Table 1 The HeatMap of the 8 pathogenesis-related (PR) proteins screened from microarray meta-analysis in response to different stresses in potato plants. Expression values in each cell are log2-transformed ratios of different stresses/control samples. Red color indicated up- and blue down regulated genes, and white no significant change
