Jaborosa

Jaborosa is a genus of flowering plants in the family Solanaceae, the nightshades. There are about 23 species,[1][2][3] all native to South America, where they are distributed from Peru to Patagonia. Most occur in the Andes.[3] Most can be found in Argentina[4] and ten are endemic to the country.[3]

Description

Most Jaborosa are rhizomatous perennial herbs except J. bergii and J. sativa, which are annual or biennial.[3]

Ecology

J. rotacea is pollinated by flies, and J. runcinata is pollinated by moths.[3] Sphingid moths feed on the nectar of J. integrifolia.[4]

Chemistry

Like plants in several other Solanaceae genera, many Jaborosa species contain steroid-derived compounds called withanolides.[5] Many of the withanolides isolated from Jaborosa have been dubbed jaborosalactones. Some withanolides are phytotoxic, having effects on other plants such as inhibiting germination and radicle growth.[5] Some have antifeedant effects, deterring insects such as mealworms (Tenebrio molitor),[2] the Mediterranean fruit fly (Ceratitis capitata),[1] and the African cotton leafworm (Spodoptera littoralis)[6] from consuming the plant.
