Network Store: Exploring Slicing in Future 5G Networks

In this paper, we present a revolutionary vision of 5G networks, in which SDN programs wireless network functions, and where Mobile Network Operators (MNO), Enterprises, and Over-The-Top (OTT) third parties are provided with NFV-ready Network Store. The proposed Network Store serves as a digital distribution platform of programmable Virtualized Network Functions (VNFs) that enable 5G application use-cases. Currently existing application stores, such as Apple's App Store for iOS applications, Google's Play Store for Android, or Ubuntu's Software Center, deliver applications to user specific software platforms. Our vision is to provide a digital marketplace, gathering 5G enabling Network Applications and Network Functions, written to run on top of commodity cloud infrastructures, connected to remote radio heads (RRH). The 5G Network Store will be the same to the cloud as the application store is currently to a software platform.

Benzoxazinoid Metabolites Regulate Innate Immunity against Aphids and Fungi in Maize

Benzoxazinoids (BXs), such as 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one (DIMBOA), are secondary metabolites in grasses. The first step in BX biosynthesis converts indole-3-glycerol phosphate into indole. In maize (Zea mays), this reaction is catalyzed by either BENZOXAZINELESS1 (BX1) or INDOLE GLYCEROL PHOSPHATE LYASE (IGL). The Bx1 gene is under developmental control and is mainly responsible for BX production, whereas the Igl gene is inducible by stress signals, such as wounding, herbivory, or jasmonates. To determine the role of BXs in defense against aphids and fungi, we compared basal resistance between Bx1 wild-type and bx1 mutant lines in the igl mutant background, thereby preventing BX production from IGL. Compared to Bx1 wild-type plants, BX-deficient bx1 mutant plants allowed better development of the cereal aphid Rhopalosiphum padi, and were affected in penetration resistance against the fungus Setosphaeria turtica. At stages preceding major tissue disruption, R. padi and S. turtica elicited increased accumulation of DIMBOA-glucoside, DIMBOA, and 2-hydroxy-4,7-dimethoxy-1,4-benzoxazin-3-one-glucoside (HDMBOA-glc), which was most pronounced in apoplastic leaf extracts. Treatment with the defense elicitor chitosan similarly enhanced apoplastic accumulation of DIMBOA and HDMBOA-glc, but repressed transcription of genes controlling BX biosynthesis downstream of BX1. This repression was also obtained after treatment with the BX precursor indole and DIMBOA, but not with HDMBOA-glc. Furthermore, BX-deficient bx1 mutant lines deposited less chitosan-induced callose than Bx1 wild-type lines, whereas apoplast infiltration with DIMBOA, but not HDMBOA-glc, mimicked chitosan-induced callose. Hence, DIMBOA functions as a defense regulatory signal in maize innate immunity, which acts in addition to its well-characterized activity as a biocidal defense metabolite.

Tracking the origins of Yakutian horses and the genetic basis for their fast adaptation to subarctic environments

Yakutia, Sakha Republic, in the Siberian Far East, represents one of the coldest places on Earth, with winter record temperatures dropping below -70 °C. Nevertheless, Yakutian horses survive all year round in the open air due to striking phenotypic adaptations, including compact body conformations, extremely hairy winter coats, and acute seasonal differences in metabolic activities. The evolutionary origins of Yakutian horses and the genetic basis of their adaptations remain, however, contentious. Here, we present the complete genomes of nine present-day Yakutian horses and two ancient specimens dating from the early 19th century and ∼5,200 y ago. By comparing these genomes with the genomes of two Late Pleistocene, 27 domesticated, and three wild Przewalski's horses, we find that contemporary Yakutian horses do not descend from the native horses that populated the region until the mid-Holocene, but were most likely introduced following the migration of the Yakut people a few centuries ago. Thus, they represent one of the fastest cases of adaptation to the extreme temperatures of the Arctic. We find cis-regulatory mutations to have contributed more than nonsynonymous changes to their adaptation, likely due to the comparatively limited standing variation within gene bodies at the time the population was founded. Genes involved in hair development, body size, and metabolic and hormone signaling pathways represent an essential part of the Yakutian horse adaptive genetic toolkit. Finally, we find evidence for convergent evolution with native human populations and woolly mammoths, suggesting that only a few evolutionary strategies are compatible with survival in extremely cold environments.

