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...

FLOWERING LOCUS T duplication coordinates reproductive and vegetative growth in perennial poplar.

Annual plants grow vegetatively at early developmental stages and then transition to the reproductive stage, followed by senescence in the same year. In contrast, after successive years of vegetative growth at early ages, woody perennial shoot meristems begin repeated transitions between vegetative and reproductive growth at sexual maturity. However, it is unknown how these repeated transitions...

Natural 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...

Structural 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...

Distribution of phytoplasma diseases in the Lombardy poplar tree population of Zagreb urban area

Phytoplasmas are uncultivable prokaryotic wall-less pathogens belonging to the class Mollicutes that inhabit plant phloem and insects. Their identification and classification is difficult and mainly based on the polymorphism of their 16S rRNAgene sequences. Aster yellows (AY; 'Candidatus Phytoplasma asteris') phytoplasmas (ribosomal subgroup 16SrI-P) had been previously identified in several Po...
