Subject: Origin and source characterization of methane in the shallow –water environment of Southern Lake Tanganyika rift basin, Tanzania
Keywords: Biogenic origin, isotopic composition, methane, molecular characterization, shallow-water environment
Abstract: Lake Tanganyika , located in the western part of Tanzania between 3°S and 9°S lat, harbours hydrocarbon and southern shallow-water environment. In this study, a geochemical analysis of stable carbon and hydrogen isotopes and interpretation of individual gas molecular composition were done in order determine the origin and composition of the naturally occurring hydrocarbon gases in Tangankiya Basin. Nitrogen, a non-hydrocarbon gas is a major component (76.69%-78-31%) by volume percentage followed by methane (11.68%-12.94%) and other higher hydrocarbons (0.16%-1.63%).The isotopic composition of carbon,δ13C1 and hydrogen δDC1 ranges from -65.32%0 to -65.81% and -272.5% to -275.9%o respectively. The isotopic compositions of ethane (δDC2 =-36.7%o o -35.2%o) and propane (δDC3 =-31.3%o to -27.5%o) reflect the thermogenic origin of these higher of carbon and hydrogen isotope ratios and δD-values, methane gas falls in the biogenic origin category and formed by carbon dioxide reduction. The isotopic composition of CO2 varies between -86%o and -3.4%o.CO2 reduction is also regarded as a mechanism of biogenic methane formation based on carbon isotope fractionation factors (greater than 0.16).

Keywords: Drought, Oryza sativa L., potassium, root plasticity
Abstract: In plants, roots sense the availability of potassium and water .This study examined the influence of potassium availability on root architecture and above-ground growth under water-deficit condition. We found that the growth of rice seedlings was further reduced by low potassium under water stress. We noted considerable reduction in the root projected area, maximum width and width-to-depth ratio. Furthermore, high potassium supply helped in sustaining the root top and bottom angles and prevented root steepness under mild water stress. However, high potassium availability did not result in better seedling growth. Root steepness was more influenced by water than potassium levels under severe water stress.

Subject: Prediction of potential drug targets for cutaneous leishmaniasis by Leishmania major and Leishmania tropica: a quantitative proteomics and bioinformatics approach
Keywords: Cutaneous leishmaniasis, Leishmania tropica, Leishmania major, protein interaction network, quantitative proteomics
Abstract: Leishmania spp. cause life-threatening infectious diseases which affect universal health. Novel treatments for leishmaniasis are crucially needed since those available are limited by emerging drug-resistant species, low efficacy and side effects. In this study, we have employed a quantitative shotgun proteomics and bioinformatics method to identify differentially expressed proteins (DEPs) between Leishmania major and Leishmania tropica and to detect novel potential drug targets for cutaneous leishmaniasis, which may aid in the future drug discovery process. A total of 57 proteins were differentially expressed between the studied species. Based on KEGG pathway analysis, the more upregulated proteins in L.major are clearly related to proteasome and metabolic pathways. In L.tropica , most of the upregulated proteins are related to the metabolic pathways and carbon metabolism. According to gene ontology analysis based on biological process, the upregulated proteins mainly participated in translation and carbohydrate metabolism in L.tropica and L.major respectively. We have constructed a protein –protein interaction network that is common for the two species .We detected the top 10 potential targets for drug design by topology analysis of the proteins network. Additional in vivo studies are needed to confirm these targets. We have identified several new DEPs between the species which would help in the understanding of pathogenesis mechanisms and offer potential drug targets and vaccine candidates. Analysis of the predicted protein network provides a catalogue of key proteins, which can be considered in future studies to be validated as druggable targets against cutaneous leishmaniasis.

