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:These experiment were performed to show a serogroup conversion in Vibrio cholerae from O1 to O139. For this purpose, V. cholerae O1 WT = A1552 was grown on crab shell fragments to induce natural competence for transformation. Purified DNA (2 ug each) from strain VCO139-Kan was added after 24h and the cells grwon further for 24h. The VCO139-Kan strain is a MO10 derivative (both O139 serogroup) which harbors a Kanamycin cassette in the O139 region (as part of the operon between wbfA and wbfB w/o own promotor) for better selection. Transformants were selected on LB+Kan plates. Two groups of transformants were gained: Group I had a full exchange of the O1 region by the O139 region (clones serogroup-converted: SGC#1-3); the crossovers for the homologous recombination event had occurred within or upstream of the gmhD gene and in most instances within or downstream of the homolog gene of VC0271. This implies an exchange of an at least 33 kb spanning O1 genomic region by more than 42 kb of the O139 region. Group II had only half of the O139 region transfered and therefore half of the O1 region kept (clones HSGC#4-6). We analyzed their genotype and found that all of them had undergone a homologous recombination event with one crossover in or upstream of the gmhD gene and the second one inside the VC0254 and IS1358 gene. The transformation experiment was done three independent times (I - III). Three clones from group I and group II were selected from each experiment and analyzed by microarray hybridization (BioPrime. Array CGH Genomic Labeling from Invitrogen). Two microarray replicates were done per clone. A genotyping experiment design type classifies an individual or group of individuals on the basis of alleles, haplotypes, SNP's. Strain Name: -III for experimental replicates (transformation); clones #1 -#3 full region exchanged; clones #4-#6 half region exchanged.

Project description:Transcriptome of starchy endosperm of hexaploid wheat var. Cadenza at 5 stages during grain-fill. This provides a reference set of all genes which are expressed in this single cell type during development which is of huge importance for human nutrition and for industrial uses of wheat grain. Here we focus on genes in glycosyl transferase and glycosyl hydrolase families which are responsible for the non-starch polysaccharide composition of wheat flour.

Project description:These experiments were performed to show a serogroup conversion in Vibrio cholerae from O1 to O139. For this purpose, V. cholerae O1 WT = A1552 was grown on crab shell fragments to induce natural competence for transformation. Purified DNA (2 ug each) from strain VC73-orf6/7-Kan-A was added after 24h and the cells grown further for 24h. The VC73-orf6/7-Kan-A strain is a ATCC25873 derivative (both O37 serogroup) which harbors a Kanamycin cassette in the O37 region (as part of the operon between orf6 and orf7 w/o own promotor) for better selection. Transformants were selected on LB+Kan plates. Three clones were selected from each experiment and analyzed by microarray hybridization (BioPrime. Array CGH Genomic Labeling from Invitrogen). Two microarray replicates were done per clone. Comparison of A1552 versus VC73-orf6/7-Kan-A is shown as control.

Project description:These experiments were performed to show a serogroup conversion of Vibrio cholerae from O1 to 37. For this purpose, V. cholerae O1 El Tor (A1552) was grown on crab shell fragments to induce natural competence for transformation. Purified DNA (4 ug each) from strain ATCC25872, an O37 serogroup strain, was added after 24h and the cells were further grown for 24h. After detachment from the crab shell fragments, bacteria were poured into soft-agar and overlaid onto LB plates. Mukerjee's El Tor phage III (a gift of Dr. M.S. Islam) was dropped onto the surface of the bacteria containing soft-agar. The plaques formed by killing non-transformed A1552 cells possessed resistant clones which were picked and further selected by non-agglutination with O1-specific antiserum. One to four clones were selected from each independent experiment and analyzed by microarray hybridization (BioPrime. Array CGH Genomic Labeling from Invitrogen). Two microarray replicates were done per clone. Strain Names: AIpO37#1 / AIpO37#4 / AIpO37#6 / AIpO37#8 are clones analyzed from the first experiment; AIIpO37#9 / AIIpO37#13 / AIIpO37#16 are clones analyzed from the second independent experiment; AIIIpO37#9A is a clone analyzed from the third independent experiment; AIVpO37#1A / AIVpO37#3A / AIVpO37#4A / AIVpO37#8A are clones analyzed from the fourth independent experiment. Two MA replicates per clone were done. CGHs of A1552 versus ATCC25872 are provided as control.
