Abstract
Superoxide dismutase (SOD) enzymes form the first line of plant protection against reactive oxygen species (ROS) accumulation in cells. In this study, we recognised 14 AvSOD genes in the hexaploid oat (Avena sativa) genome, including nine AvCSDs, three AvFSDs, and two AvMSDs. Phylogenetic analysis revealed that AvSOD genes from oat and different other monocotyledonous and dicotyledonous plant species were clustered into two different groups based on the metallic binding domain. The predicted 3D protein structures revealed comparable conserved AvSOD protein configuration within groups. Interestingly, different hormonal and light-responsive cis-elements were identified in the promoters of AvSOD genes. Gene ontology annotation results validate the AvSODs role such as response to contrasting stress stimuli (ozone, light intensity, UV-B, metallic stress…), metal-ion binding activities, cellular oxidant detoxification activity, and different other cellular components. Expression profiling by real time quantitative PCR showed that 12 genes (AvCSD1, AvCSD2, AvCSD3, AvCSD4, AvCSD5, AvCSD6, AvCSD7, AvFSD1, AvFSD2, AvFSD3, AvMSD1, and AvMSD2) were strongly upregulated in response to different hormones (abscisic acid and salicylic acid) and/or abiotic stress (salinity, cold, and drought) treatments. Our data provides more knowledge of SOD genes in plants and information for advanced functional analyses of this antioxidant gene family in oat.
