In Vitro Effects

This paper deals with the in vitro effects of brassinosteroids (BRs) on growth in the form of multiple shoots, chlorophyll content, Hill reaction activity (HRA), activities of catalase (CAT), peroxidase (POX), polyphenol oxidase (PPX), and ascorbate peroxidase (APX) in Arachis hypogaea L. genotypes (M-13 and PBS24030). In vitro impact of BR on shoot multiplication potential was found to be the best at 1 mL L−1 with BA (3 mg L−1) in both the cultivars. Flowering was observed in PBS24030 on the medium containing 2.0 mL L−1 BR with 3 mg L−1 BA. Rhizogenesis was noticed in the presence of BR alone. Total chlorophyll content and HRA were highest at 2.0 mL L−1 with BA in M-13 and 1.0 mL L−1 with BA in PBS24030. Antioxidant enzyme activities were increased in the presence of BR whether alone or in combination with BA in both the cultivars. However, progressive decline was observed in case of MDA content. The results obtained in the study clearly indicated not only the in vitro establishment of groundnut cultivars in the presence of BR alone and in combination with BA but also its effect on various growth promotory physiological parameters.

Calcium Oxalate Urolithiasis

Gokshuradi Yog (GY)is a polyherbal ayurvedic formulation used traditionally for several decades in India for the treatment of urolithiasis. The aim of the present study was to determine the underlying mechanism ofGYaction in the management of calcium oxalate urolithiasis. The effect ofGokshuradi polyherbal aqueous extracts(GPAEs) was studied on various biochemical parameters involved in calcium oxalate formation by employingin vitroandin vivomethods.GPAEexhibited significant antioxidant activity against 1, 1-diphenyl-2-picrylhydrazyl free radical and inhibited lipid peroxidation in thein vitroexperiments. The rat model of urolithiasis induced by 0.75% ethylene glycol (EG) and 1% ammonium chloride (AC) in water caused polyuria, weight loss, impairment of renal function, and oxidative stress and decreased antioxidant enzyme activities in untreated control groups. However,GPAE-(25, 50, and 100 mg/kg) treated groups caused diuresis accompanied by a saluretic effect and revealed significant increase in antioxidant enzyme activities along with decreased oxalate synthesizing biochemical parameters at higher doses. This study revealed the antiurolithic effect ofGPAEmediated possibly through inhibiting biochemical parameters involved in calcium oxalate formation, along with its diuretic and antioxidant effects, hence supporting its use in the treatment of calcium oxalate urolithiasis.

Sesame Genotypes

An experiment was conducted under pot culture to investigate physiological responses as well as antioxidative enzymes activities that may lead to select sesame genotype (s) which were more waterlogging tolerant at vegetative stage. Four sesame genotypes viz. BD-6980, BD- 6985, BD-6992 and BD-7012 were grown under waterlogged (at vegetative stage) and control (no waterlogged) conditions. Plant height, root length, root volume, root dry weight and leaf area per plant in all the four sesame genotypes significantly decreased due to waterlogging at vegetative stage in comparison to controlled condition. Higher SPAD value (Soil and Plant Analyzer Development) and specific leaf mass were recorded in waterlogged plant than controlled plant during waterlogging period but reverse was the case during recovery period. All the genotypes showed positive indices of waterlogging tolerance in terms of better performance of root, stem, leaf and petiole. Among the genotypes, BD 6980 showed higher waterlogging tolerance in all the components followed by BD 6985. Malondialdehyde (MDA) content was found higher in waterlogged plant of all the four sesame genotypes in both waterlogging period and recovery period than the controlled plant. Antioxidant enzyme activities like Peroxidase (POD), Catalase (CAT), Ascorbate peroxidase (APX), Glutathione peroxidase (GPX) and Superoxide dismutase(SOD) were inconsistent in the present study but most of the antioxidant enzyme activities showed an increasing trend in waterlogged plant than that of control plant in all the genotypes. Comparatively low amount of MDA content and high antioxidant activities of sesame genotype BD 6980 is considered as highly tolerant to waterlogging and other three genotypes are moderately tolerant under water logging condition.SAARC J.

Hyperaccumulator Plant

Lettuce (Lactuca sativa) is one of the most common green leafy vegetables, which is widely cultivated all over the world, but extremely sensitive to cadmium (Cd) contaminated in soil. The effects of three hyperaccumulator plants straw (Solanum nigrum, Bidens pilosa and Galinsoga parviflora) on the antioxidant enzyme activities and osmotic regulators and malondialdehyde (MDA) content under Cd stress were studied by pot culture. Compared with no straw, three kinds of hyperaccumulator straw of S. nigrum straw, B. pilosa straw and G. parviflora straw increased the content of soluble protein and proline in lettuce, the activity of peroxidase (POD) and catalase (CAT) in lettuce was also increased, and the content of MDA was decreased. The stress resistance of lettuce was improved and the toxicity of Cd to lettuce was alleviated by using three kinds of hyperaccumulator plant straw.

Pal Activity

Jatropha curcas embryos were grown in vitro to observe the effects of lead on cotyledon responses. The cotyledon biomass increased initially and then decreased with increasing lead concentration. The SOD activity increased gradually up to 200 μM and then decreased. The POD activity showed a similar trend. The CAT activity was increased at all lead concentrations, the highest activity being observed at 200 μM. However, the PAL activity was inhibited significantly except for 100 μM. Anaylsis by electrophoresis suggested a significant correlation between lead concentration and patterns of SOD, POD and CAT isoenzymes, and these results were consistent with changes of the antioxidant enzyme activities as assayed in solution.
