FIG. 1.

Diagrammatic representation of the mitochondrial genome of P. infestans illustrating the location of the various amplification products (shaded). Sequence locations are according to the provisional sequence supplied by B. F. Lang. The position of a ca.-1.6-kb insert present in haplotype II isolates (Cornell haplotype B) is indicated. The darker shading indicates the extent of the longer F4-R2 PCR product. Sequence positions correspond to those published by Paquin et al. (29) (available at http://megasun.bch.umontreal.ca/People/lang/species/phyti/phytmtDNA.html).
