New investigation results, 'Caffeine biosynthesis and degradation in tea [Camellia sinensis (L.) O. Kuntze] is under developmental and seasonal regulation,' are detailed in a study published in Molecular Biotechnology. According to a study from Palampur, India, "To study caffeine biosynthesis and degradation, here we monitored caffeine synthase gene expression and caffeine and allantoin content in various tissues of four Camellia sinensis (L.) O. Kuntze cultivars during non-dormant (ND) and dormant (D) growth phases." "Caffeine synthase expression as well as caffeine content was found to be higher in commercially utilized tissues like apical bud, 1st leaf, 2nd leaf, young stem, and was lower in old leaf during ND compared to D growth phase. Among fruit parts, fruit coats have higher caffeine synthase expression, caffeine content, and allantoin content. On contrary, allantoin content was found lower in the commercially utilized tissues and higher in old leaf," wrote P. Mohanpuria and colleagues, Council of Scientific and Industrial Research. The researchers concluded: "Results suggested that caffeine synthesis and degradation in tea appears to be under developmental and seasonal regulation." Mohanpuria and colleagues published their study in Molecular Biotechnology (Caffeine biosynthesis and degradation in tea [Camellia sinensis (L.) O. Kuntze] is under developmental and seasonal regulation. Molecular Biotechnology, 2009;43(2):104-11). For more information, contact P.
