Infectious clone-rescued small-plaque ZIKV and unique M protein mutation. a Plaque phenotype on Vero cells and mutations of infectious clone-derived ZIKV, based on sequences of small-plaque variants (white arrow) purified from C6/36-derived PF13 stock. b The amino acid sequences of various ZIKV strains of different lineages (Asian and African) and both wild-type and vaccine strains, if available, of various mosquito-borne flaviviruses were aligned and the unique M66V mutation in DN-2 is highlighted in red and indicated with an arrow
