Subject: Adsorption of arsenic using low cost adsorbents: guava leaf biomass, mango bark and bagasse
Keywords: Adsorption, arsenite ion-As (III), isotherms, kinetics, low-cost adsorbents
Abstract: Adsorbents prepared from inexpensive materials of guava leaf biomass, mango bark and bagasse were studied for As (III) removal from the aqueous solution. The effects of pH, contact time, initial As (III) concentration and adsorbent dosage on the adsorption of As (III) were studied using batch experiments. Adsorption process was also verified with Langmuir, Frendlich, Temkin and Redlich-Peterson models. Langmuir isotherm fitted best in the experimental data. Application of Langmuir isotherm to the system yielded the maximum capacities of 1.35 mg g-1, 1.25 mg g-1 and 1.05 mg g-1 for bagasse, mango bark and guava leaf biomass respectively, in the range of As (III) concentration as 10-140 mg 1-1.The dimensionless equilibrium parameter, RL, signifies favourable adsorption of As (III) on all adsorbents and was observed to be in the range of 0.029-0.294, 0.21-0.235 and 0.021-0.234, for bagasse, mango bark and guava leaf biomass respectively (0<RL<1).The adsorption process was observed to follow pseudosecond-order kinetic model.

Subject: Tissue-specific activation tagging in Arabidopsis thaliana for identification and isolation of genes of agronomic importance
Keywords: Activation tagging, Arabidopsis thaliana, morphological variants, promoters
Abstract: Activation tagging is used to recover and clone dominant gain-of function alleles and usually employs a T-DNA vector containing four tandem copies of the CaMV35S enhancer sequence outward usually at the right border. This strategy, however, is not efficient as it could result in overexpression of multiple genes or genes far away from the insertion site. Therefore, we tested constitutive (CaMV35S) and tissue-specific (TFL1 and rbcS2B) promoters for activation tagging. From an initial screening of 400 T1 plants, we identified several morphological variants which include seedling mutants(single cotyledon, slow seedling growth, long root, short root), leaf mutants (fused leaves, excess rosettes, altered shape, hyponastic leaves, bushy rosettes, altered leaf polarity), inflorescence mutants (fascinated inflorescence , inflorescence fused with the petiole of rosette leaf) and flowering time and growth habit mutants (dwarf, tall , miniature, late flowering, sturdy stem.) Comparison of different activation tagging populations for different categories of mutants in the TFL1 promoter activation tagged population; leaf and inflorescence mutant frequencies were higher in rbcS2B promoter activation tagged population, while the flowering time and growth habit mutant frequency was higher in CaMV35S promoter activation tagged population. Flanking sequence analysis of three of the mutants showed that all the mutants carried an insertion in the intergenic region. Segregation analysis of seedlings for kanmycin resistance showed that on average each mutant carried about 1.3 copies of T-DNA.

Subject: Isolation and characterization of NBS-encoding disease resistance gene analogs in watermelon against fusarim wilt.
Keywords: Disease management, fusarium wilt, resistance genes, watermelon
Abstract: Fusarium wilt (Fusarium oxysporum f.sp.niveum) in water melon is one of the deadliest diseases around the globe, and availability of disease –resistant varieties is moderate. Diseases management utilizing resistance genes(R-genes) /resistance gene analogs (RGAs) has proven to be a promising and successful approach. In the present study, six watermelon Gas were isolated from wild, fusarium wilt resistant genotype IIHR-82 (Citrullus lanatus var.citroides ) using degenerate primers that identify nucleotide binding site-leucine –rich repeat (NBS-LRR) regions. Multiple sequence alignment of these RGAs identified the characteristic NBS-LRR motif, and BLASTp search revealed similarity of these RGAs with other pathogenesis-related proteins. Phylogeny and motif analysis revealed genetic diversity of RGAs within those isolated from watermelon and other plant R-genes. The watermelon RGAs isolated in this study contained both TIR-NBS-LRR (TNL) and non-TIR –NBS-LRR (CNL) classes of R-genes. Protein secondary structure prediction of these watermelon RGAs revealed the composition of proteins, including α-helix, ẞ-strand, disordered region and other template-related information. Watermelon RGAs identified in the present study will help in the development of RGA-based markers for resistance to fusarium wilt of watermelon.

