<p style="text-align: justify;"><b>Expressed Material</b></p>

<p style="text-align: justify;">The levels of expression of ZYMV and WMV2 coat proteins were quantitated by enzyme linked immunosorbent assay (ELISA) and found to range between 73 &ndash; 1218 ng/g fresh weight and 47-112 ng/g fresh weight, respectively. These concentrations were significantly lower those measured in naturally virus infected samples of zucchini squash, yellow crookneck squash, cantaloupe and honeydew melons obtained from supermarket shelves. These latter levels have been estimated to be up to 268 and 421 fold greater than the corresponding amounts of ZYMV and WMV2 CP produced in transgenic squash.</p>
