Azospirillum is considered to be a most effective Plant Growth Promoting Rhizobacteria (PGPR), which is responsible for various modifications in plants to cope with stress conditions. Therefore, the present research was planned to evaluate the effect of Azospirillum lipoferum (GQ 255949) inoculation on growth, biochemical, yield attributes of canola grown under drought conditions. Two different modes of inoculation were used; i.e., inoculation of seeds directly and exposure of planted seed in the rhizosphere. Drought stress was imposed at flowering stage. Azospirillum seed inoculation was helped mitigate stress effects by improving germination percentage up to 12.49%. Root area was increased up to 18.5% and 11.38% with seed and rhizosphere inoculation in drought stress respectively. Chlorophyll contents and water potential were increased 12.21%, and 11.0% in seeds inoculated under drought conditions. Superoxide dismutase activity was decrease up to 24.6% and 12.5% in seed and rhizosphere inoculated plants under well watered conditions. Seed inoculation was most effective, as number of seeds per pod and seed weight per plant was significantly increased up to 25%, and 14.28% as compared to the control. In conclusion, Azospirillum can mitigate deleterious effects of drought stress in canola under water deficiency conditions. © 2016 The Author(s).

Newcastle disease virus (NDV) was first reported in 1926. Since then, the NDV has been prevalent in domestic and wild birds representing a diverse and continually evolving group of viruses, consisting one genotype for class I NDV isolates and eighteen genotypes for class II NDV isolates. The emergence of new virulent genotypes from global epizootics and the year-to-year changes observed in the genomic sequence of NDV of low and high virulence implies that distinct genotypes of NDV are simultaneously evolving at different geographic locations across the globe. This vast genomic diversity may be favoured by the large variety of avian species susceptible to NDV infection and by the availability of highly mobile wild bird reservoirs. In certain countries such as Pakistan, the viruses of sub-genotype VIIi have replaced NDV isolates of genotype XIIIa, which were commonly isolated in 2009-2011, and have become the predominant sub-genotype causing ND outbreaks since 2012, suggesting the existence of a fifth panzootic. The genomic diversity of NDV increases the possibility of diagnostic failures, resulting in unidentified infections. Therefore, continuous monitoring of viral evolution and periodic updates of vaccine seed strains are warranted to achieve efficient control and eradication of ND. This review reports on the emergence and evolution of ND viruses and vaccination strategy in Pakistan. Copyright © World's Poultry Science Association2017

The right requirements are considered as a part and parcel of software quality. Since the emergence of software engineering the perfect requirements have a deeper effect on the overall quality of software systems. This research paper is focusing on the shortcomings or limitations of existing software requirements prioritization techniques and paves the way for researchers to explore new horizons in software requirements prioritization. Most of the techniques are solving the plight of small projects or toy applications. There is not a single evidence of a successful prioritization technique that would solve the problem of large set of requirements. The innovative requirements prioritization approaches are required for systems where user requirements increase in hundreds and even in thousands. The existing techniques are not providing sufficient automation for such systems due to their certain limitations. © 2011 IEEE.

Root-knot nematodes (Meloidogyne spp.) are one of the most destructive pathogens of vegetables. The cultivars resistant to root-knot nematodes have comparatively better crop yield than susceptible varieties and can be employed as a component of integrated nematode management. In the present study, 15 cultivars of cucumber (Cucumis sativus) were tested for their response to Meloidogyne incognita by inoculating with 3000 2nd stage juveniles of the nematode. All cultivars varied significantly in causing reductions in growth parameters over their controls. Likewise, all cultivars behaved differently regarding formation of galls and egg masses and reproductive factor. It was found that none of the tested cultivars was found immune or highly resistant. Long Green was the only cultivar which was found resistant against M. incognita as it showed minimum galls (8.2) and reductions in growth parameters. On the other hand, cultivars Mehran, Mirage, Thamin-II, and Royal Sluis were highly susceptible as evident by maximum galls (>100) on their roots and reductions in growth parameters. Similarly, the cultivars Green Wonder, Cucumber Citriolo and Poinsett were moderately susceptible (31-70 galls) while Babylon, Cobra and Falcon-560 (71-100 galls) were susceptible and reductions in growth parameters of these cultivars were less than those in highly susceptible cultivars. Four cultivars, Marketmore, Dynasty, Pioneer-II, and Summer Green, were rated as moderately resistant (11-30 galls) as these cultivars showed less damage by the nematode than moderately susceptible, susceptible and highly susceptible cultivars. © 2012 Elsevier Ltd.

Because of being costly and pernicious to the environment and human health, the use of nematicides has become prohibitive in many countries and the management of plant parasitic nematodes using antagonistic plants can be a very attractive alternative. In the present studies the effectiveness of aqueous extracts of Cannabis sativa and Zanthoxylum alatum was assessed on hatching, mortality and infectivity of Meloidogyne incognita at different concentrations viz. S, S:1, S:5, S:10, S:25, S:50 and S:100. Both the plants had significant effects on juvenile mortality and hatching inhibition in a dose-dependent manner. Mortality and hatching inhibition caused by C. sativa were significantly higher than that of Z. alatum. Time duration also affected mortality and hatching inhibition significantly. Significant inhibition in invasion of M. incognita juveniles on cucumber cv. Royal Sluis was observed by different treatments with extracts. M. incognita juveniles exposed to 'S' extracts of C. sativa and Z. alatum for 24 and 48. h caused no infection. Exposure for 12 and 6. h caused more than 95 and 90% reductions in infectivity of M. incognita juveniles respectively. Similarly, soil drench and root dip treatments also caused significant reductions in infection. Reduction in infectivity was found to be significantly higher with extracts of C. sativa as compared to Z. alatum and decreased in a dose-responsive manner. The results of the studies showed that the extracts of test plants, commonly found locally, possess high potentials for the control of root-knot nematodes and could be the possible replacement for synthetic nematicides. © 2012 Elsevier B.V.

