Potato ( Solanum tuberosum L ) is affected by several viral pathogens with the most economically damaging being potato virus Y (PVY). At least nine biologically distinct variants of PVY are known to attack potato, necrotic types named NTN and N-Wi recent additions list. So far, molecular plant-virus interactions underlying this pathogenicity not fully understood. In study, gas chromatography coupled mass spectroscopy (GC–MS) was used for an untargeted investigation changes in leaf...
Abstract Despite advances in antiretroviral therapy that have revolutionized HIV-1 disease management, effective control of the infection pandemic remains elusive. Increased rates and genetic diversity Sub-Saharan African countries pose a challenge clinical management. This study provides picture its implications for spread effectiveness therapies Africa. Whole-genome sequences were obtained from Genbank using accession numbers 10 with high prevalence. Alignment composed query reference...
Potato virus Y (PVY) is one of the most economically important pathogen potato that present as biologically distinct strains. The virus-derived small interfering RNAs (vsiRNAs) from cv. Russet Burbank individually infected with PVY-N, PVY-NTN and PVY-O strains were recently characterized. Plant defense RNA-silencing mechanisms deployed against viruses produce vsiRNAs to degrade homologous viral transcripts. Based on sequence complementarity, can potentially host RNA transcripts raising...
Abstract Dahlia mosaic virus (DMV), an aphid‐transmitted caulimovirus in the family Caulimoviridae , is important pathogen of dahlia ( variabilis ). Development rapid, and sensitive diagnostic tools essential surveillance management DMV. A loop‐mediated isothermal amplification (LAMP) assay was developed for DMV detection. The LAMP targets reverse transcriptase region genome optimal at a temperature 60°C run time 60 min, detected through fluorescence detection by agarose gel electrophoresis....
Abstract Phytophthora cinnamomi is an important soilborne pathogen causing root rot and stem cankers on macadamia in South Africa other countries. It unknown whether a temporal pattern exists the colonization of tree roots by P . To investigate this, three orchards were studied bimonthly for 2 years. The study also examined two types feeder contained varying levels P. DNA. A new sensitive ‐specific quantitative real‐time PCR (qPCR) assay was used to conduct assessments. Only symptomatic...
Woodland ecosystems are integral and crucial to biodiversity neighbouring human communities. These have experienced vast changes in their physical nature which affect the roles they play, as urban expansion, agriculture, wood fuel collection open-air churches all result clearing of woody vegetation. Remote sensing geographic information system techniques used assess vegetation over a 20-year period (1990–2010) around Bulawayo. Three Bulawayo's woodland areas (Richmond, Pumula Bellevue) were...
Abstract. For service providers developing commercial value-added data content based on remote sensing technologies, the focus is to typically create commercially appropriate geospatial information which has downstream business value. The primary aim being link locational intelligence with in order better make informed decisions. From a perspective this must be relevant, informative, and most importantly current; ability maintain timeously into future for change detection purposes. Aligned...
There has been an explosion in the number of wireless devices and deployment networks. Successful networks depends on proper planning design. One important aspects during phase is to determine extent at which diffraction (scatter) reflection propagated signals influence path loss. The best way do so, model signal's loss as it travels from emitter receiver. In this work we propose a predict for based radiosity method commonly implemented quest realism representing images computer graphics...
