TSF PEBP (phosphatidylethanolamine-binding protein) family protein [Arabidopsis thaliana (thale cress)] - Gene

Summary

Go to the top of the page Help

Official Symbol: TSF
Official Full Name: PEBP (phosphatidylethanolamine-binding protein) family protein
Primary source: TAIR:AT4G20370
Locus tag: AT4G20370
See related: Araport:AT4G20370
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: F9F13.20; F9F13_20; TWIN SISTER OF FT
Summary: Encodes a floral inducer that is a homolog of FT. Plants overexpressing this gene flower earlier than Col. Loss-of-function mutations flower later in short days. TSF and FT play overlapping roles in the promotion of flowering, with FT playing the dominant role.TSF sequences show extensive variation in different accessions and may contribute to quantitative variation in flowering time in these accessions. TSF has a complex pattern of spatial expression; it is expressed mainly in phloem and expression is regulated by daylength and vernalization.

Results sugest that flowering locus t protein (FT)/TWIN SISTER OF FT protein (TSF) and TERMINAL FLOWER 1 protein (TFL1) play antagonistic roles in the determination of inflorescence meristem identity, and that FT/TSF are more important than TFL1 in this process.
Title: Genetic interactions reveal the antagonistic roles of FT/TSF and TFL1 in the determination of inflorescence meristem identity in Arabidopsis.
With TSF-overexpressing plants as the rootstock, the flowering time of ft tsf scion plants was only slightly accelerated. This study did not detect movement of TSF from the roots into the shoot of the scion plants.
Title: FLOWERING LOCUS T has higher protein mobility than TWIN SISTER OF FT.
The drought escape response requires GI, FT/TSF, and AGL20 proteins in Arabidopsis.Abscisic acid up-regulates TSF expression in a photoperiod-dependent manner.
Title: GIGANTEA enables drought escape response via abscisic acid-dependent activation of the florigens and SUPPRESSOR OF OVEREXPRESSION OF CONSTANS.
TSF has a positive effect on blue light-induced stomatal opening in Arabidopsis.
Title: TWIN SISTER OF FT, GIGANTEA, and CONSTANS have a positive but indirect effect on blue light-induced stomatal opening in Arabidopsis.
Data indicate that BRANCHED1 (BRC1) interacts with the florigen proteins FLOWERING LOCUS T (FT) and TWIN SISTER OF FT (TSF) but not with TERMINAL FLOWER1, a floral repressor.
Title: BRANCHED1 interacts with FLOWERING LOCUS T to repress the floral transition of the axillary meristems in Arabidopsis.
The two florigen genes, FT and TSF, are an important key to linking the floral transition and lateral shoot development to maximize the reproductive success of a plant.
Title: The florigen genes FT and TSF modulate lateral shoot outgrowth in Arabidopsis thaliana.
Expression of TSF was increased in miR399b-overexpressing plants and pho2 mutants at 23 degrees C, suggesting that their early flowering phenotype is associated with TSF upregulation.
Title: The role of the miR399-PHO2 module in the regulation of flowering time in response to different ambient temperatures in Arabidopsis thaliana.
provide a mechanistic basis for the role of cytokinins in flowering, and demonstrate that the redundant genes FT and TSF are differently regulated by distinct floral-inducing signals
Title: Cytokinin promotes flowering of Arabidopsis via transcriptional activation of the FT paralogue TSF.
Expression of FT or TSF in the phloem is sufficient to overcome the late-flowering phenotype of ft-10 tsf-1.
Title: Genetic and spatial interactions between FT, TSF and SVP during the early stages of floral induction in Arabidopsis.
Here we show that FT mRNA is required in phloem companion cells where it acts partially redundant with its paralog TWIN SISTER OF FT (TSF) to induce flowering.
Title: Export of FT protein from phloem companion cells is sufficient for floral induction in Arabidopsis.
