Host range and symptoms First reported
in Vanilla fragrans; from Tonga; by Pearson and Pone (1988).
Natural host range and symptoms
Symptoms persist (but
- Vanilla fragrans - chlorotic blotching or streaking and
malformed margins of tip leaves which, as they age, develop brown scab-like and
necrotic local lesions, which also form on the vines causing die-back.
Transmitted by a vector; possibly an insect;
Aphis gossypii and Myzus persicae; Aphididae. Transmitted in a
non-persistent manner. Virus transmitted by mechanical inoculation;
transmitted by grafting.
Fiji and Tonga.
Experimental host range
Several (3-9) families
susceptible. Experimentally infected plants mostly show systemic mosaics,
mottles, ringspots or necrosis and leaf malformation.
Diagnostically susceptible host species and symptoms
- Nicotiana benthamiana - systemic vein chlorosis and malformed
- Nicotiana clevelandii - mild systemic mottling.
- Chenopodium amaranticolor - necrotic local lesions; not systemic.
- C. quinoa - diffuse chlorotic local lesions; not systemic.
Maintenance and propagation hosts
Assay hosts (Local lesions or
(L), C. quinoa (L).
Susceptible host species
Insusceptible host species
Families containing susceptible hosts
Comments on host-range
Chenopodium amaranticolor, C. quinoa and Nicotiana clevelandii
only successfully infected from Nicotiana benthamiana but not directly
from Vanilla fragrans.
