Structure of the G3pdh region in Manihot. Numbers 1–4 indicate the positions of primers: GPDX7F (1), GPD9R2 (2), GPD9R4 (3), and GPDX9R (4). Uppercase and lowercase letters designate exons and introns, respectively, as follows: partial exon A (52 bp), intron a (84 bp), exon B (98 bp), intron b (265 bp), exon C (143 bp), intron c (101 bp), exon D (84 bp), intron d (101 bp), and partial exon E (34 bp). The cross-hatched region within intron b indicates a variable minisatellite.
