flowering locus t protein may act as the long-distance florigenic signal in the cucurbits.cucurbita moschata, a cucurbit species responsive to inductive short-day (sd) photoperiods, and zucchini yellow mosaic virus (zymv) were used to test whether long-distance movement of flowering locus t (ft) mrna or ft is required for floral induction. ectopic expression of ft by zymv was highly effective in mediating floral induction of long-day (ld)-treated plants. moreover, the infection zone of zymv was far removed from floral meristems, suggesting that ft transcripts do not function as the f ...200717540715
isolation and serological comparison of virus-coded proteins of three potyviruses infecting cucurbitaceous plants.cylindrical inclusion proteins (cips), amorphous inclusion proteins (aips), and virus particles were partially purified from cucurbita maxima leaves infected with zucchini yellow mosaic virus (zymv), watermelon mosaic virus 2 (wmv2), and the watermelon mosaic virus 1 strain of papaya ringspot virus (prsv-w). antisera to these individual antigens, except aips of zymv and wmv2, were prepared and used to determine with electroblot-elisa the serological differentiation indices (sdis) between homolog ...19902338401
