Figure 2.
Diagram of the portion of mitochondrial Cytochrome Oxidase I (COI) gene used to identify strain and the individual corn-strain (CS) haplotypes. The putative translational start site of the COI gene was arbitrarily designated as coordinate 0. Short block arrows indicate location and direction of the COI-893F and COI-1303R primers used for PCR amplification and DNA sequencing. Vertical lines within the COI gene identify polymorphic sites with the rice-strain (RS) specific EcoRV site identified. All polymorphic sites except 1287 were used to identify or confirm strain identity. The CS-h haplotypes were determined by the polymorphisms at site 1164 and 1287.
