Synonyms
Zygocactus spp.
Family: Cactaceae Ornamental
Cactus virus X (CVX)
Taxonomic position
Genus: Potexvirus Family: Alphaflexiviridae
CVX infection in plants of Schlumbergera spp. was reported from Germany, and Brazil (Casper and Brandes 1969; Giri and Chessin 1972; Koenig et al. 2004; Duarte et al. 2008). The virus-infected thanksgiving cactus plants do not exhibit any apparent symptoms and therefore generally remain undetected (symptomless). In some cases the infected plants show chlorotic spotting and reddening of the fronds (Chessin 2002). The virus is mechanically sap-transmissible and Chenopodium amaranticolor showed erratic systemic symptoms following inoculations from Schlumbergera truncata (Duarte et al. 2008). For more details of CVX, refer to Opuntia spp.

Genus: Potexvirus Family: Alphaflexiviridae
OpVX was reported from Brazil in plants of Schlumbergera truncata showing mottling or chlorotic spotting (Duarte et al. 2008). The...
