Karyological studies in Jaborosa (Solanaceae)
Sixteen species of Jaborosa (Solanaceae), including eight endemic to Argentina, were studied karyologically. The numbers n = 12 and/or 2n = 24 were found in all species, the majority of the cases being new reports. Mitotic chromosomes were smallto medium-sized, the average length varying from 2.95 to 4.93 mm. All species had one to three chromosome pairs with satellites. The karyotypes, obtaine...
متن کاملThe Systematics of Solanum Section Allophyllum (Solanaceae)
Three species of Solanum are included in a new section, Solanum sect. Allophyllum. Two of the species, S. allophyllum and S. mapiriense, have been previously known; the third, S. morellifolium Bohs, is described as new. The combination of characters exhibited by members of this section, such as unbranched hairs, 2-3-leaved sympodial units, simple leaves with decurrent bases, and tapered anthers...
متن کاملAnther wall formation in Solanaceae species.
Anther wall formation was studied in 32 species belonging to 27 genera of Solanaceae. Dicotyledonous and basic types of wall formation were observed, as well as several deviations due to subsequent periclinal divisions in the layers formed (middle layers and sometimes the endothecium). One type of wall formation was observed in each species. Some genera are uniform in their type of wall formati...
متن کاملChemodiversity of surface flavonoids in Solanaceae.
Several species of Nicotiana and Solanum and further members of the Solanaceae have been examined for their exudate flavonoids. Most of the aglycones are widespread flavonols, but rare and unusual flavonols were also found, e.g. in exudates of Physalis and Solanum species. Flavones occur throughout the family, but flavanones are rare. Our data are presented in comparison to previous results. Th...
متن کاملEvolutionary Relationships in Tribe Lycieae (Solanaceae)
We examine evolutionary relationships among the three genera in tribe Lycieae using DNA sequence data from the nuclear granule-bound starch synthase gene (GBSSI, waxy). Tribe Lycieae is comprised of the large cosmopolitan genus Lycium and the predominately South American genera Grabowskia and Phrodus. Phylogenetic results strongly suggest that Lycium contains Grabowskia and may also include Phr...
