Coleviroid - Coleus blumei viroids (CbVd)

The viroid genus Coleviroid contains several Coleus blumei viroids that infect the ornamental plant Coleus blumei and are widely distributed. These include, for example, Coleus blumei viroid 1 (CbVd-1) first described from Brazil, or CbVd-2, CbVd-3 and CbVd-4, all three originally described from Germany. Various leaf symptoms have been described and these appear to depend on the cultivar. They include irregular chlorotic spots and patches, albino symptoms as well as symptomless infections.

stable structures for viroids from the genus Coleviroid. The secondary structure of 3 Coleviroids, CbVd-1, CbVd-2 and CbVd-3, is shown. The nucleotides in black denote those of low SHAPE reactivities (0–0.40). Those in orange are of intermediate reactivities (0.40–0.85) and those in red are highly reactive (>0.85). The central conserved regions (CCR) are delimited by the vertical bars. The arrows indicate additional identical sequences. (click on image to enlarge it)
