Effect of leghemoglobin A gene expression from soybean on tobacco plant growth and antioxidant state under damaging action of cadmium

Effect of leghemoglobin A gene expression from soybean on tobacco plant growth and antioxidant... Transgenic tobacco (Nicotiana tabacum L. plants, cv. Samsun) bearing the gene for soybean (Glycine max (L.) Merr.) leghemoglobin A under the control of 35S CaMV promoter were produced. The effects of this gene expression on tobacco growth and respiration, MDA content, and also activities of catalase and guaicol peroxidase were studied. The growth rate of transformed plant was reduced, respiratory losses were increased, and lipid peroxidation was substantially suppressed. In plants expressing the laghemoglobin A gene, the negative effects of toxic cadmium concentrations on growth parameters and plant oxidative status were weakened. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

Transgenic tobacco (Nicotiana tabacum L. plants, cv. Samsun) bearing the gene for soybean (Glycine max (L.) Merr.) leghemoglobin A under the control of 35S CaMV promoter were produced. The effects of this gene expression on tobacco growth and respiration, MDA content, and also activities of catalase and guaicol peroxidase were studied. The growth rate of transformed plant was reduced, respiratory losses were increased, and lipid peroxidation was substantially suppressed. In plants expressing the laghemoglobin A gene, the negative effects of toxic cadmium concentrations on growth parameters and plant oxidative status were weakened.