Subject: Allelopathic potential and allelochemicas in different intercrops for weed management in rainfed cotton
Keywords: Allelochemicals, allelopathic potential, intercrops, rainfed cotton, relative neighbour effect.
Abstract: Allelochemicals released by plants serve as the primary defence by targeting the establishment of weeds and other plants. In this study, 12 different intercrops were assessed over five seasons for total phenol and terpenoid content. A detailed analysis on allelochemicals produced was also done using gas chromatography-mass spectrometry (GC-MS) to correlate with their weed suppression efficiency. Total phenol content of intercrops ranged from 6.5 to 17.6 mg g-1 tissue dry wt, with the highest value in carom followed by sorghum, sunhemp and marigold. Total terpenoid content of leaf extracts of the intercrops varied from 14.5 to 35.9 µg g-1 tissue dry wt, wherein pearl millet had maximum terpenoid content (35.9 µg g-1 tissue dry wt) followed by sunhemp and sesame. Analysis using GC-MS indicated the presence of some unique as well as common allelochemicals in the experimental intercrops. To correlate the abundance of these allelochemicals in the experimental intercrops. To correlate the abundance of these allelochemicals released from intercrops with their weed suppression competence, relative neighbour effect (RNE) value was determined for each intercrops. Positive RNE values for sunhemp, pearl millet and sesame indicate their efficiency in effectively reducing weed population than the other intercrops. Thus, intercrops with high phenolic, terpenoid and other allelochemicals specific to sunhemp, pearl millet and sesame can be correlated well with weed suppression as perceptible from their RNE values.

Keywords: Nowcasting, physical processes, rapid scan operations, severe weather conditions, weather monitoring
Abstract: In order to observe severe weather conditions during cyclones, thunderstorms, etc., IMAGER instruments on-board INSAT3D/3DR have been built with a flexible scanning feature known as ‘rapid scan mode’. Using this feature, the number of scan lines over a given coverage region and the number of repetitions of the selected region and the number of repetitions of the selected region can be programmed for scanning. Therefore, to understand the physical processes involved in convective clouds associated with severe weather phenomena, rapid scan of INSAT3DR mode is attempted. It has very high temporal resolution of approximately 4 min and 30 sec. The present study will help in better understanding of the physical processes of severe weather phenomena and in nowcasting .It will also help to improve the accuracy in the NWP model forecast through assimilation of radiances and atmospheric motion wind determined using rapid scan mode.

Abstract: Heavy metals are persistent in nature and toxic to all life forms. Increase in industrialization, urbanization and unsafe agriculture practices is constantly adding heavy metals pollution of water and soil. Considering the negative impacts of heavy metals on the environment, several strategies have been devised to remediate them. However, most of these have their own limitations. Bioremediation of metals by microorganisms is efficient, cost-effective and environment friendly method of metal detoxification. Microbes can utilize metal contaminants as their energy source and transform them to less toxic forms. When exposed to metals for a considerable period of time, microorganisms interact with them and become tolerant by developing resistance mechanism against them. Metal-microbe interactions can occur in several ways such as biosorption, bioleaching, bio mineralization, bioaccumulation and biotransformation. Study of these interactions is important to understand resistance mechanisms against metals which include barriers, efflux system, sequestration and reduction of metals. These mechanisms are encoded by the resistance genes localized in chromosomes and plasmids. Understanding resistance mechanisms against metals in microorganisms become crucial for devising strategies for bioremediation of metals.

Subject: Soil erosion and policy initiatives in India
Keywords: Conservation initiatives, land degradation, soil erosion
Abstract: Though soil erosion is a natural phenomenon, the rate of erosion has been increased 10 to 100 times because of land conversion ( e.g. land conversion from forest to agriculture ) and land management ( overgrazing , expansion of cultivation) .However, behind this land transformation some, socio-cultural and policy decision acts as drivers. Ancient humans had a good knowledge to prevent soil erosion through terracing even 4000 years ago. The decline of civilizations has been closely linked with the degradation o their resources particularly deforestation, accelerated soil erosion and the decline of crop yields. Historical evidences are crucial and provide alternative proxies about soil erosion in the past. Among the various factors, it is portrayed that natural situations, cultural traditions and socio-economic, and governance played a major role in the dynamics and rates of soil erosion in a long-term perspective. Ensuring harmony and keeping balance with nature is a great challenge in a democratic polity with a fast-expanding market economy.

