Isoelectric focusing (IEF) profiles of pectate lyases (PLs) produced by five different groups of soft rot bacteria were analyzed by using the combined techniques of thin-layer polyacrylamide gel IEF and agarose-pectate overlay activity staining. Four strains of soft rot Erwinia spp. produced three or more PL isozymes. All of eight Pseudomonas viridiflava strains examined produced one single PL ...
Bacterial ring rot of potato is one of the most serious potato plant and tuber diseases. Laminaria japonica extract was investigated for its antimicrobial activity against Clavibater michiganense subsp. sepedonicum (Spieckermann & Kotthoff) Davis et al., the causative agent of bacterial ring rot of potato. The results showed that the optimum extraction conditions of antimicrobial substances fro...
Objective To analyse the frequency of reference rot in the journal Emergency Medicine Australasia, and to analyse the breakdown of rotten references into link rot and content drift. Method All URL References in the journal Emergency Medicine Australia between 2010 and 2014 were listed. These were then manually checked for link rot and content drift. A URL which suffered from either link rot or ...
A total of 91 isolates of probable antagonistic bacteria of potato soft rot bacterium Erwinia carotovora subsp. carotovora (Ecc) were extracted from rhizospheres and endophytes of various crop plants, different soil varieties, and atmospheres in the potato farming areas of Bangladesh. Antibacterial activity of the isolated probable antagonistic bacteria was tested in vitro against the previousl...
Basidiomycota (basidiomycetes) make up 32% of the described fungi and include most wood-decaying species, as well as pathogens and mutualistic symbionts. Wood-decaying basidiomycetes have typically been classified as either white rot or brown rot, based on the ability (in white rot only) to degrade lignin along with cellulose and hemicellulose. Prior genomic comparisons suggested that the two d...
Christy Hoepting, Cornell Cooperative Extension Regional Vegetable Program Steven Beer, Dept. of Plant Pathology and Plant-Microbe Biology, Cornell University It is important to emphasize that “exploring” is in the present tense. In New York, we are just beginning to delve into the fascinating relationship between nitrogen, plant spacing and bacterial diseases of onions. Our preliminary resul...
Plant defense responses to pathogen infection involve the production of active oxygen species, including hydrogen peroxide (H2O2). We obtained transgenic potato plants expressing a fungal gene encoding glucose oxidase, which generates H2O2 when glucose is oxidized. H2O2 levels were elevated in both leaf and tuber tissues of these plants. Transgenic potato tubers exhibited strong resistance to a...
استعدادیابی، فرایندی است که از طریق آن افرادی که بیشترین امید برای موفقیت آنها در آینده وجود دارد، شناسایی می¬شوند. در این پژوهش از 50 نفر (8 الی 10 سال) به عنوان نمونه آماری آزمون¬های استعدادیابی شامل ازرتسکی، پیکرسنجی، آمادگی جسمانی و حرکتی، آزمون¬های روانی و آزمون rot گرفته شد. در مرحله بعد این افراد در یک دوره¬ی سه ماهه آموزش بدمینتون شرکت کردند. در پایان این دوره برای شناسایی توانایی های م...
Laboratories use pigmentation, antibiotic susceptibility, and biochemical tests to identify anaerobic organisms that play a role in bovine interdigital necrobacillosis (bovine foot rot). In this study, 16S rRNA gene sequencing was used to identify strains to the species level that were originally classified as Prevotella or Porphyromonas spp by conventional phenotype assessment methods. Of 264 ...
Burkholderia glumae (bacterial grain rot), Xanthomonas oryzae pv. oryzae (bacterial leaf blight), and Acidovorax avenae subsp. avenae (bacterial brown stripe) are major seedborne pathogens of rice. Based on the 16S and 23S rDNA sequences for A. avenae subsp. avenae and B. glumae, and transposase A gene sequence for X. oryzae pv. oryzae, three sets of primers had been designed to produce 402 bp ...
