In the present study, a wild type and mutant strain of Pseudomonas koreensis strain AK-1 (MTCC number 12058) was used for enhanced inorganic phosphorus solubilization under drought stress. Five mutants namely AK-1a, AK-1b, AK-1c, AK-1d and AK-1e were found to solubilize inorganic phosphates more than that of wild type strain in drought stress of 0–10 % polyethylene glycol. On the basis of solubilization index on Pikovskaya agar medium the highest phosphate solubilization index was recorded by mutant strain AK-1c as compared to the wild type strain (AK-1). AK-1c gave the highest Phosphate solubilization index (7.67) at 0 % of polyethylene glycol concentration and lowest (3.6) at the 10 % of polyethylene glycol. AK-1e showed the lowest (4.85) at 0 % and 2.6 at 10 % P solubilization index among the five mutant strains while AK-1 wild type strain showed 4.12 at 0 % and 2.33 at 10 % polyethylene glycol. A highest (19.82) μg/ml at 2 % and 9.73 μg/ml at 10 % PEG inorganic phosphate was solubilized by AK-1c mutant strain which was more than that of wild type variety (17 μg/ml at 2 % and 7.5 μg/ml at 10 % PEG). In plant growth promoting experiment, mutant (AK-1c and AK-1a) bacterial treated soybean plants showed increased shoot length, root length, shoot fresh weight, root fresh weight and number of lateral roots under drought stress as compared to untreated control plants. Bacteria treated soybean plants in Murashige Scoog media showed significant increase in number of lateral roots as compared to the control. © 2014, The National Academy of Sciences, India.

This study explores e-commerce (EC) research trends and forecasts applying bibliometric analysis from 1996 to July 2015 with topic as “e-commerce” in SSCI database. The bibliometric analytical technique is used to examine the topic in SSCI journals from 1996 to July 2015, we found 5429 articles with EC. This paper surveys and classifies EC articles using the eight categories for different distribution status in order to explore how EC research trends and applications have developed in this period. Besides, the paper will perform K–S test to verify the reliability of Lotka’s Law. The study provides an EC roadmap to guide future research and abstract the trend information so that EC researchers can save some time to browse sources since core knowledge will be concentrated in EC core categories. In higher quality publications, it is very common for “success breeds success” phenomenon. © 2015 Akadémiai Kiadó, Budapest, Hungary

Enterprise Application Integration (EAI) is a field of Software Engineering. Its focus is on helping software engineers integrate existing applications at a sensible costs, so that they can easily implement and evolve business processes. EAI solutions are distributed in nature, which makes them inherently prone to failures. In this paper, we report on a proposal to address error detection in EAI solutions. The main contribution is that it can deal with both choreographies and orchestrations and that it is independent from the execution model used. © 2011 Springer-Verlag.

The complete genome sequences of a begomovirus and associated betasatellite was obtained by the rolling circle amplification from rose (Rosa indica) exhibiting dwarfing, leaf distortion and leaf curling symptoms from Rajasthan, India. The sequence of the begomovirus was determined to be 2,741 bp and showed the typical genome arrangement of an monopartite Old World begomovirus. The sequence showed the highest nucleotide sequence identity (98 %) to an isolate of Rose leaf curl virus (RoLCuV), confirming it as an isolate of RoLCuV. The sequence of the rose begomovirus associated betasatellite (1,349 bp) displayed greater than 97 % nucleotide sequence identity to Digera leaf curl betasatellite. Our analysis also demonstrated that recombination events shaped the evolutionary history of RoLCuV. To our knowledge, this is the first report of RoLCuV associated with betasatellite infecting rose in India. © 2014, Australasian Plant Pathology Society Inc.

