dc.description.abstract | Sorghum is a typical short-day (SD) plant and its use in grain or biomass production in temperate
regions depends on its flowering time control, but the underlying molecular mechanism
of floral transition in sorghum is poorly understood.
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.
Phylogenetic analysis revealed that SbFT1 clusters with the rice Hd3a subclade, while SbFT8
and SbFT10 cluster with the maize ZCN8 subclade. These three genes are expressed in the leaf
at the floral transition initiation stage, expressed early in grain sorghum genotypes but late in
sweet and forage sorghum genotypes, induced by SD treatment in photoperiod-sensitive
genotypes, cooperatively repressed by the classical sorghum maturity loci, interact with
sorghum 14-3-3 proteins and activate flowering in transgenic Arabidopsis plants, suggesting
florigenic potential in sorghum.
SD induction of these three genes in sensitive genotypes is fully reversed by 1 wk of longday
treatment, and yet, some aspects of the SD treatment may still make a small contribution
to flowering in long days, indicating a complex photoperiod response mediated by SbFT
genes. | en_US |
