Insights into the Superoxide Dismutase Gene Family and Its Roles in Dendrobium catenatum under Abiotic Stresses.

ABSTRACT: Dendrobium catenatum is a member of epiphytic orchids with extensive range of pharmacological properties and ornamental values. Superoxide dismutase (SOD), a key member of antioxidant system, plays a vital role in protecting plants against oxidative damage caused by various biotic and abiotic stresses. So far, little is known about the SOD gene family in D. catenatum. In this study, eight SOD genes, including four Cu/ZnSODs, three FeSODs and one MnSOD, were identified in D. catenatum genome. Phylogenetic analyses of SOD proteins in D. catenatum and several other species revealed that these SOD proteins can be assigned to three subfamilies based on their metal co-factors. Moreover, the similarities in conserved motifs and gene structures in the same subfamily cor
