Project description:Trichoderma harzianum T34 is a fungal strain able to promote the plant growth and to increase plant defense responses. Trichoderma harzianum transformants expressing the amdS gene, encoding an acetamidase, of Aspergillus nidulans produce a higher plant development than the wild type T34. We used microarrays to analyze the physiological and biochemical changes in tomato plants produced as consequence of interaction with Trichoderma harzianum T34 and amdS transformants
Project description:Citrus disease resistance breeding has been advanced to introduce CTV resistance of trifoliate orange to citrus. Because the quality of the fruit of trifoliate ogate was low, backcross with citrus was necessary. In the case of citrus, it takes several years from flowering to obtaining next-generation seeds. Therefore, we generated transformants for the early flowering genes (citrus FLOWERING LOCUS T: CiFT) using CiFT co-expression vector construct and promoted generation. In Japan, it is difficult to plant transformants in the field. Therefore, it was decided to select null segregant lacking transgene from backcross progenies. In order to prove that the transgene has been completely removed, it is necessary to prove that no vector conract is present on the genome. Tthis matter was proved by CGH analysis.

Project description:These experiments were performed to show serogroup conversion in Vibrio cholerae from O1 to O139 in a mixed communities / biofilms. For this purpose, V. cholerae O1 El Tor A1552 and VCO139-Kan strain (a MO10 derivative; O139 serogroup) were grown on crab shell fragments to induce natural competence for transformation. Transformants were selected on LB+Kan+Rif plates. O139 positive transformants have undergone a full exchange of the O1 region by the O139 region. This implies an exchange of an at least 32 kb spanning O1 genomic region by more than 42 kb of the O139 region. The transformation experiment was done at least five independent times; data from four experiments are shown; per experiment one to three clones were analysed by CGH with two experimental replicates each. A genotyping experiment design type classifies an individual or group of individuals on the basis of alleles, haplotypes, SNP's. Keywords: all_pairs, array CGH
Project description:We report the comparison of transcript expression in OsbZIP83 overexpression lines b83OX-13, 15 and 19 against non-transformants (NT) in Fe-sufficient roots and leaves by RNA-Seq.

Project description:Clonal variation, wherein a range of specific productivities of secreted proteins are observed from supposedly identical transformants, is an ingrained aspect of working with Pichia pastoris. It means that a significant number of transformants need to be tested to obtain a representative sample, and in commercial protein production, companies regularly screen thousands of transformants to select for the highest secretor. Here we have undertaken a detailed investigation of this phenomenon by characterising clones transformed with the human serum albumin gene. In order to evaluate the prevalence and underlying causes of clonal variation, nine strains were selected, each transformed with a single copy of the human serum albumin (HSA) gene. All strains were subjected to a wide-ranging evaluation to understand the implications of this phenomenon.
Project description:Vibrio cholerae isolate W6G transformed with DNA from VCXB21 and selected for chitosan metabolism. Nine independent transformants compared to parental W6G on microarrays containing probes for all N16961 ORFs. Regions acquired from VCXB21 hybridize more strongly to the array. A genotyping experiment design type classifies an individual or group of individuals on the basis of alleles, haplotypes, SNP's. Keywords: genotyping_design
Project description:Putative subunits of the Mg-protoporphyrin monomethylester oxidative cyclase from Synechocystis PCC 6803, sll1214 and sll1874 were expressed with N-terminal 3xFLAG-tags in separate transformants.. Solubilised thylakoid membranes from these 2 transformants were incubated with anti-FLAG agarose and after extensive washing, the FLAG-tagged proteins, together with putative interaction partners were desorbed with FLAG peptide. The eluates were denatured, reduced, alkylated and digested with trypsin. The resulting peptides were cleaned by cation exchange and desalted, then analysed by nanoLC-MS/MS. The FLAG pulldown experiment was also carried out with a thylakoid membrane preparation from wild-type with no FLAG-tagged proteins as a control. Protein identification was by database searching with Mascot.
