Abstract
As a plant-specific transcription factor, the vascular plant one-zinc-finger (VOZ) plays a crucial role in regulating various biological processes. In this study, a total of 17 VOZ genes in the Cucurbitaceae family were investigated using various bioinformatics methods. The 17 VOZ genes in Cucurbitaceae are distributed across 16 chromosomes. Based on the affinity of VOZ proteins to AtVOZ proteins, these 17 proteins were categorized into two groups: group I encompassed eight VOZ members, while group II comprised nine VOZ members. The expression profiles of CmoVOZs under various hormonal and abiotic stresses indicated that these genes were induced differentially by JA, ABA, GA, salt, and drought stress. Subsequently, CmoVOZ1 and CmoVOZ2 were found to be transcriptionally active, with the CmoVOZ2 protein being located mainly in the nucleus. Further experiments revealed that yeast cells expressing CmoVOZ2 gene showed increased tolerance to salt stress and drought stress. These results suggest that the VOZ gene family is not only important for plant growth and development but also that this mechanism may be universal across yeast and plants.
