Proteomics and photosynthetic apparatus response to vermicompost attenuation of salinity stress Vicia faba leaves

Abstract Crop production and growth are severely affected by salt stress. Nevertheless, the bio-fertilizer vermicompost (VC) can be participated as a potent inhibitor of salinity on plant crop regulating photosynthetic efficiency. We investigated effect VC performance salt-stressed broad bean ( Vicia faba L. Aspani cultivar). Seeds were grown in soil mixture; clay sand ratio 1:2 volume with five different volumetric ratios VC; 0, 2.5, 5, 10 15% irrigated either water and/or 200 mM NaCl. Leaf area, Na K contents, chlorophylls, photosystem II efficiency, Rubisco content, soluble sugars, chloroplasts’ organization proteomics analyzed. The imposed stress decrease leaf chlorophyll maximum quantum efficiency (Fv/Fm), increase sugars damage chloroplasts organization. Salinity upregulated glucose-1-phosphate adenylyl transferase, ribulose bisphosphate carboxylase large subunit chloroplastic peptidyl-prolyl cis–trans isomerase. increased , b carotenoids, II, improving degeneration thylakoid lamellae lessening plastoglobuli number membranes major benefits attained treatments under Analysis proteomic revealed that ferredoxin–NADP reductase, plastocyanin, polyphenol oxidase, isomerase, alpha-glucan phosphorylase H isozyme maturase expression results suggest controls protein at level transcriptional translational which may conserve components prevent salt-induced harmful effects plants.
