Journal ArticleDOI
CONSTANS acts in the phloem to regulate a systemic signal that induces photoperiodic flowering of Arabidopsis.
Hailong An,Clotilde Roussot,Paula Suárez-López,Laurent Corbesier,Coral Vincent,Manuel Piñeiro,Shelley R. Hepworth,Aidyn Mouradov,Samuel Justin,Colin G. N. Turnbull,George Coupland +10 more
TL;DR: It is proposed that, partly through the activation of FT, CO regulates the synthesis or transport of a systemic flowering signal, thereby positioning this signal within the established hierarchy of regulatory proteins that controls flowering.
Journal ArticleDOI
Antagonistic regulation of flowering‐time gene SOC1 by CONSTANS and FLC via separate promoter motifs
Shelley R. Hepworth,Shelley R. Hepworth,Federico Valverde,Dean Ravenscroft,Aidyn Mouradov,George Coupland +5 more
TL;DR: It is proposed that CO is recruited to a separate promoter element by a DNA‐binding factor and that activation by CO is impaired when FLC is bound to an adjacent CArG motif.
Journal ArticleDOI
Functional importance of conserved domains in the flowering-time gene CONSTANS demonstrated by analysis of mutant alleles and transgenic plants
Frances Robson,Maria Manuela Ribeiro Costa,Shelley R. Hepworth,Igor Vizir,Manuel Piñeiro,Paul H. Reeves,Joanna Putterill,George Coupland +7 more
TL;DR: It is shown that CONSTANS is a member of an Arabidopsis gene family that comprises 16 other members, and analysis of seven classical co mutant alleles demonstrated that the mutations all occur within either the zinc finger region or the CCT domain, confirming that the two regions of homology are important for CO function.
Journal ArticleDOI
CER4 Encodes an Alcohol-Forming Fatty Acyl-Coenzyme A Reductase Involved in Cuticular Wax Production in Arabidopsis
TL;DR: Data indicate that CER4 is an alcohol-forming FAR that has specificity for very-long-chain fatty acids and is responsible for the synthesis of primary alcohols in the epidermal cells of aerial tissues and in roots.
Journal ArticleDOI
BLADE-ON-PETIOLE-dependent signaling controls leaf and floral patterning in Arabidopsis.
TL;DR: It is shown that two NPR1-like genes, BLADE-ON-PETIOLE1 (BOP1) and BOP2, function redundantly to control growth asymmetry, an important aspect of patterning in leaves and flowers.
