Hydrogen sulfide(H_2S),a signaling gasotransmitter,can promote flowering,a process that could be related to FLOWERING LOCUS C(FLC) in our previous experiments.Four FLC homologs have been reported in Brassica rapa. In the current study,we explored the spatiotemporal expression patterns of BrFLC homologs under H_2S treatment in Chinese cabbage to not only determine the differentiation of FLC homologs,but also analyze the effect of H_2S on their expression.The expression patterns of BrFLC1, 2 and 3 were consistent with that of AtFLC,whereas there were no significant changes in the expression of BrFLC5. BrFLC1 was expressed almost exclusively in leaves and cotyledons,whereas BrFLC2 was detected in various development stages. There was no noticeable change in BrFLC3 and 5 in the tissues examined, although BrFLC3 always showed the highest expression. Overall,BrFLC expression was slightly downregulated following exogenous H_2S treatment,with a minimum accumulation of BrFLC2 in leaves. Thus,H_2S appears to be able to regulate the downstream genes of BrFLCs to varying degrees and the variation in the expression patterns of downstream genes could be the result of the level of S-sulfhydration of H_2S and the functional diversity of the BrFLCs.So H_2S could have a place in regulating the expression of BrFLCs.
