Figures & Tables

Figure 1:

Reverse transcription-polymerase chain reaction (RT-PCR) detection of the root lesion nematode virus (RLNV1) from cDNA libraries generated from 21 out of the 31 populations of Pratylenchus penetrans collected in North America. PCR amplification was performed using specific primers for the RLNV1 helicase (A) and RdRP (B) regions. The isolate NL 10p RH was used as positive control for the detection of the RNLV1. C: The nematode 18 S rRNA gene was used as a positive control to validate the presence of P. penetrans transcripts within each generated cDNA library.
