physiological function | CYP79D1 and CYP79D2 are the two paralogous genes encoding the first committed enzymes in linamarin and lotaustralin synthesis. Blocking expression by RNA interference results in lines with acyanogenic leaves. Only a few of these lines are depleted with respect to cyanogenic glucoside content in tubers. Cyanogenic glucosides are synthesized in the shoot apex and transported to the root, resulting in a negative concentration gradient basipetal in the plant with the concentration of cyanogenic glucosides being highest in the shoot apex and the petiole of the first unfolded leaf | Manihot esculenta |