This study explored several features related to salt tolerance in soybean plants through plant growth-promoting rhizobacteria (PGPR; Pseudomonas sp. strain AK-1, and Bacillus sp. strain SJ-5). We report the significant effect of 1-aminocyclopropane-1-carboxylate deaminase, indole-3-acetic acid production and exopolysaccharide production from both bacterial strains on physical parameters and biochemical activities in Glycine max plants under salt stress. In this report, we investigated the leaf water content, osmolyte accumulation, and activities of stress-responsive enzymes in the absence and presence of salt stress. Control (plants devoid of bacterial strains) and PGPR-inoculated soybean plants were grown in half Murashige and Skoog medium subjected to saline and non-saline conditions. Results showed that PGPR-inoculated plants had superior tolerance against salt stress, as shown by their enhanced plant biomass (fresh weight), higher water content, higher photosynthesis activity, and lower osmotic stress injury. The increased proline accumulation and lipoxygenase activity in PGPR-inoculated plant roots contributed to increased plant tolerance to salt stress. SJ-5-inoculated plants (0.414 U/mg protein) and AK-1-inoculated plants (0.403 U/mg protein) showed higher LOX activity than control plants (0.366 U/mg protein). Proline content was higher in SJ-5-(120 µg/g f.w.) and AK-1-(135 µg/g f.w.)inoculated plants than control plants (90 µg/g f.w.). Peroxidase activity was also higher in PGPR-inoculated plant roots during salinity. These results suggest that, in PGPR-inoculated roots, lipoxygenase plays a role in mitigating the adverse effect of salt stress. Furthermore, enhanced proline maintains osmotic balance and a positive water potential for water entrance into the roots, and peroxidase enzyme reduces oxidative damage by lowering reactive oxygen species level under salt stress. Our results indicated that both Pseudomonas and Bacillus are multifunctional PGPR strains that can promote plant growth, development and reduce salinity stress. However, our Bacillus bacterium strain had more ACC deaminase, phosphate solubilization, and siderophore activity under salt stress as compared to the Pseudomonas strain. © 2015, Springer Science+Business Media New York.

This study presents the first whole genome sequence of Onion yellow dwarf virus (OYDV isolate RR1) from onion (Allium cepa) in India along with phylogenetic and recombination studies. We examined the sequence variability, distribution of simple sequence repeats (SSRs), and recombination breakpoints of different OYDV geographical isolates. The P1 and P3 regions of OYDV show a higher rate of sequence variability in amino acid and nucleotide sequences than other genomic regions. Entropy peaks of deduced amino acid sequences were higher in both regions (P1 and P3) of different OYDVs. The observed frequency of microsatellites was also higher in the P3 region of all OYDV genomes. The Indian isolate RR1 showed 75–98 % similarity with the other OYDV isolates in nucleotide and amino acid sequences and has 43 microsatellites and two compound microsatellites. It was most closely related to garlic isolate MS/SW1 from Australia. Isolate RR1 contained six recombination breakpoints in different genomic regions with the major parent related to the MS/SW1 (Australian) and SG1 (Spanish) OYDV isolates. The phylogenetic and recombination study demonstrated the divergence of Indian isolate RR1 from OYDV isolate from Australia. © 2015 Koninklijke Nederlandse Planteziektenkundige Vereniging

The aim of the present study was to analyze induced expression of defense-related proteins in the soybean plants by rhizobacterial stain Carnobacterium sp. SJ-5 upon challenge inoculation with Fusarium oxysporum. Determination of the enzymatic activity of the different defense-related enzymes, phenylalanine ammonia lyase (PAL), lipoxygenase (LOX), peroxidase (POD) and polyphenol oxidase (PPO) was performed in the major parts of Glycine max L. Merrill using spectrophotometric method. Native-polyacrylamide gel electrophoresis analysis of the POD and PPO was employed followed by activity staining to find out the isoforms of respective enzymes. Activities of the PAL, LOX, POD and PPO were found to be highest in the bacterized root tissue of the soybean plants challenged with F. oxysporum. Isoform analysis revealed that PPO1, PPO4 and POD2 isoforms were expressed at higher levels in bacterized soybean root tissues challenge inoculated with the pathogen. Conclusively it was found that bacterial strain Carnobacterium sp. SJ-5 protect soybean plants from wilt disease caused by F. oxysporum by elicitation of the defense-related enzymes.

Petunia hybrida is an important ornamental plant grown in many countries including India. It is a good model plant for the study of genetics and molecular biology. During a survey in 2013-2014, severe leaf curling was observed on most of the P. hybrida grown in the Sikar district, Rajasthan. The infected plants were analyzed for begomovirus infection by rolling circular amplification (RCA) and sequenced. Full length sequences confirmed the association of monopartite begomovirus with betasatellites. Phylogenetic analysis showed the highest percentage of identity with Chilli leaf curl virus (ChLCuV) and therefore considered to be an isolate of ChLCuV. Recombination analysis showed that ChLCuV has broadened its host range by recombination process. To the best our knowledge, this is the first report of natural occurrence of ChLCuV on P. hybrida in India.
