Findings from Central Salt and Marine Chemicals Research Institute Provide New Insights into Peroxidases [Ectopic over-expression of peroxisomal ascorbate peroxidase (SbpAPX) gene confers salt stress tolerance in transgenic peanut (Arachis ...]

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Enzymes and Coenzymes have been published. According to news reporting originating in Bhavnagar, India, by NewsRx journalists, research stated, "Peroxisomal ascorbate peroxidase gene (SbpAPX) of an extreme halophyte Salicornia brachiata imparts abiotic stress endurance and plays a key role in the protection against oxidative stress. The-cloned SbpAPX gene was transformed to local variety of peanut and about 100 transgenic plants were developed using optimized in vitro regeneration and Agrobacterium mediated genetic transformation method."

The news reporters obtained a quote from the research from Central Salt and Marine Chemicals Research Institute, "The T-0 transgenic plants were confirmed for the gene integration; grown under controlled condition in containment green house facility; seeds were harvested and T-1 plants were raised. Transgenic plants (T-1) were further confirmed by PCR using gene specific primers and histochemical GUS assay. About 40 transgenic plants (T-1) were selected randomly and subjected for salt stress tolerance study. Transgenic plants remained green however non-transgenic plants showed bleaching and yellowish leaves under salt stress conditions. Under stress condition, transgenic plants continued normal growth and completed their life cycle."

According to the news reporters, the research concluded: "Transgenic peanut plants exhibited adequate tolerance under salt stress condition and thus could be explored for the cultivation in salt affected areas for the sustainable agriculture."
