The CCCH(C3H) transcription factor is an important transcription factor in plants in the process of plant development, hormone regulation and under stress. Rose is one of the most important commercial flower crops worldwide. However, there are few reports about the C3H gene of rose and Rosa chinensis Jacq. The reference genome sequence becomes a valuable source of data for the C3H genes in rose (RcC3Hs). We identified 31 encoding members in total, which were distributed on seven chromosomes and clustered into 11 subgroups in R. chinensis. Each subgroup has similar group-specific features including motifs, gene structure, cis-acting elements and collinearity in R. chinensis and two other species (Arabidopsis thaliana and Oryza sativa L). The RcC3Hs' tissue-specific expression by quantitative real-time PCR (qRT-PCR) showed that the expression of RcC3Hs was higher in roots and leaves compared with other tissues. These results provide a theoretical basis for the follow-up exploration of the functions of RcC3Hs and the molecular breeding of rose.