Keywords: Climate resilience, indigenous landrace, nutritional security, wild crops
Abstract: Indigenous and wild crop resources play a significant role in food and nutrition security and are also important resources for sustainable food systems under climate change. Koraput district, Odisha is one of the agro-biodiversity hotspots in India dominated by tribal communities. The plant genetic resources of this region are the significance not only for the diversity, but also their consumption pattern. The present study aimed to chronicle the nutritional value of selected neglected and underutilized crop species of Koraput. Although these plant species are useful for poor and marginalized farmers, they are largely ignored by the scientific community, breeders and policymakers. Therefore, this study highlights the nutritional and climate-resilient traits of such species for conservation and further utilization. Mass consumption, commercialization and bioprospecting of these valuable resources would be the right step for ensuring food and nutritional security in future climate change scenarios.

Abstract: The recent development agenda in agriculture aims towards making the sector remunerative, competitive and sustainable through accelerating ongoing transformation and addressing the emerging challenges. The enactment of new farm Acts, 2020 has led to an intense debate with arguments both in favour and against their likely implications on farmers’ welfare and the agricultural sector .This article evidently examines the rationality of enacting new farm Acts, and discusses critical issues for their effective implementation and realizing the intended benefits. These Acts aim to create an ecosystem for efficient and competitive marketing and foster investment in post-production stages. Realization of indeed benefits requires strengthening of aggregating institution like farmer producer organizations, creating enabling conditions for competition between Agricultural Produce Marketing Committee (APMC) mandis and outside trade, and developing an effective market intelligence and price information system for efficient price discovery outside APMCs.

Abstract: The hydrogen economy is opportune for India because it has great potential for boosting her energy security and alleviating greenhouse gas (GHG) emissions. Hydrogen can be employed as a fuel in a variety of applications, including fuel-cell power generation and fuel-cell vehicles. It combusts cleanly, producing only water and can be used as a fuel in conventional internal combustion engines (ICEs) to generate mechanical or electrical power. The overall energy efficiency is higher than that of conventional ICEs. The efficiency of hydrogen ICE is ~38%, 8% higher than that of petrol ICE. The hydrogen fuel cell is 2-3 times more efficient than an ICE.

Keywords: Ethnomedicianl plants, ethnic groups, photochemical analysis, Thangal –Naga, traditional knowledge
Abstract: With a population of 4475 individuals, the Thangal-Naga of Manipur is one of the vulnerable schedule tribe groups in India. During the study, oral traditional knowledge for the treatment of ailments using wild medicinal plants by the ethnic group was documented. Forty-one ethnomedicinal plants from 40 genera and 28 families were reported during the semi-structured interviews of 70 locals. In total, 29 different ailments were treated using medicinal plants. Further, phytochemical analysis of 11 common medicinal plants revealed the presence of alkaloids, flavonoids, saponins, tannins, phenols, steroids, anthraquinones, coumarins, glycosides and terpenoids.

Subject: Biodegradation kinetics of acenaphthene by Sphingobacterium sp. Strain RTSB isolated from a petroleum –contaminated soil
Keywords: Acenaphthene, biodegradation, kinetic study, 1naphthoic acid, Sphingobacterium sp.
Abstract: Biodegradation metabolism was previously reported by a Gram-negative Sphingobacterium sp.strain RTSB. The degradation pathway was found to proceed involving the key intermediate 1-naphthoic acid and processed via trans-3-carboxy-2-hydroxybenzylidene-pyruvic acid to salicylic acid and catechol. The present article demonstrates the biodegradation kinetics of acenaphthene along with the fate of some of the major metabolites, 1-naphthoic acid, 1-acenaphthenol, 1—acenaphthenone, acenaphthenequinone, salicylic acid, and catechol; where, the maximum accumulated amount of 1-naphthoic acid measured was 302.1 mg1-1 during the mid-log stage of growth. The degradation of acenaphthene was observed to follow a first order kinetic model with a rate constant 0.528 d-1 and half-life of 1.31 days.
