Abstract Caffeic acid‐3‐ O ‐methyltransferase (COMT) serves as the final pivotal enzyme in melatonin biosynthesis and plays a crucial role governing synthesis of plants. This research used bioinformatics to analyze phylogenetic relationships, gene structure, promoter cis ‐acting elements upland cotton COMT family members， which it identified key GhCOMT33D promote responding Cd 2+ stress. After silencing through virus‐induced (VIGS), seedlings showed less resistance Under stress, content silenced plants significantly decreased, while ROS, MDA, proline accumulated plant cells. The stomatal aperture leaves was reduced, hindering normal photosynthesis, leading withering yellowing, epidermal cells becoming twisted deformed, with large number gaps appearing. non‐silenced had higher were better condition, providing important evidence for further on how enhances its regulatory mechanisms.
