**5. Conclusions**

Recently, an increasing number of *VQ* genes in different plants were analyzed in genome-wide characterization and evolutionary studies. However, there is little functional information regarding *VQ* genes in the woody plants. Our research showed an overall picture of *EgrVQ* genes, displaying the genome-wide identification, characterization, and expression of *EgrVQ* genes under various stressors. The results verified that the *EgrVQ* genes family either positively or negatively regulated multiple responses, including biotic and abiotic stressors. In addition, this study will provide a theoretical basis for further study of the mechanism of the stress resistance mechanism of the *VQ* gene family and indicated that most of the *VQ* genes participate between the process of biotic and abiotic stress resistance of *E. grandis*.
