TLDR
FLOWERING LOCUS T (FT) is a conserved promoter of flowering that acts downstream of various regulatory pathways, including one that mediates photoperiodic induction through CONSTANS (CO), and is expressed in the vasculature of cotyledons and leaves.Abstract:
FLOWERING LOCUS T (FT) is a conserved promoter of flowering that acts downstream of various regulatory pathways, including one that mediates photoperiodic induction through CONSTANS (CO), and is expressed in the vasculature of cotyledons and leaves. A bZIP transcription factor, FD, preferentially expressed in the shoot apex is required for FT to promote flowering. FD and FT are interdependent partners through protein interaction and act at the shoot apex to promote floral transition and to initiate floral development through transcriptional activation of a floral meristem identity gene, APETALA1 (AP1). FT may represent a long-distance signal in flowering.read more

TL;DR: It is concluded that FT protein acts as a long-distance signal that induces Arabidopsis flowering, and evidence that FT does not activate an intermediate messenger in leaves is provided.

Natural variation in Ghd7 is an important regulator of heading date and yield potential in rice
Weiya Xue,Yongzhong Xing,Xiaoyu Weng,Yu Zhao,Weijiang Tang,Lei Wang,Hongju Zhou,Sibin Yu,Caiguo Xu,Xianghua Li,Qifa Zhang +10 more
TL;DR: It is shown that the quantitative trait locus (QTL) Ghd7, isolated from an elite rice hybrid and encoding a CCT domain protein, has major effects on an array of traits in rice, including number of grains per panicle, plant height and heading date.

miR156-Regulated SPL Transcription Factors Define an Endogenous Flowering Pathway in Arabidopsis thaliana
TL;DR: It is revealed that microRNA156-targeted SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) genes not only act downstream of FT/FD, but also define a separate endogenous flowering pathway.

TL;DR: Progress is reported in defining the diverse genetic mechanisms that enable plants to recognize winter, spring and autumn to initiate flower development.
Journal ArticleDOI
Hd3a protein is a mobile flowering signal in rice
TL;DR: It is shown that the protein encoded by Hd3a, a rice ortholog of FT, moves from the leaf to the shoot apical meristem and induces flowering in rice, suggesting that the Hd 3a protein may be the rice florigen.

TL;DR: FLOWERING LOCUS T (FT), which acts in parallel with the meristem-identity gene LEAFY (LFY) to induce flowering of Arabidopsis, was isolated by activation tagging and the deduced sequence was similar to the sequence of TERMINAL FLOWER 1 (TFL1), an inhibitor of flowering that also shares sequence similarity with membrane-associated mammalian proteins.

CONSTANS mediates between the circadian clock and the control of flowering in Arabidopsis

TL;DR: It is shown that expression of CONSTANS (CO), a gene that accelerates flowering in response to long days, is modulated by the circadian clock and day length, suggesting mechanisms by which day length regulates flowering time.

A pair of related genes with antagonistic roles in mediating flowering signals.
TL;DR: Flowering in Arabidopsis is promoted via several interacting pathways and FT acts in part downstream of CO and mediates signals for flowering in an antagonistic manner with its homologous gene, TERMINAL FLOWER1 (TFL1).
