1.[Agrobacterium tumefaciens-mediated transformation of Aureobasidium pullulans and high-efficient screening for polymalic acid producing strain].
Tu G, Wang Y, Feng J, Li X, Guo M, Zou X. Sheng Wu Gong Cheng Xue Bao. 2015 Jul;31(7):1063-72.
To develop a genetic transformation method of Aureobasidium pullulans and T-DNA insertion for high-efficient screening of polymalic acid (PMA) producing strain. Agrobacterium tumefaciens-AGL1, containing the selection genes encoding hygromycin B phosphotase or phosphinothricin acetyltranferase, was used to transform Aureobasidium pullulans CCTCC M2012223 and transformants were confirmed by colony PCR method. Transferred DNA (T-DNA) insertional mutants were cultured in microwell plate, and screened for high-titer PMA producing strain according to the pH response model. DNA walking was used to detect the insertion sites in the mutant. Results show that the selection markers could stably generated in the transformants, and 80 to 120 transformants could be found per 10(7) single cells. A high-titer PMA mutant H27 was obtained, giving a good PMA production caused by the disruption of phosphoglycerate mutase, that increased by 24.5% compared with the control.
2.Apramycin treatment affects selection and spread of a multidrug-resistant Escherichia coli strain able to colonize the human gut in the intestinal microbiota of pigs.
Herrero-Fresno A1, Zachariasen C2, Hansen MH3, Nielsen A4, Hendriksen RS5, Nielsen SS6, Olsen JE7. Vet Res. 2016 Jan 7;47(1):12. doi: 10.1186/s13567-015-0291-z.
The effect of apramycin treatment on transfer and selection of an Escherichia coli strain (E. coli 912) in the intestine of pigs was analyzed through an in vivo experiment. The strain was sequenced and assigned to the sequence type ST101 and serotype O11. It carried resistance genes to apramycin/gentamicin, sulphonamide, tetracycline, hygromycin B, β-lactams and streptomycin [aac(3)-IV, sul2, tet(X), aph(4), bla TEM-1 and strA/B], with all but tet(X) located on the same conjugative plasmid. Nineteen pigs were randomly allocated into two inoculation groups, one treated with apramycin (pen 2) and one non-treated (pen 3), along with a non-inoculated control group (pen 1). Two pigs of pen 2 and 3 were inoculated intragastrically with a rifampicin resistant variant of the strain. Apramycin treatment in pen 2 was initiated immediately after inoculation. Strain colonization was assessed in the feces from all pigs. E. coli 912 was shown to spread to non-inoculated pigs in both groups.
3.Functional Dissection of the Nascent Polypeptide-Associated Complex in Saccharomyces cerevisiae.
Ott AK1,2, Locher L1,2, Koch M1,2, Deuerling E1. PLoS One. 2015 Nov 30;10(11):e0143457. doi: 10.1371/journal.pone.0143457. eCollection 2015.
Both the yeast nascent polypeptide-associated complex (NAC) and the Hsp40/70-based chaperone system RAC-Ssb are systems tethered to the ribosome to assist cotranslational processes such as folding of nascent polypeptides. While loss of NAC does not cause phenotypic changes in yeast, the simultaneous deletion of genes coding for NAC and the chaperone Ssb (nacΔssbΔ) leads to strongly aggravated defects compared to cells lacking only Ssb, including impaired growth on plates containing L-canavanine or hygromycin B, aggregation of newly synthesized proteins and a reduced translational activity due to ribosome biogenesis defects. In this study, we dissected the functional properties of the individual NAC-subunits (α-NAC, β-NAC and β'-NAC) and of different NAC heterodimers found in yeast (αβ-NAC and αβ'-NAC) by analyzing their capability to complement the pleiotropic phenotype of nacΔssbΔ cells. We show that the abundant heterodimer αβ-NAC but not its paralogue αβ'-NAC is able to suppress all phenotypic defects of nacΔssbΔ cells including global protein aggregation as well as translation and growth deficiencies.
4.[Construction of an integration vector carrying hygromycin B resistance gene and its genetic transformation in Rhizopus oryzae].
Zhang M, Jiang S, Zheng J, Zheng Z, Li X, Pan L, Luo S. Sheng Wu Gong Cheng Xue Bao. 2015 Aug;31(8):1203-18.
To construct a system of genetic transformation suitable for Rhizopus oryzae, we constructed a single-exchange vector pBS-hygro carrying hygromycin B resistance gene (hph) as its selective marker using gene splicing by overlap extension PCR (SOE PCR) technique. We introduced this recombinant vector into Rhizopus oryzae AS 3.819 by PEG/CaCl2-mediated transformation of protoplast, electroporation of protoplast and germinated spores; and we studied the effects of hydrolysis time, field strength and spore germination time on transformation frequency. We conducted quantitative real-time PCR (qPCR) assay to determine the gene copy number of ldhA integrated in the genome of R. oryzae transformants and its effect on the stability of transformants. We successfully achieved R. oryzae transformants integrated with pBS-hygro-ldhA vector. The optimal hydrolysis time for protoplast production was 140 min, and the optimal field strength of electroporation pulse for protoplast was 13 kV/cm.
