CsFTL3, a chrysanthemum FLOWERING LOCUS T-like gene, is a key regulator of photoperiodic flowering in chrysanthemums
Chrysanthemum is a typical short-day (SD) plant that responds to shortening daylength during the transition from the vegetative to the reproductive phase. FLOWERING LOCUS T (FT)/Heading date 3a (Hd3a) plays a pivotal role in the induction of phase transition and is proposed to encode a florigen. Three FT-like genes were isolated from Chrysanthemum seticuspe (Maxim.) Hand.-Mazz. f. boreale (Maki...
متن کاملEffect of Photoperiodic Floral Induction on the Metabolism of a Gibberellin Precursor, (-)-Kaurene, in Pharbitis nil.
Pharbitis nil seedlings rapidly metabolized (-)-kaurene-17-(14)C administered to the cotyledons. Less than 20% of the radioactivity was recovered by extraction of the cotyledons on the following day. Of this the major metabolite was an unidentified acidic material which did not correspond chromatographically to any of the known gibberellins.Significant differences were observed between the radi...
متن کاملPhotoperiodic flowering of Arabidopsis : integrating genetic and physiological approaches to characterization of the floral stimulus
In many plants the transition from vegetative growth to flowering is controlled by environmental cues. One of these cues is day length or photoperiod, which synchronizes flowering of many species with the changing seasons. Recently, advances have been made in understanding the molecular mechanisms that confer photoperiodic control of flowering and, in particular, how inductive events occurring ...
متن کاملFloral induction and determination: where is flowering controlled?
Flowering is controlled by a variety of interrelated mechanisms. In many plants, the environment controls the production of a floral stimulus, which moves from the leaves to the shoot apex. Apices can become committed to the continuous production of flowers after the receipt of sufficient amounts of floral stimulus. However, in some plants, the commitment to continued flower production is evide...
