From: Nationwide genomic surveillance reveals the prevalence and evolution of honeybee viruses in China
Analysis of small RNAs and variants of Apis picorna-like virus 4. A Size distributions (15 to 37 nt) and 5’-nucleotide compositions of small RNAs arising from APLV4. B Mapping of 20- to 23-nt-long viral RNAs to the genome of APLV4. C Observed 5’ nucleotide (Obs) compared with that expected (Exp) from the base compositions of the viral genomes for APLV4. Sense (S, high-expressed strand) and antisense (AS, low-expressed strand) reads were compared by using a chi-squared test. **p <0.01; ***p < 0.001. D Percentage of positive libraries for APLV4 within different host species. E Phylogenetic tree of APLV4 complete genomes identified in honeybees collected from different regions of China from different years. F Chinese provinces in which APLV4 was detected. Eastern and western honeybees are colored in red and blue, respectively
