Figure 7.

Nucleotide distribution around 6mA. (A) To identify key nucleotides around 6mA, the pLogo was applied to the positive data of Rosa chinensis (top), Fragaria vesca (second row), Xoc. BLS256 (third row) and Caenorhabditis elegans (bottom). The red-marked and black-mark positions indicate significantly critical positions with a Bonferroni corrected P-value < 0.01 and the positions that provide an appearance frequency of the specific nucleotide with >75%. (B) In the R. chinensis 6mA sequence, the conditional probabilities of nucleotide pairs (X and Y) were displayed. The presented nucleotide pairs more frequently appeared in the positive samples than the negative ones. The numbers and letters at the axes present the position and nucleotide, respectively.
