Durif is a grape from southwest France, widely grown in California as Petite Sirah and is permitted in Rhone Rangers wines. In 2002, after DNA testing by ampelographers showed that Durif was a cross between Peloursin and the popular Rhône grape Syrah, Petite Sirah was officially voted in as a member of the Rhône Ranger varieties. The main white varieties are Bourboulenc, Clairette blanc, Grenache blanc, Marsanne, Muscat Blanc à Petits Grains, Picardin, Picpoul blanc,
Petite mutation petite negative mutants. Potentially, these yeasts have a different inheritance system in place for their mitchondrial genome than "S. cerevisiae" does. The frequency at which "S. castellii" spontaneously produces petites is similar to that of "S. cerevisiae", with the mitochondrial DNA of those petites being highly altered via deletion and rearrangement. Suppressive petites of "S. cerevisiae" are the most commonly observed spontaneously created mutants, whereas in "S. castellii," the most commonly observed spontaneous mutant is the neutral petite, further leading to speculation that the transference of this mutation differs between species. Petite mutation petite (ρ–) is a mutant first discovered
