The FLOWERING LOCUS T/TERMINAL FLOWER 1 family in Lombardy poplar.
Genes in the FLOWERING LOCUS T (FT) and TERMINAL FLOWER 1 (TFL1) family have been shown to be important in the control of the switch between vegetative and reproductive growth in several plant species. We isolated nine members of the FT/TFL1 family from Lombardy poplar (Populus nigra var. italica Koehne). Sequence analysis of the members of the FT/TFL1 family revealed considerable homology with...
متن کاملRepression of FLOWERING LOCUS C and FLOWERING LOCUS T by the Arabidopsis Polycomb Repressive Complex 2 Components
Polycomb group (PcG) proteins are evolutionarily conserved in animals and plants, and play critical roles in the regulation of developmental gene expression. Here we show that the Arabidopsis Polycomb repressive complex 2 (PRC2) subunits CURLY LEAF (CLF), EMBRYONIC FLOWER 2 (EMF2) and FERTILIZATION INDEPENDENT ENDOSPERM (FIE) repress the expression of FLOWERING LOCUS C (FLC), a central represso...
متن کاملStructural features determining flower-promoting activity of Arabidopsis FLOWERING LOCUS T.
In Arabidopsis thaliana, the genes FLOWERING LOCUS T (FT) and TERMINAL FLOWER1 (TFL1) have antagonistic roles in regulating the onset of flowering: FT activates and TFL1 represses flowering. Both encode small, closely related transcription cofactors of ∼175 amino acids. Previous studies identified a potential ligand binding residue as well as a divergent external loop as critical for the differ...
متن کاملDissecting cis-regulation of FLOWERING LOCUS T.
Flowering in many plants is strongly influenced by daylength. Arabidopsis thaliana FLOWERING LOCUS T (FT) encodes a small peptide that is now widely recognized as a major component of florigen, a systemic signal that induces flowering in response to daylength (Turck et al., 2008). FT is expressed in phloem companion cells, and the protein is translocated through the phloem to the shoot apical m...
متن کاملNatural Variation of the RICE FLOWERING LOCUS T 1 Contributes to Flowering Time Divergence in Rice
In rice (Oryza sativa L.), there is a diversity in flowering time that is strictly genetically regulated. Some indica cultivars show extremely late flowering under long-day conditions, but little is known about the gene(s) involved. Here, we demonstrate that functional defects in the florigen gene RFT1 are the main cause of late flowering in an indica cultivar, Nona Bokra. Mapping and complemen...
