  • a Host strains as described in Table 3. A, presence of homoallelic genes in host; +, a compatible interaction; +w, a weak compatible interaction; −, an incompatible interaction. Where both genes of the pair gave a compatible interaction, this is scored as +; when only one of the pair gave a compatible interaction, the interactions for both genes are given individually as −/ + , +/ −, +/ +w, or +w/ + as appropriate.
