Chilean Isolate

Zucchini yellow mosaic virus (ZYMV) was described in 1981 affecting squash, melon, and other cultivated cucurbits with severe stunting and yellowing symptoms. It was reported to be present in most countries where cucurbits are grown, and in Chile since 1995, from surveys using enzyme-linked immunosorbent assay (ELISA) but without further characterization. A potyvirus was isolated from ELISA-positive symptomatic plants. The results indicate that this virus is ZYMV based on symptoms on herbaceous indicators, immunospecific electron microscopy of the purified particle, and sequencing of 395 bases of the 3′ end of the coat protein gene. The virus was detected in melon, watermelon, and squash plants. In agreement with previous descriptions for ZYMV, the Chilean isolate is a flexuous filamentous particle 740 nm long with one main protein of approximately 36 kDa. Nucleotide sequence comparisons of the 3′ portion of the coat protein gene revealed a high similarity to the Connecticut and California strains.

Plant Expression Vector

Zucchini yellow mosaic virus (ZYMV), a potyvirus, can cause major losses in cucurbit crops. With the goal of genetically engineering resistance to this disease we have engineered the ZYMV coat protein gene into a plant expression vector. The complete coat protein coding sequence, or the conserved core portion of the capsid gene, was attached to the 5' untranslated region of tobacco etch virus (TEV) in the pTL37 vector (Carrington et al., 1987, Nucl. Acid Res. 15:10066) The capsid constructs were successfully expressed by in vitro transcription and translation systems as verified by SDS-PAGE and ZYMV coat protein antibody. The constructs were then subcloned using polymerase chain reaction and attached to the CaMV 35 S transcriptional promoter on the CIBA-GEIGY pCIB710 plasmid. The constructs containing the CaMV 35S promoter, the 5' untranslated leader of TEV, and ZYMV coat protein sequences were then put between the Agrobacterium tumefaciens left and right borders in the pCIB10 vector and transferred to A. tumefaciens strain LBA4404 by triparental mating. These vectors are now being used to transform muskmelon and cucumber; resultant transgenic plants will be tested for ZYMV coat protein expression.
