...Antoine Martin; Hélène Adam; Mercedes Díaz-Mendoza; Marek Żurczak; Nahuel D. González-Schain; Paula Suárez-López The photoreceptor phytochrome B (PHYB) and the homeodomain protein BEL5 are involved in the response of potato tuber induction to the photoperiod. However, whether they act...

... in the photoperiod-response pathway (Hayama and Coupland, 2003 ; Yanovsky and Kay, 2003), acts in the phloem companion cells to trigger floral development at the apex, and controls a systemic signal that crosses graft junctions. The mechanism by which CO acts in the phloem involves cell-autonomous activation...

...Patrick Achard; Alan Herr; David C. Baulcombe; Nicholas P. Harberd Floral initiation and floral organ development are both regulated by the phytohormone gibberellin (GA). For example, in short-day photoperiods, the Arabidopsis floral transition is strongly promoted by GA-mediated activation...

... of the mutation is strongest under short photoperiods, which delay flowering of Arabidopsis . The mutant has additional phenotypes, including premature termination of the shoot and an alteration of phyllotaxy along the stem, suggesting that ESD4 has a broader role in plant development. Genetic analysis indicates...
