Caulimoviridae: A family of DNA plant viruses with isometric or bacilliform virions and no envelope. The host ranges of most species are narrow. There are six genera: CAULIMOVIRUS; BADNAVIRUS; Cavemovirus; Soymovirus; Petuvirus; and TUNGROVIRUS.Cestrum: A plant genus of the family SOLANACEAE. Members contain steroidal saponins and cause CALCINOSIS in grazing livestock due to high levels of 1 ALPHA,25-DIHYDROXYVITAMIN D3.Badnavirus: A genus of DNA plant viruses with bacilliform morphology. Transmission in clonally-propagated plants is by vegetative propagation of infected plant materials. Transmission in nature is by mealybugs, seeds, and pollen. The type species is Commelina yellow mottle virus.
