ISODATA classification using Fuzzy Logic

In current days remote sensing is mainly recent application in many sectors. Remote Sensing (RS) refers to the science of identification of earth surface facet and analysis of their geo-biophysical property via electromagnetic emission as a model for interaction. Spectral, spatial, temporal and polarization signatures are key features of the sensor/target, which make easy target bias. Earth surface data seen by the sensors in altered wavelengths (reflected, scattered and/or emitted) is radio metrically and geometrically right by extraction of spectral data. RS data is a synoptic read, pedestrian exposure with calibrate sensors to work out changes, observations at various resolutions, deals with a alternative for normal resources management as compare to standard methods. This remote sensing utilizes dissimilar images like multispectral, hyper spectral or ultra-spectral. The remote sensing image classification is being of the significant methods to sort image. In order to state we classify the ISODATA classification amid fuzzy logic. In this we experimenting fuzzy logic be affectionate of spatial, spectral texture methods in that dissimilar sub methods to be worn for image classification

Bioremediation Of Dairy Wastewater Using Microalgae For The Production Of Biodiesel

This study describes the feasibility for treatment of dairy waste waters in batch cultures by using selected strains of green microalgae namely Chlorella vulgaris, Botryococcus braunii and a mixed algal culture in indoor and outdoor. The Biomass productivity peaked on the 6th day. Best results were observed in C. vulgaris strain in both indoor and outdoor studies with biomass productivity of 0.51g/L, chlorophyll concentration of 0.039mg/L and lipid yield of 0.030g/L in indoor cultures whereas 0.59g/L of biomass productivity, 0.045mg/L chlorophyll concentration and 0.035g/L lipid yields were obtained in outdoor studies.. Gas Chromatography mass Spectrophotometer (GC MS) analysis of the extracted lipids showed that major components in C.vulgaris and mixed algae were palmitic acid, staeric acid and oleic acid where as oleic acid was the major component in B.braunii and palmitic acid, staeric acid were also present in minor amounts

Insilico analysis of Arabidopsis ferric reductase oxidases (FRO) proteins associated with iron homeostasis

The ferric reduction oxidase (FRO) gene family is involved in various biological processes of plants and plays an essential role in metal homeostasis, tolerance, and signaling networks in response to several abiotic stresses. Our study describes the structural, functional characterization, and evolutionary relationships of eight Arabidopsis FRO proteins. The studies predicted the subcellular localization of FRO proteins to the plasma membrane, mitochondria, and chloroplast organelles. The structural analysis revealed localization of proteins onto the first and fifth chromosomes having 8-9exons and 8-10 transmembrane helices. The protein features of FRO proteins revealed 699-747 amino acids having 79600.02-84126.3 (Da) molecular weight. The six highly conserved protein motifs were predicted with 45-50 amino acids long representing ferric chelate reductase family domains. The phylogeny tree constructed using Clustal W divided the FRO proteins into two clusters and the interactome network revealed the co-expression of COPT1, NRAMP1, NRAMP3, NRAMP4, FRD3, OPT3, IRT1, IRT2, ZIF1, PYE proteins along with the seven FRO proteins

