“…Vernalization down regulates the expression of FLC and maintaining this repression requires epigenetic regulation mediated by VERNALIZATION 2 (Accession number AF284500), a gene with similarity to the polycomb group of proteins [42]. The levels of FLC are crucial for the vernalization response and the interaction between FCA (Accession number Z82992) and FY (Accession number NM_121351) appears to regulate FLC mRNA 3 0 end formation providing a fine-tuning mechanism [43].…”

“…Because FLC is a flowering repressor, the gene which is upregulated by DNA demethylation is not FLC itself. The gene(s) upstream of FLC, such as VERNALIZATION1 (VRN1), VERNALIZATION2 (VRN2) or VERNALIZATION INSENSITIVE3 (VIN3) (Gendall et al 2001, Levy et al 2002, Sung and Amasino 2004, may be upregulated by DNA demethylation.…”

Treatment with 5-azacytidine, a DNA demethylating reagent, induced flowering in Perilla frutescens (L.) Britton var. crispa (Thunb. ex Murray) Decne. ex L. H. Bailey, an absolute short-day plant under long days. The 5-azacytidine treatment induced slight suppression of vegetative growth but had no obvious effect on any other phenotypes. The Southern hybridization analysis of the genomic DNA isolated from the leaves of 5-azacytidine-treated plants and digested with restriction enzyme, methylation-insensitive Msp I or methylation-sensitive Hpa II with P. frutescens 25S-18S rDNA intergenic spacer probe indicated that the 5-azacytidine treatment caused demethylation of the genomic DNA. The 5-azacytidine-induced flowering was delayed as compared with the short day-induced flowering. Flowers were formed even at the lower nodes which had not been directly treated with 5-azacytidine. The results suggest that DNA demethylation induced flowering by inducing the production of a transmissible flowering stimulus in P. frutescens.

“…Note that the flowering repressor gene FLC is significant up-regulated in sdr6 ( Figure 5). However, expression levels of key components CO and GI in the photoperiod pathway; SPY in the GA pathway (Tseng et al 2004); and VRN2 in the vernalization pathway (Gendall et al 2001;Levy et al 2002) were not significantly different from the wild-type and sdr6/SDR6 plants. These results suggested that the autonomous pathway is compromised in sdr6 plants, which led to later flowering when compared with the wild-type.…”

Identification of flowering-time related genes in Arabidopsis thaliana has very important and meaningful to understand the regulation mechanism of the flowering-time. One late flowering mutant plant which displays a delayed transition to flowering was obtained from the Arabidopsis T-DNA insertion mutant library. SDR6, which encodes a short-chain dehydrogenase/reductase containing a NAD(P)-binding domain in Arabidopsis, has been identified as a novel flowering-time gene in Arabidopsis by further analyzing of SDR6 complementing plants. The sdr6 plants displayed later flowering than wild-type plants both in long and short days, but flowered later in short day than in long day. The flowering-time of SDR6 complementing plants is similar to that of wild-type plants. The late-flowering phenotype of sdr6 plants was reversed by gibberellin and vernalization treatments, which is similar to those of several mutants in the autonomous pathway. Compared with the wild-type, expression levels of FLC, LD, FVE, and SOC1 genes, key components of the autonomous pathway, were significantly altered in sdr6 mutants. However, expression levels of the key genes in the photoperiod, gibberellin, and vernalization pathways were not obviously different. Therefore, this gene may be involved in the autonomous flowering pathway to regulate the Arabidopsis flowering.
