Genome-Wide Identification, Expression Analysis under Abiotic Stress and Co-Expression Analysis of MATE Gene Family in Torreya grandis

The multidrug and toxin efflux (MATE) family participates in numerous biological processes and plays important roles in abiotic stress responses. However, information about the family genes in remains unclear. In this study, our genome-wide investigation identified ninety genes in , which were divided into five evolutionary clades. family members are located on eleven chromosomes, and a total of thirty exist in tandem duplication. The promoter analysis showed that most contain the cis-regulatory elements associated with stress and hormonal responses. In addition, we discovered that most genes responded to abiotic stresses (aluminum, drought, high temperatures, and low temperatures). Weighted correlation network analysis showed that 147 candidate transcription factor genes regulated the expression of 14 genes, and it was verified through a double-luciferase assay. Overall, our findings offer valuable information for the characterization of the gene mechanism in responding to abiotic stress and exhibit promising prospects for the stress tolerance breeding of .
