In plants, CIII PRXs can reduce hydrogen peroxide to catalyze oxidation-reduction reactions, thereby affecting plant growth, development, and stress responses. To date, no systematic analysis of the CIII PRX gene family in litchi (<i>Litchi chinensis</i> Sonn.) has been documented, although the genome has been reported. In this study, a total of 77 CIII PRX (designated LcPRX) gene family members were predicted in the litchi genome to provide a reference for candidate genes in the responses to abiotic stresses during litchi growth and development. All of these <i>LcPRX</i> genes had different numbers of highly conserved PRX domains and were uInternational journal of molecular sciencesGenome-Wide Identification and Expression Analysis of the Class III Peroxidase Gene Family under Abiotic Stresses in Litchi (&lt;i&gt;Litchi chinensis&lt;/i&gt; Sonn.).PMC111720182022DZXHT0582023YFD2300805-4, 2023TS-2-3, 2022DZXHT058, 2022A0032022A0032023YFD2300805-42023TS-2-3Yang JXiang XChen RFan CLiu WfalseGenome-Wide Identification and Expression Analysis of the Class III Peroxidase Gene Family under Abiotic Stresses in Litchi (&lt;i&gt;Litchi chinensis&lt;/i&gt; Sonn.).Class III peroxidases (CIII PRXs) are plant-specific enzymes with high activity that play key roles in the catalysis of oxidation-reduction reactions.