There is extensive variation in English dialects: this is why your answers to such questions will allow this app to localize your broader dialect region on a map of England. Did your home dialect change over time? Our algorithm is based on historical data from the Survey of English Dialects. If it guesses where you are from correctly, your home dialect has probably remained stable over the past decades. If the guess is far off, however, it is probably because of dialect change. - Can we localize your dialect based on your pronunciation of 26 words? - Record your dialect and listen to recordings of other users and to historical dialect recordings! - Choose a pronunciation variant, e.g. 'sheuf', and discover where in England it is used...or choose a place and explore its dialect!

Mechanisms and evolution of plant resistance to aphids

Aphids are important herbivores of both wild and cultivated plants. Plants rely on unique mechanisms of recognition, signalling and defence to cope with the specialized mode of phloem feeding by aphids. Aspects of the molecular mechanisms underlying aphid-plant interactions are beginning to be understood. Recent advances include the identification of aphid salivary proteins involved in host plant manipulation, and plant receptors involved in aphid recognition. However, a complete picture of aphid-plant interactions requires consideration of the ecological outcome of these mechanisms in nature, and the evolutionary processes that shaped them. Here we identify general patterns of resistance, with a special focus on recognition, phytohormonal signalling, secondary metabolites and induction of plant resistance. We discuss how host specialization can enable aphids to co-opt both the phytohormonal responses and defensive compounds of plants for their own benefit at a local scale. In response, systemically induced resistance in plants is common and often involves targeted responses to specific aphid species or even genotypes. As co-evolutionary adaptation between plants and aphids is ongoing, the stealthy nature of aphid feeding makes both the mechanisms and outcomes of these interactions highly distinct from those of other herbivore-plant interactions. © 2016 Macmillan Publishers Limited.

CHARACTERIZATION AND COMPARISON OF SUBHUMAN PRIMATE AND HUMAN TYPE C RETROVIRAL GENE PRODUCTS

The viral specific precursor polyproteins of simian sarcoma/simian associated virus (SiSV/SiAV), baboon endogenous viruses (BaEV), and three human isolate retroviruses, have been analyzed by radioimmunoprecipitation and tryptic peptide mapping. Cells infected with the BaEV isolates are characterized by identical precursor polyproteins: gPr80-85('env), Pr70-71('gag), and Pr65-67('gag). By tryptic digest mapping, m7-BaEV and 455K-BaEV were shown to be highly related. By comparison, mapping studies showed that BILN-BaEV was less highly related to m7-BaEV than was 455K-BaEV. Chase-incubated cells infected with BaEV also contained a stable, p28-related polyprotein termed P72('gag). This polyprotein appeared to arise by posttranslational modification of Pr70-71('gag). Tryptic digest mapping of BaEV and HL23V precursor polyproteins suggested that the BaEV-like component of HL23V was more closely related to m7-BaEV than to 455K-BaEV or BILN-BaEV.^ The intracellular precursor polyproteins of SiSV(SiAV) and gibbon ape leukemia virus (GaLV) were compared to the intracellular proteins of the human retrovirus isolates, HL23V, HEL12V, and A1476V. Cells infected with SiSV(SiAV) were characterized by polyproteins Pr200('gag-pol), gPr80('env), Pr80('gag), pr60('gag), and Pr40('gag). We have found that the human isolates are identical to true SiAV with regard to the size and structure of their precursor polyproteins. Both gPr80('env) and Pr60('gag) of SiAV were identical by tryptic peptide mapping to the respective proteins from the three human retroviral isolates examined. We have also shown that these viruses differ significantly from each of the GaLV isolates studied. Since SiAV differs substantially from any known GaLV isolate, we feel that it is unlikely that SiAV is a subtype of GaLV which exists today in the gibbon gene pool. The experimental evidence suggests that SiAV may be an exogenous human retrovirus that was transmitted originally into the human gene pool in the distant past by cross-species infection with GaLV(,SF) or with the GaLV(,SF) progenitor virus. It is, therefore, quite possible that SiAV expression in the pet woolly monkey arose from a recent infection of that monkey with SiAV from humans.^

