Abstract:
Zucchini yellow mosaic virus (ZYMV) causes serious damage to cucurbit crops worldwide. In Japan, cucumbers are commonly affected by ZYMV during summer to early autumn. Infected plants exhibit severe mosaic and distortion on leaves and fruits, or wilting in grafted plants. To protect cucumber plants from ZYMV, we tried to develop an attenuated virus as the “vaccine” for preventive inoculations. We obtained a candidate vaccine, designated ZYMV-2002, following cold treatment by maintaining diseased plants at 12.5 to 15°C for about 2 months. Vaccinated cucumber plants had very similar fruit productivity to healthy control plants under field conditions. During field experiments in 2002 and 2003, vaccinated plants significantly suppressed infection with ZYMV, progression of disease severity, and reduction of fruit yield and quality. These results demonstrate that ZYMV-2002 is a potentially useful vaccine for reducing the impact of ZYMV.
