- Abstract
The transcription factor family RELATED to ABSCISIC ACID INSENSITIVE3 (ABI3)/VIVIPAROUS1(VP1) (RAV) is a plant-specific group of transcription factors that only contain a conserved B3 DNA binding domain or both their own B3 and APETALA2 (AP2) domains belonging to the B3 superfamily, which is vital for plant growth, development, and stress response. Although genome-wide characterization and analysis of the RAV family genes have been conducted in some species, they have not been systematically reported in chrysanthemums. Here, we found six RAV family genes in the diploid Chrysanthemum seticuspe genome. Based on domain similarity and homology comparison analyses, RAV genes in Chrysanthemum were categorized into two clades: Class-I and Class-II. Conserved motif analysis revealed that all CsRAV proteins contained the B3 repression domain. An analysis of cis-acting elements suggested that CsRAV family genes may play parts in light, hormonal, abiotic stress, growth, and developmental processes. Furthermore, quantitative RT-PCR analysis validated that all six CsRAV genes responded to ethylene treatment, whereas the genes in the Class-I clade responded most significantly to ethylene. In summary, the above results provided a conceptual basis for further investigation into the functions of CsRAV genes in C. seticuspe.
