Physiological Studies on the Role of Cyanobacteria in Ameliorating the Toxic Effects of Copper in Trigonella foenum gracum: Thesis Abstract

Thesis Abstract A greenhouse experiment was conducted in order to assess the possible effects of Nostoc muscorum (2 g/ kg soil fresh pellets) on growth and some metabolic activities Trigonella foenum gracum at 30, 60 days yield under different concentrations CuSO4. Application a mixture with Cu significantly increased all parameters, photosynthetic pigments activity, soluble insoluble nitrogen 30 when compared their counterparts treatment. In addition, content K+, Ca2+, P3+ iron were except for decrease level growth. On other hand, starch peptides decreased Moreover, activity both POD SOD reduced by applying having Cu. Biochemical analysis yielded seeds revealed that total carbohydrate, protein lipids increased, whereas alkaloids phenolics decreased. Mixing percentage unsaturated fatty acids control singly. Scanning SDS-PAGE gel indicated de novo synthesis two polypeptides molecular weight 44 67 KDa. Isozyme profile α β-esterase showed 3 isoforms esterase varied intensity thickening response treatments.
