棉花VOZ基因家族鉴定及GhVOZ1耐盐功能研究
Genome-wide Identification of VOZ Genes Family in Cotton and Study on Salt Tolerance Function of GhVOZ1
摘要
Abstract
The vascular plant one-zinc finger protein(VOZ)is a transcription factor specific to higher plants,which is involved in regulating plant growth and development,as well as responding to biotic and abiotic stresses.To identify the VOZ gene family of cotton and analyze the function of the GhVOZ1 gene under salt stress,the VOZ family in diploid and tetraploid cotton species was analyzed.The results showed that diploid and tetraploid cotton species contained 3 and 8 VOZ members,respectively,and the structures of most VOZs genes in Gossypium hirsutum and G.barbadense were highly conserved.GaVOZ1,GrVOZ1,GhVOZ1,GhVOZ5,GbVOZ1 and GbVOZ6 clustered together with several salt-tolerant genes,indicating that this group of VOZs had similar functions.The expression of GhVOZs was significantly upregulated under salt stress for 12 h.Among them,the expression levels of GhVOZ1 and GhVOZ5 were upregulated by nearly 7 times compared with the water control,suggesting that these 2 genes were important candidate genes involved in the response to salt stress.GhVOZ1 was localized in cytoplasm,and its overexpression in Arabidopsis thaliana could significantly enhance the salt tolerance of the plants.Above results provided reference for deeper understanding of the function of cotton VOZ genes under salt stress and offer new gene resources for molecular improvement of salt tolerance.关键词
