  		Fig. 1. Image of amplification products resulting from the Pibdom primers in selected rice cultivars commonly grown in U.S. producer fields electrophoresed on a nondenaturing polyacrylamide gel. Lane identities are as follows: Lanes 1 and 20, molecular weight marker; Lanes 2 to 19, rice cultivars Bengal, BL-1, Bolivar, Cocodrie, Cypress, Francis, Gulfmont, Hildalgo, Jasmine 85, Katy, L-204, Maybelle, M-202, M-205, Saber, Te-Qing, and Wells. Note that BL-1, Bolivar, Saber, and Te-Qing are the only cultivars displaying the 365-bp amplification product found in the Pi-b gene sequence, with its position shown by an arrow to the left of the image.

  		Fig. 2. Genetic maps of marker loci on rice chromosomes 2, 11, and 12, respectively, near the (A) Pi-b gene from Te-Qing using combined data of crosses segregating for resistance to rice blast race IE-1K and presence of the Pibdom gene marker; (B) Pi-k locus conferring resistance to rice blast races IB-45, IB-54, or IG-1 using combined data of Pi-kh and Pi-ks allele segregation; and (C) Pi-ta2 gene from Katy or Kaybonnet using combined data of crosses segregating for resistance to rice blast race IB-49. Genetic distances in Morgan map units of recombination are displayed on left of each chromosome, with the centromere of chromosome 12 shown at its expected position.
