Dinucleotide bias for the Mycosphaerella graminicola repeat families identified by RECON. A specific dinucleotide bias (CpA ↔ TpA) was detected in the repeat families comprising Class I and Class II transposable elements. Ten families of MITEs and 14 of unclassified repeats showed no specific dinucleotide bias. The different dinculeotide biases that were evaluated are color coded: red, CpA ↔ TpA; blue, CpC ↔ TpC; green, CpG ↔ TpG; cyan, CpT ↔ TpT. RIP dominance, in a given alignment, is the ratio of a particular CpN↔TpN to the sum of the three other CpN↔TpN mutations. The arrows are shown bidirectionally to indicate that changes on both strands of DNA are analyzed (e.g., a C → T mutation on one strand will be seen as G → A on the complementary strand).
