Hemagglutinin H5 hydrophilicity mutation matrix. Note the localization of the most prominent mutations in the second and fourth quadrants, indicating the predominance of mutations that tend to preserve hydrophilicity. These prominent mutations correspond to well-known conservative mutation pairs like Ile and Val and Lys and Arg; other prominent mutations are indicated in the figure.
