Cis-regulatory changes at FLOWERING LOCUS T mediate natural variation in flowering responses of Arabidopsis thaliana.
Flowering time, a critical adaptive trait, is modulated by several environmental cues. These external signals converge on a small set of genes that in turn mediate the flowering response. Mutant analysis and subsequent molecular studies have revealed that one of these integrator genes, FLOWERING LOCUS T (FT), responds to photoperiod and temperature cues, two environmental parameters that greatl...
متن کاملVariation in shade-induced flowering in Arabidopsis thaliana results from FLOWERING LOCUS T allelic variation
Plants have evolved developmental mechanisms to ensure reproduction when in sub-optimal local environments. The shade-avoidance syndrome is one such mechanism that causes plants to elongate and accelerate flowering. Plants sense shade via the decreased red:far-red (R:FR) ratio that occurs in shade. We explored natural variation in flowering behavior caused by a decrease in the R:FR ratio of Ara...
متن کاملPolycomb-Group Proteins and FLOWERING LOCUS T Maintain Commitment to Flowering in Arabidopsis thaliana.
The switch from vegetative to reproductive growth is extremely stable even if plants are only transiently exposed to environmental stimuli that trigger flowering. In the photoperiodic pathway, a mobile signal, florigen, encoded by FLOWERING LOCUS T (FT) in Arabidopsis thaliana, induces flowering. Because FT activity in leaves is not maintained after transient photoperiodic induction, the molecu...
متن کاملGraft-transmissible action of Arabidopsis FLOWERING LOCUS T protein to promote flowering.
Day length perceived by a leaf is a major environmental factor that controls the timing of flowering. It has been believed that a mobile, long-distance signal called florigen is produced in the leaf, and is transported to the shoot apex where it triggers floral morphogenesis. Grafting experiments have shown that florigen is transmissible from a donor plant that has been subjected to inductive d...
متن کاملPlanned parenthood in Arabidopsis: FLOWERING LOCUS C.
“Ontogeny recapitulates phylogeny” goes the line that persists in folkloric fashion in academic biology, most likely because it is so much fun to say. The saying is no longer taken literally by scientists who value their reputation, and Ernst Haeckel, the nineteenth-century German zoologist who first coined the phrase, has been widely discredited for having manipulated anatomical drawings so as...
