Wound-healing potato discs

FORMATION OF fi)-FERULOYLOXYPALMITIC ACID AND TETRADECYL FERULATE IN ENZYMIC EXTRACTS OF WOUND-HEALING POTATO TUBER DISCS Solanum tuberosum L.)... [Pg.456]

HHT activity was not detectable in intact potato tuber tissue but was induced upon wounding after a lag period of three days (Fig.2). The time course of induction of HHT was therefore comparable with the kinetics of accumulation of alkyl ferulates [3] and of deposition of the aliphatic components of suberin [1]. HHT activity being restricted to the outermost cell layers of the wound-healing tuber discs, the development of HHT activity was both temporally and spatially coincident with the suberization process. The... [Pg.457]
