Genes with recurrent mutations identified in both haploids and diploids, or whose mutation has been previously shown to be adaptive.

Mutations in bolded genes are specifically “nitrogen adaptive” (see below). Ty1 and Ty2 were the only retrotransposons responsible for novel adaptive insertions, and nearly all new insertions are Ty1. For additional details on specific Ty1/2 insertions such as location, family and orientation, see S2 and S4 Files.
