Oil palm genetic orange spotting
Oil palm orange spotting viroid, and its abbreviation is OOSVd. A viroid is a length of RNA, much smaller than the RNA of the smallest virus, and without a protein coat. OOSVd is closely related to a viroid in the Philippines, Coconut cadang-cadang viroid (CCCVd), which causes a lethal disease in coconuts and other palms.
