The 89 genes with undetected expression in NAUH117 (M) compared to that in Wangshuibai (W) before and after the infection by Fg . Each line refers to data of one gene. Each row refers to a cluster of genes for each library. The color bar on the right represents the log2 of TPM values for each gene, ranging from gray (-3.3) to Purple red (8). Lighter color indicates greater transcript accumulation from bottom to top. The log2 of the undetected value, designated as 0.1 TPM, was -3.3 which the color was represented at the bottom end of color bar. 1: 61 unigenes can be detected in all 3 libraries of Wangshuibai that cannot be detected in NAUH117 in all of the 3 corresponding libraries; 2: One unigene, which can be detected in W24 and W48 libraries rather than W0 library of Wangshuibai, cannot be detected in all 3 libraries of NAUH117; 3: 19 unigenes can be detected in all 3 libraries of Wangshuibai but cannot be detected in at least two libraries of NAUH117; 4: 8 unigenes, which were detected to have no more than 1.23 TPM in all three libraries of NAUH117, can be detected in all 3 libraries of Wangshuibai and exhibited a significantly higher gene expression level compared to that in NAUH117. The arrows indicated 12 unigenes which were up-regulated in Wangshuibai in response to the infection by Fg.
