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 and exhibit Mendelian 1:1 segregation. Neutral petites (rho–N): Neutral petite when crossed to wild-type, all offspring are wild-type. It has inherited normal mitochondrial DNA from wild-type parent, which is replicated in the offspring. Suppressive petites (rho–S): crosses between petite and wild-type, all offspring are petite, showing "dominant" behavior to suppress wild-type mitochondrial function. Most petite mutants of "S. cerevisiae" are of a suppressive type, and they differ from neutral petite by affecting the wild-type, although both are a mutation in mitochondrial DNA. Mitochondrial genome of yeast will be the first eukaryotic genome to be understood in terms of both structure
