On this end of the branch, all the leaves are strongly mosaicked and deformed (crumpled, blistered ...). <b> Watermelon mosaic virus </b> (<i> Watermelon mosaic virus </i>, WMV)
WMV5
Areas of tissue more or less wide and green in color, contiguous to the veins, give this sheet a mosaic appearance ("vein banding"). <b> Watermelon mosaic virus </b> (<i> Watermelon mosaic virus </i>, WMV)
A "vein banding", occurring locally along certain veins on this leaf, gives the blade the appearance of a patchwork mosaic. (<b><i> Watermelon mosaic virus </i></b>, WMV)
