The selective primer HM+4 (5′-CATGAGTCCTGCTCGGTCAA [HM+TCCA]) was used in combination with each of the seven E+3 primers listed. The core sequence of EcoRI is identical to that used in the AFLP protocol by Vos et al. (1995).
Bands from four lanes were analyzed in each selective primer combination, two lanes for each parent (digested with either HpaII or MspI). Bands that were monomorphic (identical in both parents) were counted only once.
Sites showing conventional AFLP polymorphism, not related to methylation.
Bands were considered methylated if they showed polymorphism between the two isoschizomers. Bands with the same methylation pattern in both parents were scored only once.
