Figure 2: Scatter plot comparisons of the transcriptome of strain SN2 in four environmental test conditions, TF-N, TF-P, SW-N, and SW-P.

The r figures indicate correlation coefficients between the RPKM values (read number per kb of each coding sequence, per million mapped sequences) of two representative test conditions. TF, tidal flat; SW, seawater; P, pyruvate; N, naphthalene.