Glucose transport by epithelia prepared from harvested enterocytes

Transformed and cultured cell lines have significant shortcomings for investigating the characteristics and responses of native villus enterocytes in situ. Interpretations of results from intact tissues are complicated by the presence of underlying tissues and the crypt compartment. We describe a simple, novel, and reproducible method for preparing functional epithelia using differentiated enterocytes harvested from the small intestine upper villus of adult mice and preterm pigs with and without necrotizing enterocolitis. Concentrative, rheogenic glucose uptake was used as an indicator of epithelial function and was demonstrated by cellular accumulation of tracer 14C d-glucose and Ussing chamber based short-circuit currents. Assessment of the epithelia by light and immunofluorescent microscopy revealed the harvested enterocytes remain differentiated and establish cell–cell connections to form polarized epithelia with distinct apical and basolateral domains. As with intact tissues, the epithelia exhibit glucose induced short-circuit currents that are increased by exposure to adenosine and adenosine 5′-monophosphate (AMP) and decreased by phloridzin to inhibit the apical glucose transporter SGLT-1. Similarly, accumulation of 14C d-glucose by the epithelia was inhibited by phloridzin, but not phloretin, and was stimulated by pre-exposure to AMP and adenosine, apparently by a microtubule-based mechanism that is disrupted by nocodazole, with the magnitudes of responses to adenosine, forskolin, and health status exceeding those we have measured using intact tissues. Our findings indicate that epithelia prepared from harvested enterocytes provide an alternative approach for comparative studies of the characteristics of nutrient transport by the upper villus epithelium and the responses to different conditions and stimuli

Salt-tolerant genes from halophytes are potential key players of salt tolerance in glycophytes

Crop productivity strongly depends on several biotic and abiotic factors. Salinity is one of the most important abiotic factors, besides drought, extreme temperatures, light and metal stress. The enhanced burden of secondary salinization induced through anthropogenic activities increases pressure on glycophytic crop plants. The recent isolation and characterization of salt tolerance genes encoding signaling components from halophytes, which naturally grow in high salinity, has provided tools for the development of transgenic crop plants with improved salt tolerance and economically beneficial traits. In addition understanding of the differences between glycophytes and halophytes with respect to levels of salinity tolerance is also one of the prerequisite to achieve this goal. Based on the recent developments in mechanisms of salt tolerance in halophytes, we will explore the potential of introducing salt tolerance by choosing the available genes from both dicotyledonous and monocotyledonous halophytes, including the salt overly sensitive system (SOS)-related cation/proton antiporters of plasma (NHX/SOS1) and vacuolar membranes (NHX), energy-related pumps, such as plasma membrane and vacuolar H+ adenosine triphosphatase (PM& V-H+ATPase), vacuolar H+ pyrophosphatases (V-H+PPase) and potassium transporter genes. Various halophyte genes responsible for other processes, such as crosstalk signaling, osmotic solutes production and reactive oxygen species (ROS) suppression, which also enhance salt tolerance will be described. In addition, the transgenic overexpression of halophytic genes in crops (rice, peanut, finger millet, soybean, tomato, alfalfa, jatropha, etc.) will be discussed as a successful mechanism for the induction of salt tolerance. Moreover, the advances in genetic engineering technology for the production of genetically modified crops to achieve the improved salinity tolerance under field conditions will also be discussed

Integrated transcriptome, small RNA and degradome sequencing approaches provide insights into Ascochyta blight resistance in chickpea

Ascochyta blight (AB) is one of the major biotic stresses known to limit the chickpea production worldwide. To dissect the complex mechanisms of AB resistance in chickpea, three approaches, namely, transcriptome, small RNA and degradome sequencing were used. The transcriptome sequencing of 20 samples including two resistant genotypes, two susceptible genotypes and one introgression line under control and stress conditions at two time points (3rd and 7th day post inoculation) identified a total of 6767 differentially expressed genes (DEGs). These DEGs were mainly related to pathogenesis�related proteins, disease resistance genes like NBS�LRR, cell wall biosynthesis and various secondary metabolite synthesis genes. The small RNA sequencing of the samples resulted in the identification of 651 miRNAs which included 478 known and 173 novel miRNAs. A total of 297 miRNAs were differentially expressed between different genotypes, conditions and time points. Using degradome sequencing and in silico approaches, 2131 targets were predicted for 629 miRNAs. The combined analysis of both small RNA and transcriptome datasets identified 12 miRNA�mRNA interaction pairs that exhibited contrasting expression in resistant and susceptible genotypes and also, a subset of genes that might be post�transcriptionally silenced during AB infection. The comprehensive integrated analysis in the study provides better insights into the transcriptome dynamics and regulatory network components associated with AB stress in chickpea and, also offers candidate genes for chickpea improvement

