The ability of herbicides to be adsorbed by the soil and sediment and their tendency to be desorbed are some of the most important factors affecting soil and water contamination. Therefore, a sorption study was conducted to evaluate the adsorption of cyhalofop-butyl, butyl (2R)-2-[4-(4-cyano-2-fluorophenoxy) phenoxy] propanoate, in the sandy clay loam and clayey soils using a batch equilibrium method. The adsorption of cyhalofop-butyl was found positively related with the clay and organic carbon content. Freundlich constants (Kf) of cyhalofop-butyl in the clayey and sandy clay loam were found to be 13.39 and 2.21, respectively. Sorption coefficients (Koc) and distribution coefficients (Kd) were found to be 265.38 and 2,092.79, and 1.38 and 11.48, for sandy clay loam and clayey soils, respectively. The adsorption isotherm suggested a relatively higher affinity of cyhalofop-butyl to the adsorption sites at low equilibrium concentrations. The low value of the soil organic carbon partition coefficient (Koc) of cyhalofop-butyl in the sandy loam soil suggested its weaker adsorption in soil and thus increased its risk of mobility into water sources; hence, it should be used judiciously to prevent groundwater contamination © 2014 Springer International Publishing Switzerland.

This study was conducted to evaluate cyhalofop-p-butyl mobility in a sandy loam soil and subsequent distribution of residues at various depths under field conditions. Soil samples were taken from 0 to 150 cm depths at 3-90 d after rains in lysemeter of 1 and 2 m depths. Cyhalofop-p-butyl application at two rates and subsequent precipitation had a significant impact on soil, physico-chemical properties and herbicide mobility. Precipitation caused substantial mobility of cyhalofop-p-butyl in the soil and 1.1-7.6 μg L-1 of cyhalofop-p-butyl was found in leachates. Cyhalofop-p-butyl residues in the leachates were probably due to preferential flow through the soil. Cyhalofop-p-butyl residues were detected in significant amounts from the soil up to 10 d, later, residues were found below the detection limit but its three transformation products viz., cyhalofop acid, diacid, and phenol were detected. © 2014 Copyright © Taylor & Francis Group, LLC.

Effect of packaging techniques and storage environment was assessed for maintaining quality and shelf life of guava. Changes in headspace gases, physiological loss in weight (PLW), ascorbic acid, texture, colour and subjective quality were evaluated. The in-pack guava created a suitable headspace with low O2 and high CO2 concentrations, which resulted in a better retention of freshness of the guava. Shrink packaging with bi-axially oriented polypropylene (BOPP) could not yield better result under ambient storage because of high water vapour transmission rate (WVTR) of the film and consequently loss of turgidity of fruits. Modified atmospheric packaging (MAP) in polypropylene (PP) with pin holes was found to be the best followed by vacuum pack with PP in cold condition and could be used to store for 28 and 24 days with maintenance of texture, colour, ascorbic acid and marketability. It is also inferred that under ambient conditions guava could be stored for 4 days using low density polyethylene (LDPE) with pin holes and PP with pin holes as MAP storage. The research findings of the study would give an innovative facet for fresh guava preservation and enhancing the commercial potential along with open new avenues for fresh fruit and vegetable industry. © 2014 Elsevier B.V.

The effect of packaging materials [low density polyethylene (LDPE), polypropylene (PP)] and storage environment [modified atmospheric packaging (MAP)] on shelf life enhancement of bell pepper in terms of quality attributes such as physiological weight loss, ascorbic acid, texture, surface colour and subjective quality analysis have been studied at ambient and refrigerated condition. Different packaging techniques used for the experiment were MAP with LDPE, MAP with PP, MAP in perforated LDPE films, MAP in perforated PP films, shrink packaging with bi-axially oriented PP (BOPP) film and vacuum packaging with PP film. The in-pack bell pepper created a suitable headspace environment with low O2 and high CO2 concentrations, which resulted in a better retention of freshness of the vegetables and its marketability. Shrink packaging with BOPP film could not yield better result under ambient storage because of high water vapor transmission rate of the film and consequently loss of turgidity of the vegetables. Among different packaging techniques and storage conditions, MAP with PP film in refrigerated condition was found to be the best followed by vacuum pack with PP film in refrigerated condition and could be used to store for 20 days for bell pepper with maintenance of texture, colour, ascorbic acid and marketability. It is also inferred that under ambient conditions, bell pepper could be stored for 4 days using ventilated LDPE and PP as MAP storage. Further studies are needed to evaluate the sensory aspects, as well as to microbiological evaluation to characterize the fresh bell pepper during storage. © 2014 Springer Science+Business Media New York.

