Zucchini yellow mosaic virus (ZYMV)

<b> Cucumber mosaic virus </b> (<i> Cucumber mosaic virus </i>, CMV) and <b> zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV), melon
Twigs bearing several very deformed, blistered and serrated leaves. </b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
Pale green leaves dotted with small darker green islands, sometimes angular. <b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
Regular and generalized embossing over the entire blade, on a melon leaf. </b> Virus complex </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV; <i> Cucumber mosaic virus </i>, CMV and <i> Watermelon mosaic </i> 2 < i> virus </i>, WMV-2)
Blisters whose dark green coloring contrasts with the lighter one of the rest of the leaf blade, giving the melon leaf a mosaic appearance. <b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
Very serrated leaf on which is also observed a large blister. </b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV).
Leaf very indented and covered with very pronounced blisters. </b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV).
Partially blistered and deformed leaf also exhibiting an enation. </b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
The very short internodes indicate a blockage in the growth of this melon plant. </b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
Growth arrest and yellowing of the leaves of the melon apex. <b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
Superficial brown necrosis called "in marker stroke" (= streak) on petiole and on melon apex. <b> Zucchini yellow mosaic virus </i>, ZYMV) </b>
Apex of a melon plant wilting and then necrosis; sometimes a superficial brown necrosis develops on part of the stem and petioles. <b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
Melon fruits affected by <b> zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV), in addition to being mosaicked, are also more or less dented and distorted.
Blistered melon leaves with jagged edges, slightly mosaic fruit. <b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
Ring spots on green fruit. <b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
Large white spots, slightly raised on green fruit. <b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
Transverse and longitudinal corky cracks covering a melon fruit. <b> Zucchini yellow mosaic virus </b> (<i> Zucchini yellow mosaic virus </i>, ZYMV)
