In silico identification and expression analysis of superoxide dismutase (SOD) gene family in Medicago truncatula.

ABSTRACT: Superoxide dismutase (SOD) proteins are crucial antioxidant enzymes that play critical roles in plant growth, development, and response to various abiotic stresses. The SOD gene family has been characterized in various plant species, but not in Medicago truncatula yet. Here, a total of 7 MtSOD genes were first identified from the whole genome of M. truncatula, including 1 MnSOD, 2 FeSODs, and 4 Cu/ZnSODs, which are unevenly distributed in five out of the eight chromosomes. Phylogenetic analysis showed that SOD proteins from M. truncatula and other plant species could be classified into two main categories (Cu/ZnSODs and Fe-MnSODs), which could be further divided into eight subgroups, and members within the same subgroup tended
