“…Plant anatomical features and cellular structures typically associated with the biosynthesis and storage of large amounts of terpenoids are well studied and include glandular trichomes (Gershenzon et al, 2000;Iijima et al, 2004;Siebert, 2004;Schilmiller et al, 2008;Xie et al, 2008;Chatzopoulou et al, 2010;Lane et al, 2010), laticifer cells (Mahlberg, 1993;Post et al, 2012), resin cells, resin blisters, or resin ducts (Martin et al, 2002;Zulak and Bohlmann, 2010), and glandular cavities lined by epithelial cells (Heskes et al, 2012;Voo et al, 2012). Here, we showed accumulation of the partly lipophilic diterpenoid forskolin and the presence of its precursor, (13R) manoyl oxide, together with a series of other labdane-and abietane-type diterpenoids, in root cork cells of C. forskohlii.…”
