Genome-Wide Identification of the Gene Family in L. and Response to Drought Stress.

Caffeic acid O-methyltransferase (), as a multifunctional enzyme involved in various physiological and biochemical processes in lignin metabolism, plays an important role in a plant's response to stress. In this study, we isolated family members from the walnut genome by bioinformatics and analyzed their physicochemical properties and their expression under drought stress to provide gene resources for drought resistance in walnut. The results showed that 33 genes were identified from walnuts and distributed on different chromosomes.
