In many instances, bee viruses are found as non-apparent infections in their host. This may result from competition between the viral RNA and the abundant DI-like RNAs, but also from the abundance of double-stranded RNA structures carrying viral sequences.  

RNA recombination may elicit protein divergence with obvious evolutionary impact. Furthermore, a reciprocal exchange between host DNA and viral RNA (or a DNA version of a recombinant viral RNA) has been demonstrated. 

Therefore, RNA recombination may engender divergence in host genes, and the evolution of both virus and host may be interrelated and linked to the very same eliciting process.  -- Maori, Sela, et al
