Figure 5. Confirmation of the presence of BPV2, BPV3, BPV4 and BuGV1 sequences in snail RNA samples.

Figure 5

A band of the expected size (339 bp; BPV2 short) for BPV2 was detected on examination of RT-PCR products from 19 of the 21 BP snail samples, but not from BuG (samples 22-24). Longer fragments of BPV2 (BPV2 long), BPV3, BPV4 were detected in some BP samples, but not in BuG samples. BuGV1 was amplified only from BuG samples (See Fig. S1 for uncropped gel images). Lane numbers correspond to sample numbers in Table 1. M, DNA size markers.
