SDS-PAGE of soluble proteins (27 μg/lane) from 6-, 18-, and 30-month-old tubers during sprouting. Note the loss of the 85-kD PMC (black arrow) and 40-kD patatin (white arrow) with advancing tuber age. PMC was present in 6-month-old tubers and nondetectable in 18- and 30-month-old tubers, as confirmed by western analysis with anti-PMC (see Fig. 4B, inset). Aging also effected an increase in glutathione reductase (58 kD, black arrowhead) as well as the loss of several other unidentified proteins (e.g. 20 kD, white arrowhead).
