Gamay Beaujolais Gamay Beaujolais Gamay Beaujolais is a varietal designation for a Californian grape variety, an early ripening clone of Pinot noir. In the late 1930s, an early pioneer of the American viticulture, Paul Masson, brought with him several Burgundian grapes for his winery in California. One of those grapes he believed to be the Gamay variety from the Beaujolais region in France, which in the 1940s University of California at Davis (UCD) researchers christened "Gamay Beaujolais". In the late 1960s, UCD scientists decided that Gamay Beaujolais was a clonal selection of Pinot noir, and that California's version of the true Gamay
Petite mutation be induced using a variety of mutagens, including DNA intercalating agents, as well as chemicals that can interfere with DNA synthesis in growing cells. Mutagens that create Petites are implicated in increased rates of degenerative diseases and in the aging process. A mutation that produces small (petite" > petite) anaerobic-like colonies had shown first in Yeast Saccharomyces cerevisiae and described by Boris Ephrussi and his co-workers in 1949 in Gif-sur-Yvette, France. The cells of petite colonies were smaller than those of wild-type colonies, but the term “petite” refers only to colony size and not the individual cell size. Over 50
