In the great majority of species, the flowers have a differentiated perianth with a calyx and corolla (with five sepals and five petals, respectively) an androecium with five stamens and two carpels forming a gynoecium with a superior ovary[7] (they are therefore referred to as pentamers and tetracyclic). In Solanaceae, floral zygomorphy is observed in androecium, corolla, and/or calyx. To humans, these alkaloids can be desirable, toxic, or both. The androecium has (2)(4)5(6) free stamens within it, oppositsepals (that is, they alternate with the petals), they are usually fertile or, in some cases (for example in Salpiglossideae) they have staminodes. 2. It is widely distributed all over the world in tropical, subtropical and temperate zones. Mostly plants contain 2n = 24 (2 x 12) chromosomes but polyploidy is also seen with chromosomes in multiples of 12. Medicinal Chemistry and Drug Design. One of the aspects of the solanaceas’ genomics is an international project that is trying to understand how the same collection of genes and proteins can give rise to a group of organisms that are so morphologically and ecologically different. Centers of diversity also occur in Australia and Africa.
