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.
