1Photosynthesis, Growth and Antioxidant Metabolism in Mustard (Brassica juncea L.) Cultivars Differing in Cadmium Tolerance显示文摘Two mustard (Brassica juncea L. Czern and Coss.) cultivars, Pusa Jai Kisan and SS2 differing in cadmium (Cd) tolerance were treated with 0, 25 and 50 μmol L-1 Cd to study the physiological basis of difference in Cd tolerance. Cultivar SS2 (Cd sensitive) accumulated greater Cd in leaves than Pusa Jai Kisan (Cd tolerant). Further, SS2 also exhibited higher contents of thiobarbituric acid reactive substances (TBARS) and H2O2 and electrolyte leakage. However, the activities of antioxidant enzymes, catalase (CAT), ascorbate peroxidase (APX), dehydroascorbate reductase (DHAR), and glutathione reductase (GR) were higher in Pusa Jai Kisan than those in SS2. Contrarily, the activity of superoxide dismutase (SOD) was higher in SS2 than that in Pusa Jai Kisan and was the greatest at 25 μmol L-1 Cd. Treatment of 25 μmol L-1 Cd induced the maximum activity of enzymes. However, the activity of GR increased up to 50 μmol L-1 Cd in both the cultivars. The non-enzymatic antioxidants ascorbate (AsA) and glutathione (GSH) were higher in Pusa Jai Kisan than that in SS2, whereas dehydroascorbate (DHA) and oxidized glutathione (GSSG) were higher in SS2. Photosynthesis and growth were adversely and maximally decreased by 50 μmol L-1 Cd treatment in both the cultivars, but SS2 exhibited greater reductions. The protection of photosynthesis and growth and lesser reduction in Pusa Jai Kisan were associated with its capacity to restrict accumulation of Cd in leaves resulting in lower level of TBARS and H2O2 and electrolyte leakage. Moreover, Pusa Jai Kisan exhibited efficient antioxidant metabolism for removal of Cd-induced reactive oxygen species.Noushina Iqbal Asim Masood Rahat Nazar Shabina Syeed Nafees A Khan 2010Agricultural Sciences in China2010,9,4:8
2Efficient Algorithm for Prolonging Network Lifetime of Wireless Sensor Networks显示文摘One of the fundamental design challenges in designing a Wireless Sensor Network (WSN) is to maximize the network lifetime,as each sensor node of the network is equipped with a limited power battery.To overcome this challenge,different methods were developed in the last few years using such techniques as network protocols,data fusion algorithms using low power,energy efficient routing,and locating optimal sink position.This paper focuses on finding the optimal sink position.Relay nodes are introduced in conjunction with the sensor nodes to mitigate network geometric deficiencies since in most other approaches the sensor nodes close to the sink become heavily involved in data forwarding and,thus,their batteries are quickly depleted.A Particle Swarm Optimization (PSO) based algorithm is used to locate the optimal sink position with respect to those relay nodes to make the network more energy efficient.The relay nodes communicate with the sink instead of the sensor nodes.Tests show that this approach can save at least 40% of the energy and prolong the network lifetime.Md Nafees Rahman M A Matin 2011Tsinghua Science and Technology2011,16,6:6
3Fungi as chemical industries and genetic engineering for the production of biologically active secondary metabolites显示文摘Fungi is somewhere in between the micro and macro organisms which is a good source of producing biologically active secondary metabolites.Fungi have been used as tool for producing different types of secondary metabolites by providing different nutrients at different laboratory conditions.The fungi have been engineered for the desired secondary metabolites by using different laboratory techniques,for example,homologous and heterologous expressions.This review reported how the fungi are used as chemical industry for the production of secondary metabolites and how they are engineered in laboratory for the production of desirable metabolites:also the biosynthetic pathways of the bio-organic-molecules were reported.Abid Ali Khan Nafees Bacha Bashir Ahmad Ghosia Lutfullah Umar Farooq Russell John Cox 2014Asian Pacific Journal of Tropical Biomedicine2014,4,11:5
