An antiviral protein, designated Opuntin B, was purified from Prickly Pear (Opuntia ficus-indica (L.) Miller) Cladode by heat treatment of the extract, protein precipitation by ammonium sulfate treatment followed by ion-exchange chromatography. Assessment of enzymatic activity of the purified protein showed that it degrades total plant genomic RNA, while causing electrophoretic mobility shifting of Cucumber mosaic virus (CMV) RNAs.

During 2012-2015 surveys in some orchards in Faraghe (Iran), a number of apricot trees showed symptoms resembling those associated with the phytoplasma disease known as European stone fruit yellows that are severe leaf roll, yellowing and die back. The presence of an infectious agent was confirmed by graft transmission experiments in which all the previously symptomless GF-677 (peach × almond) trees showed phytoplasma-type symptoms. The phytoplasma presence was confirmed by nested PCR assays using DNA extracted from samples from both field collected and graft-inoculated trees.

Melon seedlings showing systemic chlorotic spots and mosaic symptoms were collected in central part of Iran, and a virus was isolated from diseased plants by mechanical inoculation. The virus systemically infected the most inoculated test plants by inducing mosaic symptoms, while, in the members of Fabaceae family and Chenopodium quinoa induced local lesions. Agar gel diffusion test using a polyclonal antiserum against a squash Cucumber mosaic virus (CMV) isolate showed the presence of CMV in the mechanically inoculated plants (designated CMV-Me).
