Characterization of a potexvirus isolated from night blooming cactus hylocereus undatus

, : Characterization of a potexvirus isolated from night blooming cactus hylocereus undatus. Plant Disease 67(4): 438-440

Plants of night-blooming cactus H. undatus as well as scions of several species of cactus grafted to it were stunted, malformed and systemically mottled. A flexuous virus averaging 515 nm long was isolated from the affected plants. The virus was sap-transmitted to a limited number of hosts. Symptoms in Chenopodium guinoa consisted of chlorotic primary lesions and systemic mottle and necrosis. Gomphrena globosa and Amaranthus caudatus showed primary local lesions. Plants of Saponaria vaccaria showed only systemic mottling. Crystalline inclusions were found by light microscopy in epidermal cells of infected H. undatus. The virus had a thermal inactivation point above C and a dilution end point of 106-107 in sap from infected C. quinoa. The virus reacted with antisera prepared against California barrel cactus and Chessin's isolate of cactus virus X.

The leading hypothesis on the ancestor of domestic goats (Capra hircus) is that it is the wild goat called the bezoar or pasang (Capra aegagrus). To verify this hypothesis, we sequenced and compared the cytochrome b gene of mitochondrial DNA from...
