cDNA AFLP analysis of TDFL431 expression during the tuber life cycle. The expression profile during the 10 d of the in vitro tuberization system (A) and in the 12 time points of dormancy template (B). The numbers indicate days in A and weeks in B; *, 1 week after sprouting; #, 3 weeks after sprouting. C, The expression in 12 different plant tissues: young leaves (Ly), old leaves (Lo), petioles (P), stem nodes (N), stem internodes (IN), roots (R), young stolons (Sy), swelling stolons (Sw), young tubers (Ty), dormant tubers (To), tubers after sprouting (Tas), and sprouts (Sp). The black dotted line indicates the band corresponding to the TDFL31.
