Transcription profiling by array of Ralsonia eutropha H16 wild type and glucose-utilizing mutant G+1 cultivated in medium with fructose or glucose
ABSTRACT: In order to identify genes which contribute on the uptake of glucose into cells of the mutant R. eutropha G+1, a genome wide transcription analyses was done. Transcripts of strain H16 and the glucose-utilizing mutant R. eutropha G+1, cultivated in mineral salts medium supplemented with either fructose or glucose were compared.
By taking advantage of the available genome sequence of Ralstonia eutropha H16, glucose uptake in the UV-generated glucose-utilizing mutant R. eutropha G(+)1 was investigated by transcriptomic and proteomic analyses. Data revealed clear evidence that glucose is transported by a usually N-acetylglucosamine-specific phosphotransferase system (PTS)-type transport system, which in this mutant is probably overexpressed due to a derepression of the encoding nag operon by an identified insertion mutati ...[more]

Project description:PDR mutants , strain YYA100 (pdr1?::KanMx6, pdr3?::His3Mx6) from Mol Biol Cell. 2007 December; 18(12): 49324944, was grown to OD 1-1.5 in YEPD and hybridyzed to an expression array in one channel with a wild-type strain reference RNA on the other channel
Project description:We performed a gene expression analysis of C. albicans SC5314 planktonic cells exposed to the antifungal peptide ApoEdpL-W. Exponentially-growing C. albicans SC5314 cells in SD at 30°C medium were exposed to 2.5 µM ApoEdpL-W and samples were collected after 10 and 30 min. for transcript profiling