Subject: Trends and insights of agroforestry practices in Madhya Pradesh, India
Keywords: Agroforestry practices, agriculture, agro-climatic regions, horticulture
Abstract: Agroforestry practices in Madhya Pradesh (MP), India existed in the primordial times, which can be evidenced almost in every region of the state; however, the pace of scientific inclusion in agroforestry and its extension is slow. There is lack of priority and limited work has been done related to agroforestry practices, possibly due to the presence of large natural forest area in the state. In the present context, to meet the national target of forest cover and to reduce pressure on nature forest, agroforestry seems to be a viable option as it provides a source of income for farming and tribal communities along with countless environmental benefits. This article provides a review and insight of agroforestry and extent of agriculture, horticulture and agroforestry in MP. It also provides information on diverse tree species under agroforestry systems, a mosaic of tree-crop combinations and horticulture species preferred by the farmers in different agro-climatic zones of the state. The authors have also tried to enlist the efforts of various government initiatives and other agencies involved in the extension of agroforestry in the state. The roles of MP Forest Department, MP Forest Development Corporation and allied Departments of the State in agroforestry and tree planting have also been discussed. Marketing of agroforestry produce, farmers’ involvement in agroforestry practices and identification of key policy constraints of agroforestry in the state have been discussed and critically analysed.

Subject: Potassium in shrink-Swell soils of India
Keywords: Clay mineralogy, fertilizers, mineralogy, potassium availability, swellshrink soils.
Abstract: This article reviews the information regarding potassium (K) status of Indian soils based on research conducted since 1929.The patterns and lacunae regarding potassium consumption in India are also mentioned. The role of minerals in potassium availability vis-a-vis forms of potassium is discussed and elucidated with suitable clay mineralogical evidences. The article also highlights the problems of potassium availability to plants in Indian shrink-swell soils. We have pointed out the inefficiency of the universal method used for assessing plant-available K (1N NH4OAc) in Indian shrink-swell soils, as observed from extensive K response studies. The current practices of assessing only plant-available K is not adequate to detect native changes in soil potassium. This paradoxical situation necessitates revision and revalidation of the existing potassium fertilizer recommendations, which are being adopted since four decades. A holistic research envisaging soil test crop response and mineralogical studies will help in revising potassium evaluation methods in India, leading to judicious fertilizer application by the farmers.

Abstract: Management of water resources in Indi has been a challenge whose magnitude has risen manifolds over the past 50 years due to a variety for reasons, notably the rising demands and growing environmental degradation. Broadly, most of the challenges in water management in India can be categorized in the following groups: (a) water availability, variability and increasing withdrawals, (b) environment and quality, (c) project constructions, (d) water sharing disputes, (e) water governance and institutions, and (f) challenges induced due to climate and land-use cover changes. Here we discuss each of these challenges in detail. It is suggested that conservation of water and management of variability should be a cornerstone of water resources management in India. This note also suggests remedies to address the challenges and covers new initiatives by the Government of India (GoI).

Abstract: The middle Indo-Gangetic Plain (MIGP) of India covering eastern Uttar Pradesh and Bihar is endowed with rich and diverse natural resources (land, water and environment), but low productivity and income. Rice-based cropping systems have maximum coverage of net sown area (9.64 m ha) in the MIGP. Wheat, mustard, potato, maize and pulses are the major crops grown in rotation with rice. Rice-Wheat system is extensively practised by the farmers of the region. This system requires high inputs in terms of machinery, nutrients, water and agro-chemicals. Unlike the northwestern part of the IGP Trans and Upper IGP), the rice-wheat system of the MIGPs are less mechanized/labour-intensive due to small and fragmented landholdings and resource-poor farmers.

