This study aims to clone the FmJZ1 gene and clarify its response model under low temperature and NaCl stresses and its hormone-induced transcriptional expression characteristics . The FmJAZ1 gene of Fraxinus mandshurica was obtained by gene cloning. The sequence was analyzed by bioinformatics software and phylogenetic tree was constructed.Spatiotemporal expression specificity of Fraxinus mandshurica FmJAZ1 gene was analyzed. Samples of root, stem, leaf, bud, male flower, female flower and seedwere taken in May, June, July, August, and September respectively for plants of Fraxinus mandshurica under low temperature stress (4℃) salt stress (NaCl solution), or treated with hormone signal induction of abscisic acid (ABA), gibberellin (GA3), auxin (IAA), jasmonate (JA), and salicylic acid (SA), The treated materials were then subjected to fluorescence quantitative analysis,The full length nucleotide sequence of 684 bp was cloned in this experiment, Bioinformatics software analysis showed that JZA1 gene had a complete open reading frame, encoding 227 amino acids. JAZ1 protein did not contain signal peptide, it was not a transmembrane protein, and it was an unstable hydrophilic protein. The spatial expression of FmJAZ1 gene was the highest in stem, and the temporal expression was the highest in August. The expression level of FmJAZ1 gene was higher at 6 h and 24 h after low temperature treatment. and higher 24 h after NaCl treatment, with the response to low temperature stress faster than that to salt stress. The expression level of FmJAZ1 gene changed significantly with time after the treatments hormone signal induction, and the expression pattern of FmJAZ1 gene was analyzed for low temperature, NaCl stress and hormone induction treatments. The expression change of FmJAZ1 gene was 77.3 times higher than that of control group at 3 h after GA3 treatment. FmJAZ1 gene fully responded to abiotic stresses and hormone signal induction, with JAZ protein acting as a bridge and playing an important role in the responses at protein and gene levels.
