Proteomics in conjunction with morphological, physiological and biochemical variables has been employed for the first time to unravel survival strategies of the diazotrophic cyanobacterium Anabaena sp. PCC7120 under Arsenic (As) stress. Significant reduction in growth, carbon fixation, nitrogenase activity and chlorophyll content after 1 day (1d) and(More)
Present study is the first to explore physiological, biochemical and molecular changes in the medicinal plant Artemisia annua under arsenic (As) stress. A. annua grown hydroponically in a nutrient solution was spiked with increasing doses of As (0, 1,500, 3,000 and 4,500 μg l(-1)) for 7 days. Plants accumulated As in a dose dependent manner with(More)
Present study was undertaken to investigate if short-term UV-B (4.2 kJ m(-2) day(-1)) and UV-C (5.7 kJ m(-2) day(-1)), pre-treatments can induce artemisinin biosynthesis in Artemisia annua. Twenty-one day old Artemisia seedlings were subjected to short-term (14 days) UV pre-treatment in an environmentally controlled growth chamber and then transplanted to(More)
This paper constitutes the first report on the Alr1105 of Anabaena sp. PCC7120 which functions as arsenate reductase and phosphatase and offers tolerance against oxidative and other abiotic stresses in the alr1105 transformed Escherichia coli. The bonafide of 40.8 kDa recombinant GST+Alr1105 fusion protein was confirmed by immunoblotting. The purified(More)
Pea rust caused by Uromyces fabae (Pers.) de-Bary is a major problem in warm humid regions causing huge economic losses. A mapping population of 136 F6:7 recombinant inbred lines (RILs) derived from the cross between pea genotypes, HUVP 1 (susceptible) and FC 1 (resistant) was evaluated in polyhouse as well as under field conditions during two consecutive(More)
This paper provides the first proteomic evidence of arsenic (As) tolerance and interactive regulatory network between primary and secondary metabolism in the medicinal plant, Artemisia annua. While chlorophyll fluorescence and photosynthetic rate depicted mild inhibition, there was a significant enhancement in PSI activity, whole chain, ATP, and NADPH(More)
Pea rust caused by Uromyces fabae (Pers.) de-Bary is an important disease in subtropical regions of the world. The use of partial resistance or slow rusting is an important strategy for developing varieties having durable rust resistance. A mapping population of 136 F6:7 Recombinant Inbred Lines (RILs) derived from the cross HUVP 1 × FC 1 was evaluated for(More)
Pea rust is a devastating disease of peas especially in the sub-tropical regions of the world and greatly influenced by the environmental conditions during disease development. Molecular markers associated with pea rust resistance would be useful in marker assisted selection (MAS). Utility of molecular markers associated with the pea rust resistance were(More)
BACKGROUND The treatment for MDR TB is quite prolonged and associated with adverse effects and hence costly. AIM The aim of study was to study the side-effects of reserve line drugs developing in initial seven days of starting therapy, so as to weigh the need for admission for initiation of treatment against heavy economic burden by admission of huge(More)
Ten recombinant inbred lines (RILs) of pea were selected, on the basis of rust (Uromyces fabae) reaction under screenhouse conditions and molecular makers associated with rust resistance, to study the association of lignification and early abortive fungal colonies in response to attack of U. fabae. The present investigation indicated that partial resistance(More)
