Gene Details:

• Gene ID: TraesCS7B02G013100
• Gene Symbol: FT-B1
• Gene Name: FLOWERING LOCUS T
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Linkage mapping identifies a non-synonymous mutation in FLOWERING LOCUS T (FT-B1) increasing spikelet number per spike.
• The gene FLOWERING LOCUS T (FT-B1) emerged as candidate for the observed effect. In one of the parental lines, FT-B1 carried a non-synonymous substitution on position 19 of the coding sequence.
• FT-B1 only showed a minor effect on heading and flowering time (FT) which were dominated by a major QTL on chromosome 5A caused by segregation of the vernalization gene VRN-A1.
• Individuals carrying the FT-B1 allele with amino acid histidine had, on average, a higher number of spikelets (15.1) than individuals with the aspartic acid allele (14.3) independent of their VRN-A1 allele.
• Zebularine treatment is associated with deletion of FT-B1 leading to an increase in spikelet number in bread wheat.
