Squash and cucumber plants were infected with ZYMV strains engineered to over-express enzymes involved in ethylene and gibberellin biosynthesis. Presence of the inserted ACS gene within the viral RNA was transient and the insert was deleted after 20-40 days. Ethylene over-expressing plants produced very high ethylene levels and were severely stunted. Monoecious cucumbers produced earlier, consecutive female flowers. Gibberellin over-expression was deduced from the observed phenotypic change, plants were taller and flowered earlier.
