<P>Hyperhydric disorders occur frequently in plant tissues cultured in vitro and cause several morphological and physiological abnormalities. However, a systematic defense response is triggered by hyperhydric conditions. The accumulation of reactive oxygen species (ROS), activities of antioxidant enzymes and their immunoblots, and the proteome-level changes in normal versus hyperhydric shoots of carnation (Dianthus caryophyllus) cultured in vitro were investigated. Total proteins were also extracted from the shoot and analyzed by two-dimensional electrophoresis. Among a total of 700 spots detected, only 40 had significant changes in abundance in the hyperhydric compared to the normal shoots, which were further identified by a mass spectrometer (MALDI-TOF MS). Most of them were involved in photosynthesis, RNA processing, and general metabolisms, while the rest were involved in secondary metabolic processes. These identified proteins in carnation shoots may provide novel evidences for stress tolerance against hyperhydricity.</P>

<P>The objective of this study was to investigate the response of light emitting diodes (LEDs) at different light intensities (70 and 80 for green LEDs, 88 and 238 for red LEDs and 80 and 238 μmol m<SUP>−2</SUP> s<SUP>−1</SUP> for blue LEDs) at three wavelengths in lettuce leaves. Lettuce leaves were exposed to (522 nm), red (639 nm) and blue (470 nm) LEDs of different light intensities. Thylakoid multiprotein complex proteins and photosynthetic metabolism were then investigated. Biomass and photosynthetic parameters increased with an increasing light intensity under blue LED illumination and decreased when illuminated with red and green LEDs with decreased light intensity. The expression of multiprotein complex proteins including PSII-core dimer and PSII-core monomer using blue LEDs illumination was higher at higher light intensity (238 μmol m<SUP>−2</SUP> s<SUP>−1</SUP>) and was lowered with decreased light intensity (70–80 μmol m<SUP>−2</SUP> s<SUP>−1</SUP>). The responses of chloroplast sub-compartment proteins, including those active in stomatal opening and closing, and leaf physiological responses at different light intensities, indicated induced growth enhancement upon illumination with blue LEDs. High intensity blue LEDs promote plant growth by controlling the integrity of chloroplast proteins that optimize photosynthetic performance in the natural environment.</P>
Integrating E-Govemment Services in Palestine: Organizational Interoperability Perspective
( Muneer Dawahqa ) 한국정책학회 2015 한국정책학회 동계학술발표논문집 Vol.2015 No.-
Enabling electronic Governments (e-Government) systems to interoperate provides many benefits, including improved efficiency, transparency, accountability, and access, as well as coordination of services at lower costs. The major challenge when integrating information systems in any domain such as e-Government is the challenge of interoperability in government organizations, information systems often handle sensitive data about individuals and other organizations using various kinds of identifiers. The growing cooperation of organizations results in the need to share and exchange such data. Interoperability between organizations is influenced by three layers of interoperability (i.e., technical, semantic, & organizational interoperability). This research will focus on the most challenging factors of organizational interoperability because this level is the most difficult layer and lower layers like technical and semantic interoperability have been talked by many standards. In this research I will develop a new model to deal with organization interoperability which will discuss all the factors that affect the Organizational interoperability, these factors will be determined in this study by doing qualitative method using previous research reviews in the literature and then determine these factors that affect the organizational interoperability and then discussion and analysis of these issues.

A model is presented in this paper to provide understanding of the supply chain integration and supply chain information practices' impact on the manufacturing industries. The supply chain information practices play a crucial role in sharing information between the members of SC network. Thus, it is important to develop a comprehensive understanding of the differences and similarities among ISI and information management. It will allow firms to systematically evaluate and carefully choose the information strategy. The empirical findings of this research offer essential and interesting insights about what role SCI, supply chain information and Supply chain ISI play in determining Malaysia's financial performance. The theoretical gaps addressed in this study are of significant importance, since a little empirical evidence is available regarding system infrastructure and supply chain information management's effectiveness. This research provides further paths of exploring system infrastructure and information management, thereby defining the manufacturing industries' next step in SCM struggle i.e. modifying total integrated SC principle in other manufacturing firms. The Resource-based theory discovered organizational resources as an essential organizational success ingredient. Therefore, in order to recognize its potential value, internal resources, for instance, information system and management must be fully utilized.

