Tobacco plants (Nicotiana tabacum cv. Xanthi-nc) inoculated with a necrotic strain of Potato virus Y (PVY, T01 isolate) developed necrotic symptoms in some systemically infected leaves, but not in younger leaves. However, PVY expressed distinct symptoms not only in the older leaves, but also in the younger leaves, of plants that had been doubly inoculated(More)
Cucumber cotyledons inoculated with Cucumber mosaic virus (CMV, Pepo strain) or Zucchini yellow mosaic virus (ZYMV, Z5-1 isolate) developed either mild chlorotic spots or no symptoms. Cotyledons treated with CMV plus ZYMV also developed mild chlorotic spots. However, plants ZYMV-inoculated cotyledons had veinal yellowing and gradual cell death by 20 days(More)
We investigated the synergistic effects of co-infection by zucchini yellow mosaic virus (ZYMV) and cucumber mosaic virus (CMV) on viral distribution in the vascular tissues of cucumber. Immunohistochemical observations indicated that ZYMV was present in both the phloem and xylem tissues. ZYMV-RNA was detected in both the xylem wash and guttation fluid of(More)
