Phloem-Borne FT Signals Flowering in Cucurbits
Approximately 45 years ago, Zeevaart (1962) wrote that the identification of florigen, a phloem-borne signaling molecule that acts to initiate photoperiodic-dependent flowering, was the most urgent problem in the study of the physiology of flowering and expressed hope that the recent isolation of a flower-inducing extract from Xanthium (Lincoln et al., 1960) would lead to a solution. In the ens...
متن کاملThe nature of floral signals in Arabidopsis. II. Roles for FLOWERING LOCUS T (FT) and gibberellin
Signals produced in leaves are transported to the shoot apex where they cause flowering. Protein of the gene FLOWERING LOCUS T (FT) is probably a long day (LD) signal in Arabidopsis. In the companion paper, rapid LD increases in FT expression associated with flowering driven photosynthetically in red light were documented. In a far red (FR)-rich LD, along with FT there was a potential role for ...
متن کاملLight signals and flowering.
Physiological studies over a long period have shown that light acts to regulate flowering through the three main variables of quality, quantity, and duration. Intensive molecular genetic and genomic studies with the model plant Arabidopsis have given considerable insight into the mechanisms involved, particularly with regard to quality and photoperiod. For photoperiodism light, acting through p...
متن کاملFLOWERING LOCUS T protein may act as the long-distance florigenic signal in the cucurbits.
Cucurbita moschata, a cucurbit species responsive to inductive short-day (SD) photoperiods, and Zucchini yellow mosaic virus (ZYMV) were used to test whether long-distance movement of FLOWERING LOCUS T (FT) mRNA or FT is required for floral induction. Ectopic expression of FT by ZYMV was highly effective in mediating floral induction of long-day (LD)-treated plants. Moreover, the infection zone...
متن کاملZCN8 encodes a potential orthologue of Arabidopsis FT florigen that integrates both endogenous and photoperiod flowering signals in maize
Higher plants use multiple perceptive measures to coordinate flowering time with environmental and endogenous cues. Physiological studies show that florigen is a mobile factor that transmits floral inductive signals from the leaf to the shoot apex. Arabidopsis FT protein is widely regarded as the archetype florigen found in diverse plant species, particularly in plants that use inductive photop...
