| genome sequence of a carbapenem-resistant strain of ralstonia mannitolilytica. | ralstonia mannitolilytica, a gram-negative aerobic bacterium, is an opportunistic human pathogen that is becoming more common in cases of nosocomial infections. we report for the first time the whole-genome sequence analysis of r. mannitolilytica strain mry14-0246, which carries the intrinsic oxa-443/oxa-22-like and oxa-444/oxa-60-like β-lactamase genes and is resistant to meropenem. | 2015 | 25953190 |
| naturally occurring diversity helps to reveal genes of adaptive importance in legumes. | environmental changes challenge plants and drive adaptation to new conditions, suggesting that natural biodiversity may be a source of adaptive alleles acting through phenotypic plasticity and/or micro-evolution. crosses between accessions differing for a given trait have been the most common way to disentangle genetic and environmental components. interestingly, such man-made crosses may combine alleles that never meet in nature. another way to discover adaptive alleles, inspired by evolution, ... | 2015 | 25954294 |
| role of elicitors in inducing resistance in plants against pathogen infection: a review. | disease control is largely based on the use of fungicides, bactericides, and insecticides-chemical compounds toxic to plant invaders, causative agents, or vectors of plant diseases. however, the hazardous effect of these chemicals or their degradation products on the environment and human health strongly necessitates the search for new, harmless means of disease control. there must be some natural phenomenon of induced resistance to protect plants from disease. elicitors are compounds, which act ... | 2013 | 25969762 |
| prhn, a putative marr family transcriptional regulator, is involved in positive regulation of type iii secretion system and full virulence of ralstonia solanacearum. | the marr-family of transcriptional regulators are involved in various cellular processes, including resistance to multiple antibiotics and other toxic chemicals, adaptation to different environments and pathogenesis in many plant and animal pathogens. here, we reported a new marr regulator prhn, which was involved in the pathogenesis of ralstonia solanacearum. prhn mutant exhibited significantly reduced virulence and stem colonization compared to that of wild type in tomato plants. prhn mutant c ... | 2015 | 25972849 |

| involvement of aph(3')-iia in the formation of mosaic aminoglycoside resistance genes in natural environments. | intragenic recombination leading to mosaic gene formation is known to alter resistance profiles for particular genes and bacterial species. few studies have examined to what extent aminoglycoside resistance genes undergo intragenic recombination. we screened the genbank database for mosaic gene formation in homologs of the aph(3')-iia (nptii) gene. aph(3')-iia inactivates important aminoglycoside antibiotics. the gene is widely used as a selectable marker in biotechnology and enters the environm ... | 2015 | 26042098 |
| microbial effectors target multiple steps in the salicylic acid production and signaling pathway. | microbes attempting to colonize plants are recognized through the plant immune surveillance system. this leads to a complex array of global as well as specific defense responses, which are often associated with plant cell death and subsequent arrest of the invader. the responses also entail complex changes in phytohormone signaling pathways. among these, salicylic acid (sa) signaling is an important pathway because of its ability to trigger plant cell death. as biotrophic and hemibiotrophic path ... | 2015 | 26042138 |
| burkholderia cenocepacia lipopolysaccharide modification and flagellin glycosylation affect virulence but not innate immune recognition in plants. | burkholderia cenocepacia causes opportunistic infections in plants, insects, animals, and humans, suggesting that "virulence" depends on the host and its innate susceptibility to infection. we hypothesized that modifications in key bacterial molecules recognized by the innate immune system modulate host responses to b. cenocepacia. indeed, modification of lipopolysaccharide (lps) with 4-amino-4-deoxy-l-arabinose and flagellin glycosylation attenuates b. cenocepacia infection in arabidopsis thali ... | 2015 | 26045541 |
| plant expansins: diversity and interactions with plant cell walls. | expansins were discovered two decades ago as cell wall proteins that mediate acid-induced growth by catalyzing loosening of plant cell walls without lysis of wall polymers. in the interim our understanding of expansins has gotten more complex through bioinformatic analysis of expansin distribution and evolution, as well as through expression analysis, dissection of the upstream transcription factors regulating expression, and identification of additional classes of expansin by sequence and struc ... | 2015 | 26057089 |
| validation and application of a real-time pcr protocol for the specific detection and quantification of clavibacter michiganensis subsp. sepedonicus in potato. | clavibacter michiganensis subsp. sepedonicus (cms) multiplies very rapidly, passing through the vascular strands and into the stems and petioles of a diseased potato. therefore, the rapid and specific detection of this pathogen is highly important for the effective control of the pathogen. although several pcr assays have been developed for detection, they cannot afford specific detection of cms. therefore, in this study, a computational genome analysis was performed to compare the sequenced gen ... | 2015 | 26060431 |
| strategies and approaches in plasmidome studies-uncovering plasmid diversity disregarding of linear elements? | the term plasmid was originally coined for circular, extrachromosomal genetic elements. today, plasmids are widely recognized not only as important factors facilitating genome restructuring but also as vehicles for the dissemination of beneficial characters within bacterial communities. plasmid diversity has been uncovered by means of culture-dependent or -independent approaches, such as endogenous or exogenous plasmid isolation as well as pcr-based detection or transposon-aided capture, respect ... | 2015 | 26074886 |

| bean 2.0: an integrated web resource for the identification and functional analysis of type iii secreted effectors. | gram-negative pathogenic bacteria inject type iii secreted effectors (t3ses) into host cells to sabotage their immune signaling networks. because t3ses constitute a meeting-point of pathogen virulence and host defense, they are of keen interest to host-pathogen interaction research community. to accelerate the identification and functional understanding of t3ses, we present bean 2.0 as an integrated web resource to predict, analyse and store t3ses. bean 2.0 includes three major components. first ... | 2015 | 26120140 |
| ohr protects corynebacterium glutamicum against organic hydroperoxide induced oxidative stress. | ohr, a bacterial protein encoded by the organic hydroperoxide resistance (ohr) gene, plays a critical role in resistance to organic hydroperoxides. in the present study, we show that the cys-based thiol-dependent ohr of corynebacterium glutamicum decomposes organic hydroperoxides more efficiently than hydrogen peroxide. replacement of either of the two cys residues of ohr by a ser residue resulted in drastic loss of activity. the electron donors supporting regeneration of the peroxidase activity ... | 2015 | 26121694 |
| motility, chemotaxis and aerotaxis contribute to competitiveness during bacterial pellicle biofilm development. | biofilm formation is a complex process involving various signaling pathways and changes in gene expression. many of the sensory mechanisms and regulatory cascades involved have been defined for biofilms formed by diverse organisms attached to solid surfaces. by comparison, our knowledge on the basic mechanisms underlying the formation of biofilms at air-liquid interfaces, that is, pellicles, is much less complete. in particular, the roles of flagella have been studied in multiple solid-surface b ... | 2015 | 26122431 |
| xanthomonas campestris pv. vesicatoria secretes proteases and xylanases via the xps type ii secretion system and outer membrane vesicles. | many plant-pathogenic bacteria utilize type ii secretion (t2s) systems to secrete degradative enzymes into the extracellular milieu. t2s substrates presumably mediate the degradation of plant cell wall components during the host-pathogen interaction and thus promote bacterial virulence. previously, the xps-t2s system from xanthomonas campestris pv. vesicatoria was shown to contribute to extracellular protease activity and the secretion of a virulence-associated xylanase. the identities and funct ... | 2015 | 26124239 |