Peach fruit has become very popular among stone fruits in Pakistan with increasing production. The main area of peach production in Pakistan is Swat, in the northern part of the country. Significant fruit losses occur during harvest temporary storing, and transport to market. Objective of this study was to determine the effectiveness of salicylic acid (SA) at different concentrations (0, 0.5, 1.0, 1.5 or 2.0mmolL-1) on postharvest life of peach fruit (cv. 'Flordaking'). Fruits were treated with SA immediately after harvest and stored at 0°C for 5 weeks. Generally, all of the SA concentrations gave a higher activity of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) during five weeks of storage. The 2.0mmol SA concentrations showed the highest activity for enzymatic antioxidants. The fruit browning enzyme polyphenol oxidase (PPO) activity decreased in SA treated fruits. SA treated fruits exhibited higher radical scavenging activity (RSA) than control fruits. The SA 2.0mmol concentration resulted in increased fruit weight, firmness, and decreased juice pH. The higher concentration of SA (2.0mmol) proved to be the most effective in keeping peach fruit quality intact along with maintained skin color and delayed fruit surface decay during storage. Conclusively amongst all treatments SA 2.0mmol application exhibited maximum antioxidants enzymatic activities, minimum weight loss, stored firmness and decreased pH during storage period. © 2012 Elsevier B.V.

The objective of this study was to determine the distribution of somatotrophs and lactotrophs and conduct a morphometrical analysis of immunoreactive somatotrophs and lactotrophs in the pituitary glands of White Leghorn Hens (Gallus domesticus) during the period of induced moult. We divided the periods of induced moulting into three phases viz. 7, 14 and 21 days. The labeled alkaline-phsphatase method with anti-GH (growth hormone) and anti-PRL (prolactin) as a primary antibody was used to detect somatotrophs and lactotrophs, in the midsagital sections of chicken adenohypophysis. Immunohistochemistry showed that somatotrophs are not only confined to the cephalo-caudal axis but can also be found in the caudal lobe; while lactotrophs were distributed in both lobes of the anterior pituitary gland at all stages of moulting (7, 14 and 21 days). Lactotrophs were of different shapes but somatotrophs were oval to round in morphology. At the given stages of induced moulting, some hypertrophied lactotrophs were also present after 7 days of induced moult in the anterior pituitary gland. However, there were moulting-related changes: from 7 to 21 days of induced moulting the immunoreactive-PRL cell population decreased, while the mean lactotroph size was more than that of somatotrophs. Basic quantitative and morphological information relating to somatotrophs and lactotrophs during the period of induced moult in laying hens is reported here and the changes brought about by induced moulting are restricted to PRL positive cells rather than GH positive cells.

Abstract The objective of the present study was to prepare canola oil based vitamin E nanoemulsions by using food grade mixed surfactants (Tween:80 and lecithin; 3:1) to replace some concentration of nonionic surfactants (Tween 80) with natural surfactant (soya lecithin) and to optimize their preparation conditions. RBD (Refined, Bleached and Deodorized) canola oil and vitamin E acetate were used in water/vitamin E/oil/surfactant system due to their nutritional benefits and oxidative stability, respectively. Response surface methodology (RSM) was used to optimize the preparation conditions. The effects of homogenization pressure (75-155 MPa), oil concentrations (4-12% w/w), surfactant concentrations (3-11% w/w) and vitamin E acetate contents (0.4-1.2% w/w) on the particle size and emulsion stability were studied. RSM analysis has shown that the experimental data could be fitted well into second-order polynomial model with the coefficient of determinations of 0.9464 and 0.9278 for particle size and emulsion stability, respectively. The optimum values of independent variables were 135 MPa homogenization pressure, 6.18% oil contents, 6.39% surfactant concentration and 1% vitamin E acetate concentration. The optimized response values for particle size and emulsion stability were 150.10 nm and 0.338, respectively. Whereas, the experimental values for particle size and nanoemulsion stability were 156.13 ± 2.3 nm and 0.328 ± 0.015, respectively. © 2015 Elsevier Ltd. All rights reserved.

The importance of probiotics and their live delivery in the gastrointestinal tract has gained much importance in the recent past. Many reports have indicated that there is poor viability of probiotic bacteria in dairy based products, both fermented and non-fermented, and also in the human gastro-intestinal system is questionable. In this case, microencapsulation is the most significant emerging and efficient technology that is being used for the preservation of probiotics against adverse environmental conditions. Apart from different techniques of microencapsulation, various types of encapsulating materials are also used for the process, namely, alginate, chitosan, carrageenan, gums (locust bean, gellan gum, xanthan gum, etc.), gelatin, whey protein, starch, and compression coating. Each one of the encapsulating materials has its own unique characteristics of capsule formation and provision of shape, appearance, and strength to microbeads. The type of encapsulating material also influences the viability of probiotics during storage, processing, and in the gastrointestinal tract. The effectiveness of any material depends not upon its capsule forming capability, strength, and enhancing viability but also on its cheapness, availability, and biocompatibility. So, added convenience and reduced packaging costs may also be used to offset the cost of encapsulating one or more ingredients. Encapsulated forms of ingredients provide a longer shelf life for the product. © 2013 Copyright Taylor and Francis Group, LLC.
