FRIGIDA delays flowering in Arabidopsis via a cotranscriptional mechanism involving direct interaction with the nuclear cap-binding complex.
A major determinant of flowering time in natural Arabidopsis (Arabidopsis thaliana) variants is FRIGIDA (FRI). FRI up-regulates expression of the floral repressor FLOWERING LOCUS C (FLC), thereby conferring a vernalization requirement and a winter annual habit. FRI encodes a novel nuclear protein with no conserved domains except for two coiled-coil regions. A mutation in the large subunit of th...
متن کاملA latitudinal cline in flowering time in Arabidopsis thaliana modulated by the flowering time gene FRIGIDA.
A latitudinal cline in flowering time in accessions of Arabidopsis thaliana has been widely predicted because the environmental cues that promote flowering vary systematically with latitude, but evidence for such clines has been lacking. Here, we report evidence of a significant latitudinal cline in flowering time among 70 Northern European and Mediterranean ecotypes when grown under ecological...
متن کاملFlowering Phenotype of Arabidopsis Plants Containing the FRIGIDA Gene'
We have compared the flowering response to vernalization, photoperiod, and far-red (FR) light of the Columbia (Col) and Landsberg erecfa (Ler) ecotypes of Arabidopsis into which the flowering-time locus FRIGIDA (FRI) has been introgressed with that of the wild types Col, Ler, and San Feliu-2 (Sf-2). In the early-flowering parenta1 ecotypes, Col and ler, a large decrease in flowering time in res...
متن کاملInvolvement of the nuclear cap-binding protein complex in alternative splicing in Arabidopsis thaliana
The nuclear cap-binding protein complex (CBC) participates in 5' splice site selection of introns that are proximal to the mRNA cap. However, it is not known whether CBC has a role in alternative splicing. Using an RT-PCR alternative splicing panel, we analysed 435 alternative splicing events in Arabidopsis thaliana genes, encoding mainly transcription factors, splicing factors and stress-relat...
متن کاملFitness effects associated with the major flowering time gene FRIGIDA in Arabidopsis thaliana in the field.
To date, the effect of natural selection on candidate genes underlying complex traits has rarely been studied experimentally, especially under ecologically realistic conditions. Here we report that the effect of selection on the flowering time gene FRIGIDA (FRI) reverses depending on the season of germination and allelic variation at the interacting gene FLOWERING LOCUS C (FLC). In field studie...
