• Histone H3K9 and H3K27 Methylation Regulates Fungal Alkaloid Biosynthesis in a Fungal Endophyte‐Plant Symbiosis

    Updated: 2014-02-28 02:25:28
    Summary Epichloë festucae is a filamentous fungus that forms a mutually beneficial symbiotic association with Lolium perenne. This endophyte synthesizes bioprotective lolitrems (ltm) and ergot alkaloids (eas) in planta but the mechanisms regulating expression of the corresponding sub‐telomeric gene clusters are not known. We show here that the status of histone H3 lysine 9 and lysine 27 trimethylation (H3K9me3/H3K27me3) at these alkaloid gene loci are critical determinants of transcriptional activity. Using ChIP‐qPCR we found that levels of H3K9me3 and H3K27me3 were reduced at these loci in plant infected tissue compared to axenic culture. Deletion of E. festucae genes encoding the H3K9‐ (ClrD) or H3K27‐ (EzhB) methyltransferases led to derepression of ltm and eas gene expression ...

    Updated: 2014-02-26 23:00:00
    Conclusions: The KU70-deficient mutant generated herein was effective in improving gene deletion frequency and allowed shorter homology sequences to be used for gene targeting. It retained the key oleaginous and fast growing features of R. toruloides. The strain should facilitate both fundamental and applied studies in this important yeast, with the approaches taken here likely to be applicable in other species in subphylum Pucciniomycotina.

  • Occurrence and distribution of Vibrio vulnificus and Vibrio parahaemolyticus – potential roles for fish, oyster, sediment and water

    Updated: 2014-02-26 23:00:00
    Abstract Vibrio vulnificus and Vibrio parahaemolyticus are Gram‐negative marine bacteria naturally found in estuaries such as the Gulf of Mexico and can be pathogenic to humans. We quantified both of these organisms in fish, oyster, sediment, and water using culture‐independent (quantitative PCR; qPCR) and culture‐dependent (direct plating‐colony hybridization; DP‐CH) techniques during the transition period between winter and spring. We correlated these levels to environmental conditions and to abundance of total bacteria and total vibrio. By qPCR, fish intestine samples had the highest V. vulnificus densities and were 2·7, 3·5, and 4·2 logs greater than oyster, sediment and water samples, respectively. Densities of V. parahaemolyticus in fish samples by qPCR were 1·0, 2·1...

  • The inner membrane complex through development of Toxoplasma gondii and Plasmodium

    Updated: 2014-02-26 14:48:03
    Summary Plasmodium spp and Toxoplasma gondii are important human and veterinary pathogens. These parasites possess an unusual double membrane structure located directly below the plasma membrane named the inner membrane complex (IMC). First identified in early electron micrograph studies, huge advances in genetic manipulation of the Apicomplexa have allowed the visualisation of a dynamic, highly structured cellular compartment with important roles in maintaining the structure and motility of these parasites. This review summarises recent advances in the field and highlights the changes the IMC undergoes during the complex life cycles of the Apicomplexa. (Source: Cellular Microbiology)

  • Toxin–antitoxin vapBC locus participates in formation of the dormant state in Mycobacterium smegmatis

    Updated: 2014-02-25 23:00:00
    Abstract Toxin–antitoxin (TA) loci are widely spread in bacterial plasmids and chromosomes. Toxins affect important functions of bacterial cells such as translation, replication and cell‐wall synthesis, whereas antitoxins are toxin inhibitors. Participation in formation of the dormant state in bacteria is suggested to be a possible function of toxins. Here we show that overexpression of VapC toxin in Mycobacterium smegmatis results in development of morphologically distinct ovoid cells. The ovoid cells were nonreplicating and revealed a low level of uracil incorporation and respiration that indicated their dormant status. To validate the role of VapBC in dormancy formation, we used a model of dormant, ‘nonculturable' (NC) M. smegmatis cells obtained in potassium‐limited conditions...

  • Fitness costs of rifampicin resistance in Mycobacterium tuberculosis are amplified under conditions of nutrient starvation and compensated by mutation in the β′ subunit of RNA polymerase

    Updated: 2014-02-25 23:00:00
    Summary Rifampicin resistance, a defining attribute of multidrug‐resistant tuberculosis, is conferred by mutations in the β subunit of RNA polymerase. Sequencing of rifampicin‐resistant (RIF‐R) clinical isolates of Mycobacterium tuberculosis revealed, in addition to RIF‐R mutations, enrichment of potential compensatory mutations around the double‐psi β‐barrel domain of the β′ subunit comprising the catalytic site and the exit tunnel for newly synthesized RNA. Sequential introduction of the resistance allele followed by the compensatory allele in isogenic Mycobacterium smegmatis showed that these mutations respectively caused and compensated a starvation enhanced growth defect by altering RNA polymerase activity. While specific combinations of resistance and compensatory al...

