Host-specific gene expression in Arthrobotrys oligospora . Scatter plot of normalized mapped reads of A. oligospora and H. schachtii (Ao(Hs)) versus A. oligospora and M. hapla (Ao(Mh)). Genes that were regulated (≥1 read) in both libraries and that had ≥5 reads in any of the libraries were included in the analysis, 4 138 genes in total. The Pearson correlation coefficient (r) of the comparison is also shown. The diagonal line (y = x) shows transcripts with near identical expression levels. The dotted lines correspond to a five-fold expression difference.
