Expression of FLOWERING LOCUS C and a frameshift mutation of this gene on chromosome 20 differentiate a summer and winter annual biotype of Camelina sativa.

ABSTRACT: The nature of the vegetative to reproductive transition in the shoot apical meristem of Camelina sativa summer annual cultivar CO46 and winter annual cultivar Joelle was confirmed by treating seedlings with or without 8 weeks of vernalization. True to their life cycle classification, Joelle required a vernalization treatment to induce bolting and flowering, whereas CO46 did not. In this study, whole genome sequence, RNAseq, and resequencing of PCR-amplified transcripts for a key floral repressor were used to better understand factors involved in the flowering habit of summer and winter biotypes at the molecular level. Analysis of transcriptome data indicated that abundance for one of the three genes encoding the floral repressor FLOWERING LOCUS C (FLC; Csa20 g015400) w
