摘要： Coleus blumei can be infected by several viroids of the genus Coleviroid. One year after detecting a mixed infection of coleus blumei viroid 1 (CbVd-1) and 5 (CbVd-5) in coleus seedlings inoculated with these two viroids, we found an additional viroid-like RNA. Sequence analysis revealed a viroid of 342 nucleotides that contains the central conserved region of coleviroids and is a chimera of the left half of CbVd-3 and the right half of CbVd-5. This new viroid, tentatively referred to as coleus blumei viroid 6 (CbVd-6), appears to have arisen from a natural recombination event or genome shuffling.
