"Signal intensities were averaged among the technical replicates. Two types of data analysis were performed: to indentify density-dependent changes in gene expression, single averaged normalized signal intensities for each treatment point were compared to the average of corresponding unstressed control signal intensities. Genes which showed a relative signal log2ratio (SLR) value above 1.0 or below -1.0 were selected for further analysis. "	"data_processing.1"