  • The carrying pigeons of the cell: exosomes and their role in infectious diseases caused by human pathogens

    Updated: 2014-02-23 23:00:00
    Abstract Exosomes have recently been classified as the newest family members of ‘bioactive vesicles’ that function to promote intercellular communication. Long ignored and thought to be only a mechanism by which cellular waste is removed, exosomes have garnered a huge amount of interest in recent years as their critical functions in maintaining homeostasis through intercellular communication and also in different types of diseases have been demonstrated. Many groundbreaking studies of exosome functions have been performed in the cancer field and the infectious disease areas of study, revealing the importance and also the fascinating complexity of exosomal packaging, targeting, and functions. Selective packaging of exosomes in response to the type of infection, exosomal modulation of th...

  • Reversal of Mycobacterium tuberculosis phenotypic drug resistance by 2‐aminoimidazole‐based small molecules

    Updated: 2014-02-23 23:00:00
    Abstract The expression of phenotypic drug resistance or drug tolerance serves as a strategy for Mycobacterium tuberculosis to survive in vivo antimicrobial drug treatment; however, the mechanisms are poorly understood. Progress toward a more in depth understanding of in vivo drug tolerance and the discovery of new therapeutic strategies designed specifically to treat drug‐tolerant M. tuberculosis are hampered by the lack of appropriate in vitro assays. A library of 2‐aminoimidazole‐based small molecules combined with the antituberculosis drug isoniazid was screened against M. tuberculosis expressing in vitro drug tolerance as microbial communities attached to an extracellular matrix derived from lysed leukocytes. Based on the ability of nine of ten 2‐aminoimidazole compounds to ...

  • HspX vaccination and role in virulence in the guinea pig model of tuberculosis

    Updated: 2014-02-23 23:00:00
    In this report, three HspX formulas (native and two recombinant variants) were used as vaccines in the guinea pig model of tuberculosis; none were protective during challenge with WT Mtb. However, recombinant HspX was protective in animals challenged with a strain of Mtb lacking hspX (X4‐19), indicating protection was driven by molecules co‐purifying with HspX or an adjuvant effect of recombinant HspX in this system. Mtb X4‐19 was significantly less virulent than WT Mtb. Quantitative PCR and whole genome sequencing identified several genes (Rv2030c‐Rv2032, Rv1062, Rv1771, Rv1907, and Rv3479) with altered expression that may contribute to loss of virulence. Physiological differences required for the establishment of Mtb infection in different hosts may affect the potential of subuni...

  • BrlR from Pseudomonas aeruginosa is a c‐di‐GMP‐responsive transcription factor

    Updated: 2014-02-23 23:00:00
    Abstract The transcriptional regulator BrlR is a member of the MerR family of multidrug transport activators that contributes to the high‐level drug tolerance of Pseudomonas aeruginosa biofilms. While MerR regulators are known to activate both the expression of multidrug efflux pump genes and their own transcription upon inducer‐binding, little is known about BrlR activation. We demonstrate using promoter reporter strains, in vivo and in vitro DNA‐binding assays combined with 5'RACE, that BrlR binds to its own promoter, likely via a MerR‐like palindromic sequence. Unlike known MerR multidrug transport activators, BrlR and brlR expression are not activated by multidrug transporter substrates. Instead, BrlR‐DNA binding was enhanced by the secondary messenger c‐di‐GMP. In additi...

  • Rapid and sensitive detection of Phytophthora colocasiae responsible for the taro leaf blight using conventional and real‐time PCR assay

    Updated: 2014-02-23 23:00:00
    Abstract Conventional and real‐time PCR assays were developed for sensitive and specific detection of Phytophthora colocasiae, an oomycete pathogen that causes leaf blight and corm rot of taro. A set of three primer pairs was designed from regions of the RAS‐related protein (Ypt1), G protein alpha‐subunit (GPA1) and phospho‐ribosylanthranilate isomerase (TRP1) genes. In conventional PCR, the lower limit of detection was 50 pg DNA, whereas in real‐time PCR, the detection limit was 12.5 fg for the primer based on Ypt1 gene. The cycle threshold values were linearly correlated with the concentration of the target DNA (range of R2 = 0.911–0.999). All the primer sets were successful in detecting P. colocasie from naturally infected leaves and tubers of taro. Phytophthora colocas...
