REVEILLE (RVEs) transcription factors play an important role in regulating circadian clock, plant growth and development, and stress responses. While RVEs have been identified in various plant species, comprehensive genome exploration and analysis of RVEs in castor (Ricinus communisL.) have not been previously reported. In this study, we identified RcRVEs in the castor genome through sequence alignment and conducted an analysis encompassing gene structures, protein motifs, physicochemical properties, transcription patterns under cold stress, different tissues, and diurnal rhythm. A total of five RcRVEswere pinpointed in the castor genome. Evolutionary tree analysis categorized these RcRVEs into three distinct groups, implying that different RcRVEs may fulfill distinct biological functions. Furthermore, several abiotic stresses and hormone-responsive cis-acting elements were found in the promoters of the RcRVEs. RNA-sequencing (RNA-seq) analysis revealed that RcRVE1and RcRVE7were induced by cold stress and exhibited upregulation over time, indicating their involvement in regulating cold adaptation in castor plants. Five RcRVEshave notably higher expression levels in leaves compared to other tissues. The expression of all RcRVEsdisplayed diurnal rhythms under light/dark cycles. This study provides valuable insights into the potential functions of RcRVEs in regulating castor’s growth and development, and responses to cold stress. |
