Fig. 4From: Characterization of Nicotiana tabacum genotypes possessing deletion mutations that affect potyvirus resistance and the production of trichome exudatesA 36,000Â bp region of scaffold Nitab4.5_0001441 including a proposed va deletion junction. Yellow and red highlighted numbers represent PCR markers used to localize one end of the va deletion region. Markers highlighted in red score positive in both wild type plants and plants with va, and are negative in TI 1406; markers shown in yellow fail to amplify a product in plants containing either va or VAM. The 637Â bp region separating markers 1441-g1 and 1441-g2 (not drawn to scale) is highlightedBack to article page
