LD conditions (Figure 2). RFT1 is the closest homolog to Heading date 3a (Hd3a) and is a major floral activator under LD conditions..RFT1 and Hd3a regulate rice flowering under LD and SD conditions.OsMADS50, an LD floral activator, acts upstream of Ehd1 and RFT1.OsMADS14 and OsMADS15 act downstream of RFT1 in the SAM under LD conditions.Both positive (OsMADS50 and Ehd1) and negative (Hd1, phyB and Ghd7) regulators of RFT1 form a gene network that regulates LD flowering in rice The OsMADS50-Ehd1-RFT1 pathway is involved in floral activation under LD conditions(Figure 2 )<ref name="ref1" />.
+* RFT1 promotes flowering in the absence of Hd3a, and that both Hd3a and RFT1 are essential for flowering under SD conditions. <ref name="ref1" />.

 ===Mutation===
-Polymorphisms in the promoter region that lead to reduced expression levels of RFT1. An amino acid substitution (E105K) that leads to a functional defect in Nona Bokra RFT1. The E105K mutation is found only in indica, and a strong association was founded between the RFT1 haplotype and extremely late flowering in a functional Hd1 background.. Furthermore, SNPs in the regulatory region of RFT1 and the E105K substitution in 1,397 accessions show strong linkage disequilibrium with a flowering time–associated SNP.  <ref name="ref2" /> .
+* Mutants in OsMADS50, a rice ortholog of Arabidopsis SUPPRESOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1) did not flower up to 300 days after sowing under LD conditions, indicating that OsMADS50, which acts upstream of RFT1, promotes flowering under LD conditions.
-[http://www.ricedata.cn/reference/list/45205.htm]
+* A rice ortholog of Arabidopsis APETALA1, OsMADS14, was expressed in the floral meristem in wild-type but not in RFT1 RNAi plants, suggesting that OsMADS14 is activated by RFT1 protein in the SAM after the transition to flowering.
 ===Expression===
-Developmental expression of RFT1 in the SAM under LD conditions through stages 1-5 (Figure 3 ) <ref name="ref1" />.
+* Transcript levels of RFT1 were very low in wild-type plants throughout development. The similarity of Hd3a and RFT1 expression patterns under SD and LD conditions, and in vascular tissues, suggests that RFT1 could function redundantly with Hd3a in promoting floral transition under SD conditions[3].

+===Subcellular localization===
 ===Evolution===
-The ratios of nonsynonymous to synonymous substitutions suggest that the E105K mutation resulting in the defect in RFT1 occurred relatively recently. These findings indicate that natural mutations in RFT1 provide flowering time divergence under long-day conditions <ref name="ref2" /> .
+* RFT1 is the closest homolog of 13 FT-like genes in rice to Hd3a, with 91% identity in their deduced amino acid sequences and is located only 11.5 kb from Hd3a on chromosome 6
