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.
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.

A genus of the family BROMOVIRIDAE which infects mainly woody plants. Species are divided into ten subgroups. Tobacco streak virus is the type species.
A family of RNA plant viruses with a wide host range in crops and horticultural species. All viruses are readily transmitted by mechanical means and some by insects and pollen. The genera include: ALFAMOVIRUS; BROMOVIRUS; CUCUMOVIRUS; ILARVIRUS; and OLEAVIRUS.
The type species of genus Mastrevirus, family GEMINIVIRIDAE.
