Yellow Squash and Zucchini Cultivar Evaluation in Georgia

characterization of the zucchini yellow mosaic virus from squash in tehran province

zucchini yellow mosaic virus (zymv) is a potyvirus with a worldwide distribution. this virus causes serious economic losses in iran in many cucurbits. during 2002-2003, sam-ples were collected from squash fields in tehran province. five isolates (z1, z2, z3, z4 and z5) were inoculated on 27 species of cucurbitaceae, chenopodiaceae, amarantha-ceae,solanacae, leguminosae and ranunculaceae. chenop...

Genes for resistance to zucchini yellow mosaic in tropical pumpkin.

Four cultigens of Cucurbita moschata resistant to zucchini yellow mosaic virus were crossed with the susceptible 'Waltham Butternut' and with each other in order to clarify the mode of inheritance of resistance and relationships among the genes involved. Five loci were segregating, with genes for resistance Zym-0 and Zym-4 carried by 'Nigerian Local' and one of them also carried by 'Nicklow's D...

Purification and characterization of galactinol synthase from mature zucchini squash leaves.

Galactinol synthase catalyzes the first committed step in the biosynthesis of raffinose sugars. Previous attempts to purify the enzyme have proven difficult and have resulted in low quantities of unpurified enzyme. Galactinol synthase was purified 752-fold from mature zucchini (Cucurbita pepo L. cv Burpee Hybrid) leaves using sequential liquid chromatography on DE 52, Octyl-Sepharose CL-4B, and...
