Albino tea cultivars have precious white shoots or yellow shoots and are widely cultivated in China to produce high quality green tea with fresh taste and high aroma, including temperature-sensitive albino mutants and light-sensitive albino mutants. Physiological and biochemical indicators showed that the levels of pigments, total catechins and caffeine decreased, the content of total amino acids, especially theanine increased, and the chloroplast structure were abnormal in albino leaves; molecular studies displayed that expression of genes encoding chloroplast structure and chlorophyll synthesis, such as light harvesting chlorophyll a/b-binding protein, glutamyl-tRNA reductase, Mg-chelatase H subunit, S-adenosylmethionine synthetase and glutamine synthetase, suppressed in albino period
