Gamay Blanc Gloriod Gamay Blanc Gloriod Gamay Blanc Gloriod is an obscure French variety of white wine grape. Very little of it is grown commercially. It is named after Émile Gloriod, who discovered it as a seedling; it was originally thought to be a white version of the Gamay grape. "Gamay Blanc" was already used as an alternative name for Chardonnay, which is another white grape that looks like Gamay. The gardener Émile Gloriod, from Gy in Haute-Saône, discovered Gamay Blanc Gloriod in 1895. At first it was thought to be a seedling of Gamay, and conventional ampelography linked it to the Melon
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.
