Durif producers of Durif. The grape can also be found in Israel, Brazil, Argentina, Chile, and Mexico. Confirmed as recently as 1997, old plantings of Durif continued to be used to produce popular wine in the Rutherglen, Victoria region of Australia. Durif is now grown in other wine regions of Australia, such as Riverina and Riverland, with over under cultivation by 2000. DNA fingerprinting has shown that the majority of Petite Sirah plantings in California are actually Durif. Some vineyards were found to be a field blend of Durif and other varieties, such as Mondeuse noire, all labeled as "Petite Sirah".
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
