Durif of the officially sanctioned grapes of the Côtes du Rhône AOC, Petite Sirah's linking to Durif caused the California's Rhone Rangers to add the grape to its listings of wine in 2002. In Israel, Petite Sirah had a history much like that in California—historically used as a blending grape to add body to inferior wines. However, Petite Sirah has recently experienced somewhat of a revival, both in high-end blends and bottled as a single or majority variety. The UC Davis-trained winemaker and Ph.D. chemist Ya'ir Margalit, familiar with the grape from his time in California, showed that Petite Sirah need
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
