Transcription profiling data set of different states of Mycoplasma gallisepticum

Mycoplasma gallisepticum belongs to class Mollicutes and causes chronic respiratory disease in birds. It has a reduced genome, lack of cell wall and many metabolic pathways, and also easy to culture and non-pathogenic to humans. Aforementioned made it is a convenient model for studying of systems biology of minimal cell. Studying the transcriptomic level of M. gallisepticum is interesting for both understanding of common principles of transcription regulation of minimal cell and response to definite influence for pathogen bacteria. For rapid investigation of gene expression we developed microarray design including 3366 probes for 678 genes. They included 665 protein coding sequences and 13 antisense RNAs from 816 genes and 17 ncRNAs present in Mycoplasma gallisepticum. The study was performed on Agilent one-color microarray with custom design and random-T7 polymerase primer for cDNA synthesis. Here we present the data for transcription profiling of M. gallisepticum under different types of exposures: genetic knock-out mutants, cell culture exposed to sublethal concentrations of antibiotics and well-characterized heat stress effect. Mutants have transposon insertion to hypothetical membrane protein, lactate dehydrogenase, helicase with unknown function, 1-deoxy-d-xylulose 5-phosphate reductoisomerase or potential sigma factor. For inhibition of important cell systems, treatment with carbonyl cyanide m-chlorophenylhydrazone (CCCP), novobiocin or tetracycline were chosen. Data are available via NCBI Gene Expression Omnibus (GEO) with the accession number GSE85777 (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE85777).
