Figure 5: Active conservation of non-coding regions.
From: Sequencing of Aspergillus nidulans and comparative analysis with A. fumigatus and A. oryzae
a, Example region between a conserved pair of orthologous histone H2A and H2B genes (left and right blue arrows). The three lines from top to bottom correspond to the sequences of A. nidulans, A. fumigatus and A. oryzae aligned using Mlagan. Letters on the red background indicate 100% conserved bases. b, Conservation scores of maximal subsequences for observed intergenic alignments (red), and models of neutral and random sequence alignment (both fixed and variable length).