The present investigation was undertaken to study the role of working conditions in occupational hazards among bidi rollers occupationally exposed to tobacco dust with reference to DNA damage in peripheral blood lymphocytes. Initially, biomonitoring was conducted by estimating urinary thioether to detect the extent of xenobiotic exposure, and genotoxicity was evaluated by assessing DNA damage and micronucleus frequency in buccal epithelial cells in female bidi rollers occupationally exposed to bidi tobacco dust. Student′s t-test was used to test the significance between the means. Results showed a significant increase in urinary thioether level in during-shift urine samples as compared to pre-shift samples, which indicated exposure of bidi rollers to xenobiotic compounds. A significant increase in DNA damage was observed in the rollers working in confined environment as compared to those who worked in open and mixed kind of working conditions. Keeping in view the adverse effects of tobacco inhalation on the genotoxic effects in bidi rollers as an occupational hazard and in order to minimize the hazardous effects, it is recommended that masks should be worn by the bidi rollers during work to minimize inhalation of tobacco dust. Gloves should be worn particularly if there are bruises etc. in the palm. To minimize the absorption through eyes, covered glasses should be worn. The entire process of bidi rolling may be done preferably under well ventilated conditions. Due care to be taken to sit in the direction facing the direction of wind to avoid inhalation of blown away tobacco dust.

Pepper leaf curl virus (PepLCV) is a serious threat to pepper (Capsicum spp.) production worldwide. Molecular mechanism underlying pepper plants response to PepLCV infection is key to develop PepLCV resistant varieties. In this study, we generated transcriptome profiles of PepLCV resistant genotype (BS-35) and susceptible genotype (IVPBC-535) after artificial viral inoculation using microarray technology and detail experimental procedures and analyses are described. A total of 319 genes differentially expressed between resistant and susceptible genotypes were identified, out of that 234 unique genes were found to be up-regulated >2-fold in resistant line BS-35 when compared to susceptible, IVPBC-535. The data set we generated has been analyzed to identify genes that are involved in the regulation of resistance against PepLCV. The raw data have been deposited in the Gene Expression Omnibus (GEO) database under accession number GSE41131.

Ethylene is an essential plant hormone also known as a stress hormone because its synthesis is accelerated by induction of a variety of biotic and abiotic stress. The plant growth promoting bacteria containing the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase enhances plant growth by decreasing plant ethylene levels under stress conditions. The expression of ACC deaminase (acdS) gene in transgenic plants is an alternative approach to overcome the ethylene-induced stress. Several transgenic plants have been engineered to express both bacterial/plant acdS genes which then lowers the stress-induced ethylene levels, thus efficiently combating the deleterious effects of environmental stresses. This review summarizes the current knowledge of various transgenic plants overexpressing microbial and plant acdS genes and their potential under diverse biotic and abiotic stresses. Transcription regulation mechanism of acdS gene from different bacteria, with special emphasis to nitrogen fixing bacteria is also discussed in this review. © 2014 Springer Science+Business Media Dordrecht.

Soybean is an economically important leguminous crop. Genetic improvements of soybeans have focused on enhancement of seed and oil yield, development of varieties suited to different cropping systems, and breeding resistant/tolerant varieties for various biotic and abiotic stresses. Plant breeders have used conventional breeding techniques for the improvement of these traits in soybean. The conventional breeding process can be greatly accelerated through the application of molecular and genomic approaches. Molecular markers have proved to be a new tool in soybean breeding by enhancing selection efficiency in a rapid and time-bound manner. An overview of molecular approaches for the genetic improvement of soybean seed quality parameters, considering recent applications of marker-assisted selection and ‘omics’ research, is provided in this article. © 2016 Springer Science+Business Media Dordrecht

Present investigation was carried out to evaluate genetic diversity among 38M6 population of oat cv. JO-1. To validatethe observed morpho-physiological variations, these lines were analyzed with 21 ISSR primers. A total of 132 loci were amplified by these 21 ISSR markers and 116 loci were found to be polymorphic (87.87%). The genetic similarity coefficient values among 39 oat genotypes based on ISSR analysis ranged from 0.305 to 0.957. The cluster analysis divided the oat genotypes into two groups. Mutants JMO 81 and JMO 82 were found to be most divergent, hence can be used as parents in breeding program for the development of superior cultivars.