Thinning Scab-resistant Apples with Liquid Lime Sulfur Sprays during Bloom

Growing scab-resistant apple cultivars on fully dwarfing rootstocks increases the feasibility for producing organically grown apples in the Midwest. However, in an organic orchard, fruit thinning to optimize crop load must be done by hand at a very high labor expense. The alternative is biennial bearing and inconsistent supply to meet consumer demands. Recently, sprays containing organicapproved materials such as liquid lime sulfur, fish, and various vegetable oils, salts, and kaolin have been tried alone or in combination for thinning apples with some degree of success. Lime sulfur alone or in combination with spray oil was recently labeled for use in Washington state orchards. This study was undertaken to evaluate the effectiveness of liquid lime sulfur alone and in combination with spray oil applied at various times during bloom on thinning three scab-resistant apple cultivars under Iowa conditions.

Influence of Crop Load on Tree Growth, Yield, and Fruit Quality of Scab Resistant Apples at Harvest

Apple scab, caused by Venturia inaequalis, is a major disease affecting apple production. Breeding programs have developed over 30 releases of scab-resistant cultivars since 1970 with recent ones having much improved quality. Redfree and GoldRush are from a cooperative breeding program involving Purdue, Rutgers, and Illinois universities while Liberty was introduced from the Cornell University breeding program. For these cultivars to gain better acceptance, more information is needed on their cropping capacities and the effect of crop load on fruit quality attributes. Our study was conducted to determine the relationship between increasing crop load on tree growth, fruit size, and fruit quality variables of the three cultivars under Iowa conditions.

Performance of Gibson Golden Delicious on Dwarfing Rootstocks

To evaluate the adaptability and performance of new and promising apple rootstocks in the dwarfing size-control category, a NC-140 regional rootstock trial was established in 2003 at 14 sites in the United States (AR, CA, IA, GA, KY, ME, MI, NY, OH, PA, UT, WI), Canada (BC), and Mexico. The Iowa planting, located at the ISU Horticulture Research Station, includes 23 rootstocks with new selections from the Cornell-Geneva breeding program (G, CG), Russia (Bud), Czech Republic (J-TE), Japan (JM), and Germany (PiAu) with M.26, M.9 Pajam 2, and M.9 T337 serving as industry standards. These rootstocks are being evaluated with Gibson Golden Delicious serving as the test cultivar. This report summarizes the tree-growth and production characteristics through the 2011 growing season.

Aphids in Corn Research

Corn, Zea mays L., is the most abundant field crop in Iowa, and there are many insect pests associated with this field crop. Although aphids are not typically economically important in corn, recent observations have indicated several aphid species developing heavy populations in northwest Iowa and southwest Minnesota. Historically, the corn leaf aphid, Rhopalosiphum maidis (Hemiptera: Aphididae), has been the most abundant aphid species in corn; however, the bird cherry oat aphid, R. padi (Hemiptera: Aphididae), and several other species have also been detected. Recent observations show a shift to populations peaking later in the summer. Damage potential and management guidelines for aphids in corn are not well defined and this research is aimed at developing economic threshold and sampling protocols.

Parches de vegetación arvense en una toposecuencia de altos y bajos en cultivos de manzanos : Mendoza (Argentina)

En un cultivo de manzanos en la provincia de Mendoza, Argentina, se observó la presencia de las comunidades dominadas por Cynodon dactylon y Galinsoga parviflora localizadas entre y bajo las copas de los árboles frutales, en coincidencia con una toposecuencia de relieves de altos y bajos, respectivamente. Ante el hecho de estar frente a un interesante ejemplo agronómico de establecimiento de comunidades arvenses se las analizó fisonómica, florística y sociológicamente, relacionándolas con las condiciones ecológicas, físico-químicas de los suelos y bioclimáticas de los sitios que las contienen. Mientras la comunidad de Cynodon dactylon presente en los altos o entre plantas resultó más luminosa, cálida, seca y menos fértil, la de Galinsoga parviflora en los bajos fue más sombría, fría, húmeda y más fértil. En esta última, la alta concentración de materia orgánica, nutrientes minerales y humedad de los suelos parece estar relacionada con la presencia de plantas anuales bajo las copas. Los resultados obtenidos muestran la importancia de las toposecuencias de relieves de altos y bajos en la distribución, estructura y composición florística de las comunidades vegetales arvenses, las cuales pueden resultar potenciadas con las coberturas de las copas de los árboles frutales.

