A cytochemical and biochemical study of Agrobacterium rhizogenes ‐transformed (hairy) roots of Valerianella discoidea has demonstrated: (a) the presence of a soluble valepotriate fraction in root sections in addition to the stored valepotriates in lipid droplets; (b) that roots need to be at least 3.5 cm long before they will synthesise/store valepotriates; (c) that there is a loss of valepotriates from the pericycle cells about to form lateral roots; and (d) an accumulation of seven times more monoene and diene valepotriates compared with non‐transformed, control roots.
