Number of sequence reads and mean read coverage of viral genomes from mined transcriptome data sets.

Sequence coverage was determined in Geneious software version 9.1.7 with BBMap using de novo assemblies generated by VirFind [9]. Abbreviations: J2 (second-stage juvenile), SCN (soybean cyst nematode), BCN (beet cyst nematode), CCN (cereal cyst nematode), PCN (potato cyst nematode), Gp (Globodera pallida), Gr (G. rostochiensis), NLV (nyami-like virus), BLV (bunya-like virus), PLV (picorna-like virus). Mean describes average sequence read coverage for each nucleotide position. ND (not detected) denotes the virus was not found in the specified nematode sample.