Abstract: The rugged landscape of the Indian Himalayan region elevates the risk of hazard events and holds back socio-economic development opportunities for remote and vulnerable communities. Particularly notable are landslides, floods, forest fires and earthquakes. Recent international assessment of disaster impacts (1996-2015) revealed that India as a whole suffered the fifth largest mortality, especially related to flood events. The 23-24 September 2018 floods which impacted the Beas River water shed in Kullu district,Himachal Pradesh highlight the significant damages (to infra structure and environment), disruption and costs that disaster events inflict upon us.

Abstract: On 19 June 2019, ‘Day Zero’ was declared in Chennai, Tamil nadu, India. The four main water reservoirs had cracked open with dryness-there was no water left in the city. The news shocked and surprised many because as late as 2015, Chennai was flooded and more than 300 lives were lost. These flood and drought disasters in the city did not occur suddenly, rather they happened gradually through depleting groundwater , drying rivers and vanishing wetlands, much like a predator closing in openly visible, yet invisible by its apparent quiescence. It may appear that we are weak at anticipating dangers, but this is not true. We can easily sense imminent dangers, but this is not true. We can easily sense imminenet dangers that generate visual stimulation. Unfortunately, the signals relayed from the existing water resources monitoring network in the country are shrouded with uncertainty due to spatially and temporally sparse observations. Therefore, while we hear about environmental and water issues, and vaguely sense something is going wrong, yet strong steps are not taken because our minds do not visualize them as imminent dangers.

Abstract: The study presents assessment and potential oceanographic applications of sea-surface temperature (SST), ocean net shortwave radiation (SWR) and chlorophyll concentration (CC) observations obtained from various geostationary platforms.SST and SWR from imager on board Indian National Satellite (INSAT 3D) and CC from Global Ocean Color Imager (GOCI) on –board communication ocean and meteorological satellite (COMS) have been used in the analysis .Relative advantages of high temporal resolution obtained from the geostationary platform compared to polar orbiting platforms are demonstrated. Comparison of INAT-3D SST with observations gives a correlation of 0.85 and RMSE of 0.81 K. These platforms definitely provide a highly reliable source of continuous observations, which is useful in monitoring dynamic oceanic features such as thermal fronts, chlorophyll blooms, air-sea exchange fluxes, etc. on diurnal to daily timescales.

Abstract: Moho depth or simply, Moho, in general , describes the boundary between the earth’s crust and the mantle and is a very important geophysical parameter. It is also related to the earth’s crustal thickness at any point. Geoid and gravity anomalies derived from satellite altimetry are gradually gaining importance in marine geo-scientific investigations. However, satellite gravity technique is not working over land/continent. So, we need to develop technique like the VMM model which is equally working over land. In addition of generating crustal thickness, it also saves energy to generate Bouguer anomaly over land and ocean.

Subject: Soybean methylation analysis during strontium stress using methylation-sensitive amplified polymorphism
Keywords: Methylation/demethylation, polymorphism, soybean, strontium stress
Abstract: The effect of strontium stress on the pattern and degree of DNA methylation in soybean seedlings was analysed using the methylation-sensitive amplified polymorphism (MSAP) method. The growth traits were inhibited bySrCl2 treatments. A total of 167 loci were determined and evaluated for DNA methylation after different treatments. The level of cytosine methylation initially decreased and then increased with increasing Sr concentration. Methylation was lowest after 10 mmol/l SrCl2 treatment. Strontium stress resulted in a 57.48 % alteration of DNA methylation pattern in 5’ –CCGG-3’ loci. The pattern variation initially decreased and then increased along with increasing strontium concentration. There was a positive correlation between the total methylation and full methylation induced by strontium stress, and weight and length of shoots and roots in soybean. Overall, the changes in the pattern and degree of methylation may be a key regulatory mechanism for soybean adaptation to strontium.
