Fig 1.
Example of multiple hybridizations at the origin of a type strain. Current S. bayanus strains, including CBS380T, are segregants of tetrads issued from a cross of S. uvarum with another strain (NBRC1948 or similar), itself a hybrid issued from a cross of S. uvarum with another genome, presently designated S. lagerae (see the text). This hybrid shows traces of introgression from an S. cerevisiae wine strain. (Reprinted from reference 152, which was published under a Creative Commons license.)