<P>Tomato plants often grow in saline environments in Mediterranean countries where salt accumulation in the soil is a major abiotic stress that limits its productivity. However, silicon (Si) supplementation has been reported to improve tolerance against several forms of abiotic stress. The primary aim of our study was to investigate, using comparative physiological and proteomic approaches, salinity stress in chloroplasts of tomato under silicon supplementation. Tomato seedlings (<I>Solanum lycopersicum</I> L.) were grown in nutrient media in the presence or absence of NaCl and supplemented with silicon for 5 days. Salinity stress caused oxidative damage, followed by a decrease in silicon concentrations in the leaves of the tomato plants. However, supplementation with silicon had an overall protective effect against this stress. The major physiological parameters measured in our studies including total chlorophyll and carotenoid content were largely decreased under salinity stress, but were recovered in the presence of silicon. Insufficient levels of net-photosynthesis, transpiration and stomatal conductance were also largely improved by silicon supplementation. Proteomics analysis of chloroplasts analyzed by 2D-BN-PAGE (second-dimensional blue native polyacrylamide-gel electrophoresis) revealed a high sensitivity of multiprotein complex proteins (MCPs) such as photosystems I (PSI) and II (PSII) to the presence of saline. A significant reduction in cytochrome <I>b6</I>/<I>f</I> and the ATP-synthase complex was also alleviated by silicon during salinity stress, while the complex forms of light harvesting complex trimers and monomers (LHCs) were rapidly up-regulated. Our results suggest that silicon plays an important role in moderating damage to chloroplasts and their metabolism in saline environments. We therefore hypothesize that tomato plants have a greater capacity for tolerating saline stress through the improvement of photosynthetic metabolism and chloroplast proteome expression after silicon supplementation.</P>

<P>To investigate Fe deficiency tolerance in tomato cultivars, quantification of proteins and genes involved in Fe metabolism and antioxidant mechanisms were performed in “Roggusanmaru” and “Super Doterang”. Fe deficiency (Moderate, low and –Fe) significantly decreased the biomass, total, and apoplastic Fe concentration of “Roggusanmaru”, while a slight variation was observed in “Super Doterang” cultivar. The quantity of important photosynthetic pigments such as total chlorophyll and carotenoid contents significantly decreased in “Roggusanmaru” than “Super Doterang” cultivar. The total protein profile in leaves and roots determines that “Super Doterang” exhibited an optimal tolerance to Fe deficiency compared to “Roggusanmaru” cultivar. A reduction in expression of PSI (photosystem I), PSII (photosystem II) super-complexes and related thylakoid protein contents were detected in “Roggusanmaru” than “Super Doterang” cultivar. Moreover, the relative gene expression of <I>SlPSI</I> and <I>SlPSII</I> were well maintained in “Super Doterang” than “Roggusanmaru” cultivar. The relative expression of genes involved in Fe-transport (<I>SlIRT1</I> and <I>SlIRT2</I>) and Fe(III) chelates reductase oxidase (<I>SlFRO1</I>) were relatively reduced in “Roggusanmaru”, while increased in “Super Doterang” cultivar under Fe deficient conditions. The H<SUP>+</SUP>-ATPase relative gene expression (<I>SlAHA1</I>) in roots were maintained in “Super Doterang” compared to “Roggusanmaru”. Furthermore, the gene expressions involved in antioxidant defense mechanisms (<I>SlSOD</I>, <I>SlAPX</I> and <I>SlCAT</I>) in leaves and roots showed that these genes were highly increased in “Super Doterang”, whereas decreased in “Roggusanmaru” cultivar under Fe deficiency. The present study suggested that “Super Doterang” is better tomato cultivar than “Roggusanmaru” for calcareous soils.</P>
