Nickel even though recognized as a trace element, its metabolism is very decisive for certain enzyme activities, maintaining proper cellular redox state and various other biochemical, physiological and growth responses. Study of the aspects related with uptake, transport and distributive localization of Ni is very important in various cellular metabolic(More)
INTRODUCTION This study was hypothesized that salicylic acid elevates the level of antioxidant system that will protect plants from the stress generated by nickel and/or salinity. MATERIALS AND METHODS Seeds of Brassica juncea were sown in sand amended with NiCl(2) (100 mg kg(-1)) and/or 15-day-old seedlings supplied for 3 days with NaCl (150 mM) and were(More)
The objective of this study was to establish relationship between boron induced oxidative stress and antioxidant system in Vigna radiata plants and also to investigate whether brassinosteroids will enhance the level of antioxidant system that could confer tolerance to the plants from the boron induced oxidative stress. The mung bean (V. radiata cv. T-44)(More)
Brassinosteroids have been extensively used to overcome various abiotic stresses. But its role in combined stress of salt and excess copper remains unexplored. Seeds of two cultivars (Rocket and Jumbo) of Cucumis sativus were grown in sand amended with copper (100 mg kg(-1)), and developed seedlings were exposed to salt stress in the form of NaCl (150 mM)(More)
The objective of this study was to establish relationship between manganese-induced toxicity and antioxidant system response in Brassica juncea plants and also to investigate whether brassinosteroids activate antioxidant system to confer tolerance to the plants affected with manganese induced oxidative stress. Brassica juncea plants were administered with(More)
Brassinosteroids (BRs) have been implicated to overcome various abiotic stresses, and low temperature stress poses a serious threat to productivity of various horticultural crops like tomato. Therefore, a study was conducted to unravel the possible role of BRs in conferring alleviation to low temperature stress in Lycopersicon esculentum. Twenty-day-old(More)
The aim was to explore the responses of varied doses of manganese in mustard plants and also to test the proposition that salicylic acid induced up-regulation of antioxidant system which protect photosynthetic apparatus. Seeds were sown in pots and allowed to germinate under natural environmental conditions. At 10 days stage, soils in the pots were enriched(More)
Among the compatible solutes, glycine betaine (GB) is particularly an effective osmolyte against abiotic stress. Metabolic acclimation of GB is regarded as a basic strategy for the protection and survival of plants in harsh environmental conditions. Plant species vary in their capacity to synthesize GB. Some plants, such as spinach and barley, accumulate(More)
The objective of this study was to explore the response of 24-epibrassinolide to improve the biological yield of Ni-tolerant and Ni-sensitive varieties of Vigna radiata and also to test the propositions that 24-epibrassinolide induced up-regulation of antioxidant system protects the efficiency of V. radiata, grown under Ni-stress. Surface sterilized seeds(More)
