[47]. Abundant proteins identified in both ecotypes included enzymes of ascorbate-glutathione cycle like ascorbate peroxidase and dehydroascorbate reductase and Cu/Zn-containing superoxide dismutase (SOD). However, methionine sulfoxide reductase or fruit-ripening protein E4 was identified specifically in ...
[0048] In addition, the expression vectors preferably contain one or more selectable marker genes to provide a phenotypic trait for selection of transformed host cells such as dihydrofolate reductase or neomycin resistance for eukaryotic cell culture, or such as tetracycline or ampicillin resistance in ...
