A, FITC-casein hydrolyzing proteinase activity of extracts from 6- (○), 18- (•), and 30-month-old (▵) tubers. B, Inhibition of the proteinase activity in extracts from 18- (•) and 30-month-old (▵) tubers with extracts from 6-month-old tubers. Data are averages ± se of three replicates (se values are eclipsed by the symbols in B). Inset shows immunoblots of PMC (32 μg of protein per lane) in extracts from tubers, before and after the addition of 6-month-old extract to extracts from 18- and 30-month-old tubers.
