Figure 2.

Amplification results obtained with 16 Phytophthora species (Table 1) using primers designed against P. sojae, P. ramorum and P. infestans genomes using Approach 1 (Fig. 1A). NA represents primer-species combinations in which amplification reactions did not produce any product or produced complex profiles (two or more PCR fragments) preventing direct sequencing. NS represents primer-species combinations in which amplification reactions produced single PCR bands, however direct sequencing did not yield reliable sequences. SQ represents primer-species combinations in which reliable sequences were obtained.
