Project description:Mycoplasma gallisepticum is a convenient model object for studying the regulation of transcription because it has a reduced genome, lack of cell wall and many metabolic pathways, and also easy to culture and non-pathogenic to humans. For rapid investigation of gene expression we developed microarray design including 3 366 probes for 678 genes. They included 665 protein coding sequences and 13 antisense RNAs from 816 genes and 17 ncRNAs present in Mycoplasma gallisepticum. This work was carried out transcriptomic profiling for different types of effects on the expression of genes of Mycoplasma gallisepticum: 1) genetic knock-out mutants; 2) cell culture exposed to sublethal concentrations of antibiotics; and 3) well-characterized heat stress effect. The study was performed on Agilent one-color microarray with custom design and random-T7 polymerase primer for cDNA synthesis. Using set of different probes for each gene or ncRNA allows to increase accuracy of gene expression quality.