Evaluación de extractos cetónicos de paraíso, eucalipto y ricino sobre Myzus persicae (Homoptera: Aphididae)

En el cultivo de pimiento, Myzus persicae es una plaga cuyo manejo se basa en el uso de agroquímicos de síntesis. Una alternativa de menor impacto ambiental para su control es la aplicación de extractos naturales. El objetivo del trabajo fue evaluar el efecto de extractos provenientes de Melia azedarach, Eucalyptus globulus y Ricinus communis sobre este pulgón. Se escogió la técnica del film residual en papel de filtro, manteniendo los individuos sobre hojas de pimiento ornamental. Se utilizaron extractos acetónicos a una dilución de 10 000 ppm, con 5 individuos en cada una de las 10 réplicas de los tratamiento. Se efectuaron lecturas para mortalidad a los 30 minutos y 24, 48 y 72 horas. Los resultados se analizaron mediante ANOVA de medidas repetidas y prueba de Tukey. El extracto de eucalipto produjo una mortalidad significativa, alcanzando un máximo cercano al 50 % en promedio, para la lectura a las 72 horas. Asimismo se observó un efecto sobre la reproducción, generado por los extractos de eucalipto y ricino, aunque no pudo probarse esto estadísticamente. Para el ricino, se infiere un probable efecto de repelencia. Se propone continuar con los ensayos de extractos, ampliando la evaluación de su efecto sobre el potencial reproductivo del organismo blanco.

Aspectos biológicos y poblacionales de Sipha Maydis (Passerini) y Schizaphis Graminum (Rondani) en cebada

El objetivo del presente estudio fue obtener los parámetros bioetológicos de Sipha maydis (Passerini) y Schizaphis graminum (Rondani) sobre cebada, Hordeum vulgare L. cv. Pampa. Los pulgones se criaron en condiciones de laboratorio a 20±1 °C, 14:10 horas de fotofase y una humedad relativa del 50-70 %. Se obtuvieron cohortes a partir de poblaciones de estos áfidos, sobre las que se realizó el registro diario de los cambios de estado, número de individuos muertos y los nacimientos una vez alcanzado el estado adulto. Se analizaron las curvas de supervivencia por edades (lx) y fecundidad (mx) y los siguientes estadísticos vitales: tasa reproductiva neta (Ro); tasa intrínseca de crecimiento natural (rm); tiempo generacional medio (T) y tiempo de duplicación (D). Para la comparación de las rm se obtuvieron las rm estimadas junto con su error standard mediante el procedimiento <jackknife». Si bien el pulgón verde de los cereales S. graminum posee mayor eficiencia reproductiva, S. maydis presenta valores de supervivencia y fecundidad de importancia, que indicaría que este áfido podría constituirse en una plaga potencial de gramíneas cultivadas.

Sarna del manzano : detección de la forma sexual (Venturia inaequalis ) en Mendoza (Argentina)

El aumento de los daños provocados por la sarna del manzano [Fusicladium dendritichum (Wallr.) Fuckl.] en montes frutales de Mendoza (Argentina), motivó estudios para aclarar la biología del hongo y buscar la presencia de la forma sexual, no detectada aún en la provincia. Al momento de la brotación se muestrearon hojas del año anterior que se encontraban en el suelo de dichos montes. En el laboratorio fueron observadas bajo estereomicroscopio. Los cuerpos negros inmersos en el tejido de la hoja fueron montados en preparados microscópicos y observados para establecer su identidad. Se confirmó la presencia en la zona de la forma teleomórfica del agente causal de la sarna del manzano. Este hecho tiene importancia en la epidemiología de la enfermedad y en las estrategias de control.
