ABSTRACT-During rice growing season, the symptomless rice seeds from different paddy fields in Guilan province, Iran, were collected. After isolation of epiphytic and endophytic bacteria, 39 isolates including 19 epiphytes and 20 endophytes were selected based on the predominant characteristics. Five Operational Taxonomic Units (OTUs) were obtained based on PCR-RFLP of 16S r-DN...
BACKGROUND Exploring microorganisms especially bacteria associated with the degradation of lignocellulosic biomass shows great potentials in biofuels production. The rice endophytic bacterium Pantoea ananatis Sd-1 with strong lignocellulose degradation capacity has been reported in our previous study. However, a comprehensive analysis of its corresponding degradative system has not yet been con...
Center rot of onion, caused by Pantoea ananatis, is an economically important disease in onion production Georgia and elsewhere the United States. Growers rely on frequent foliar applications bactericides and, some cases, plant defense inducers to manage this disease. However, regular prophylactic application these chemicals not cost-effective may be environmentally friendly. Thrips (Thrips tab...
Species belonging to the genus of Pantoea are commonly isolated from plants, humans and the natural environment. The species of the genus are phenotypically closely related, making rapid identification of Pantoea strains to the species level difficult. Multilocus sequence analysis (MLSA) was evaluated as a means for rapid classification and identification of Pantoea strains. Four housekeeping g...
Onions (Allium cepa L.) are plagued by a number of bacterial pathogens including Pantoea ananatis, P. agglomerans, Burkholderia cepacia, Enterobacter cloacae, Pectobacterium carotovorum subsp. carotovorum, Xanthomonas axonopodis pv. axonopodis and several Pseudomonas spp. We developed a semi-selective medium, termed onion extract medium (OEM), to selectively and rapidly isolate bacteria pathoge...
گل و گیاهان زینتی در کلیه استان های کشور کشت شده و در قالب چهار گروه گل شاخه بریده، گل گلدانی، درخت و درختچه و گیاهان فصلی و نشائی طبقه بندی می شوند . کل سطح زیر کشت گیاهان زینتی در سال 1389 شامل مساحت گلخانه ها و فضای بسته معادل 47 میلیون متر مربع است که از این میزان 26 میلیون متر مربع به فضای آزاد 21 میلیون متر مربع به کشت گلخانه ای اختصاص دارد. این گیاهان مورد تهاجم عوامل بیماری زای مختلف، ش...
Obligate bacterial symbionts are widespread in many invertebrates, where they are often confined to specialized host cells and are transmitted directly from mother to progeny. Increasing numbers of these bacteria are being characterized but questions remain about their population structure and evolution. Here we take a comparative genomics approach to investigate two prominent bacterial symbion...
Pantoea ananatis is a member of the family Enterobacteriaceae and an enigmatic plant pathogen with a broad host range. Although P. ananatis strains can be aggressive on onion causing foliar necrosis and onion center rot, previous genomic analysis has shown that P. ananatis lacks the primary virulence secretion systems associated with other plant pathogens. We assessed a collection of fifty P. a...
