Comprehensive Analysis of the Catalase (CAT) Gene Family and Expression Patterns in Rubber Tree (Hevea brasiliensis) under Various Abiotic Stresses and Multiple Hormone Treatments.

ABSTRACT: Catalase (CAT) is one of the key enzymes involved in antioxidant defense systems and mainly scavenges H₂O₂ and plays a vital role in plant growth, development, and various adverse stresses. To date, a systematic study of the CAT gene family in rubber tree has not been reported. In this study, five HbCAT gene family members were identified from the rubber tree genome, and these were mainly clustered into two subfamilies. Gene structure and motif analysis showed that exon-intron and motif patterns were conserved across different plant species. Sequence analysis revealed that HbCAT proteins contain one active catalytic site, one heme-ligand signature sequence, three conserved amino acid residues (His, Tyr, and Asn), and one peroxisome-targeting signa
