Role of FRIGIDA and FLOWERING LOCUS C in determining variation in flowering time of Arabidopsis.
Arabidopsis (Arabidopsis thaliana) accessions provide an excellent resource to dissect the molecular basis of adaptation. We have selected 192 Arabidopsis accessions collected to represent worldwide and local variation and analyzed two adaptively important traits, flowering time and vernalization response. There was huge variation in the flowering habit of the different accessions, with no simp...
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 کاملFRIGIDA 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...

INTRODUCTION During eukaryotic chromosome replication, both genetic and epigenetic information are accurately duplicated, which maintains identical cellular memory through mitoses (Margueron and Reinberg, 2010). DNA replication accompanies chromatin assembly, and the cooperation between these two processes has long been proposed to be important for the mitotic maintenance of epigenetic informat...
