Comparative genomic analysis of superoxide dismutase (SOD) genes in three Rosaceae species and expression analysis in Pyrus bretschneideri.

ABSTRACT: Superoxide dismutases (SODs) are antioxidant enzymes that play a critical role in the polymerization of lignin monomers. Although current research has indicated that SODs are involved in plant growth and development, information on SODs in pear (Pyrus bretschneideri) and their function in lignin formation is scarce. In this study, 25 SODs, containing three kinds of plant SODs (Cu/Zn-SODs, Mn-SODs, and Fe-SODs), were identified from three Rosaceae species, and 11 of these genes were found in pear. According to the evolutionary analysis, the genes were divided into four subgroups, the division of which is consistent with the intron-exon and conserved motif analyses. These PbSODs were randomly scattered across 7 chromosomes. We have analysed the conserved domains a
