Watermelon (Citrullus lanatus), cantaloupe or muskmelon (Cucumis melo), squash (Cucurbita pepo), bitter gourd (Momordica charantia), and cucumber sativa) are commonly grown throughout Florida on both commercial farms home gardens, while pumpkin maxima) production is largely limited to north Florida. Anthracnose cucurbits, caused by the fungus Colletotrichum orbiculare, a common disease that occ...

At least 14 ascorbate oxidase (AO) isoenzymes with isoelectric points in the range of pH 3 /10 have been identified and their expression profile studied in various Cucurbitaceae tissues and during development and ripening of melon fruit (Cucumis melo L. var. reticulatus). At least four acidic AO isoenzymes were mainly located in the apoplastic fraction, whereas 10 basic AO isoenzymes were found...

The jasmonates are well studied in the context of plant defence but increasingly are also recognised as playing roles in development. In many systems, jasmonates antagonise the effects of cytokinins. The aim of the present work was to elucidate interactions between methyl jasmonate and cytokinin (benzyladenine) in regulating growth of zucchini (Cucurbita pepo L., cv. Cocozelle, var. Tripolis) c...

We monitored pollen-mediated transgene dissemination from commercial transgenic squash CZW-3 into its wild relative Cucurbita pepo ssp. ovifera var. texana (C. texana). Transgenic squash CZW-3 expresses the neomycin phosphotransferase II (nptII) gene and the coat protein (CP) genes of Cucumber mosaic virus (CMV), Zucchini yellow mosaic virus (ZYMV), and Watermelon mosaic virus (WMV); thereby, i...

We compared some fitness components of the wild squash species Cucurbita pepo spp. ovifera var. texana (C. texana) and three generations of hybrids (F1, BC1, and BC2) between C. texana and commercial transgenic squash CZW-3 over three consecutive years under field conditions of low (LDP) and high disease pressure (HDP) by Cucumber mosaic virus (CMV), Zucchini yellow mosaic virus (ZYMV) and Wate...