Transcriptome analysis reveals key genes associated with root‑lesion nematode Pratylenchus thornei resistance in chickpea

The root-lesion nematode, Pratylenchus thornei, is one of the major plant-parasitic nematode species causing significant yield losses in chickpea (Cicer arietinum). In order to identify the underlying mechanisms of resistance to P. thornei, the transcriptomes of control and inoculated roots of three chickpea genotypes viz. D05253 > F3TMWR2AB001 (resistant advanced breeding line), PBA HatTrick (moderately resistant cultivar), and Kyabra (susceptible cultivar) were studied at 20 and 50 days post inoculation using the RNA-seq approach. On analyzing the 633.3 million reads generated, 962 differentially expressed genes (DEGs) were identified. Comparative analysis revealed that the majority of DEGs upregulated in the resistant genotype were downregulated in the moderately resistant and susceptible genotypes. Transcription factor families WRKY and bZIP were uniquely expressed in the resistant genotype. The genes Cysteine-rich receptor-like protein kinase 10, Protein lifeguard-like, Protein detoxification, Bidirectional sugar transporter Sugars Will Eventually be Exported Transporters1 (SWEET1), and Subtilisin-like protease were found to play cross-functional roles in the resistant chickpea genotype against P. thornei. The identified candidate genes for resistance to P. thornei in chickpea can be explored further to develop markers and accelerate the introgression of P. thornei resistance into elite chickpea cultivars

INTERNATIONAL JOURNAL OF PHARMACY & LIFE SCIENCES Screening of potential efficacy of dietary ginger on ethanol induced oxidative stress in rat cardiac tissue: A study on changes in basic metabolic profiles

Abstract The present study was premeditated to examine the possible mechanisms where by ginger (Zingiber officinale) could protect cardiac tissue from alcohol toxicity in rats. The carbohydrate metabolic profiles like total carbohydrates, pyruvate, total proteins, free amino acids and lactate levels were measured in heart tissue. The total carbohydrates, pyruvate, and total proteins were significant declined while free amino acids, lactate levels were significant increased in alcohol intoxicated rats. Whereas with ginger (200 mg/kg body weight) treatment shown significant increase in the total carbohydrates, total proteins and pyruvate levels, whereas free amino acids, lactate levels were significant drop in the cardiac tissues. From the present study, we conclude that ginger protects the heart tissue from alcohol toxicity in rats, this may be due to the presence of many bioactive compounds in ginger

Genome-Wide Identification, Characterization, and Expression Analysis of Small RNA Biogenesis Purveyors Reveal Their Role in Regulation of Biotic Stress Responses in Three Legume Crops

Biotic stress in legume crops is one of the major threats to crop yield and productivity. Being sessile organisms, plants have evolved a myriad of mechanisms to combat different stresses imposed on them. One such mechanism, deciphered in the last decade, is small RNA (sRNA) mediated defense in plants. Small RNAs (sRNAs) have emerged as one of the major players in gene expression regulation in plants during developmental stages and under stress conditions. They are known to act both at transcriptional and post-transcriptional levels. Dicer-like (DCL), Argonaute (AGO), and RNA dependent RNA polymerase (RDR) constitute the major components of sRNA biogenesis machinery and are known to play a significant role in combating biotic and abiotic stresses. This study is, therefore, focused on identification and characterization of sRNA biogenesis proteins in three important legume crops, namely chickpea, pigeonpea, and groundnut. Phylogenetic analysis of these proteins between legume species classified them into distinct clades and suggests the evolutionary conservation of these genes across the members of Papillionidoids subfamily. Variable expression of sRNA biogenesis genes in response to the biotic stresses among the three legumes indicate the possible existence of specialized regulatory mechanisms in different legumes. This is the first ever study to understand the role of sRNA biogenesis genes in response to pathogen attacks in the studied legumes
