African spiny Solanum (subgenus Leptostemonum, Solanaceae): a thorny phylogenetic tangle
Although most diverse in the New World tropics, approximately 100 species of Solanum (Solanaceae) are native to continental Africa and Madagascar. The majority of these are ‘spiny solanums’ (subgenus Leptostemonum). We present here the first phylogenetic reconstruction of African and Madagascan species of Solanum subgenus Leptostemonum, with 62 of 76 species native to these areas, plus an addit...
متن کاملPhylogenetic Relationships in Solanum Section Androceras (Solanaceae)
The Leptostemonum clade of Solanum contains approximately 350–450 species, including the cultivated eggplant, S. melongena . This clade is characterized by the presence of prickles and apically attenuate anthers. Solanum section Androceras , the focus of this study, is a group of ca. 12 species belonging to the Leptostemonum clade. This section is unusual in the genus because of its mostly nort...
متن کاملAn explosive innovation: Phylogenetic relationships of Solanum section Gonatotrichum (Solanaceae)
Solanum is one of the largest plant genera and exhibits a wide range of morphological diversity. Solanum section Gonatotrichum, the focus of this study, is unique within the genus because of its fruits that swell with turgor pressure and explosively dehisce to disperse the seeds. We infer phylogenetic relationships within section Gonatotrichum using DNA sequence data from two nuclear regions (I...
متن کاملA 10-gene phylogeny of Solanum section Herpystichum (Solanaceae) and a comparison of phylogenetic methods.
PREMISE OF THE STUDY Solanum section Herpystichum is a lineage that comprises both widespread and very narrowly distributed species. This study investigates the phylogenetic relationships of sect. Herpystichum and evaluates several phylogenetic methods for analysis of multiple sequences. METHODS Sequence data from seven nuclear (ITS, GBSSI, and five COSII) and three plastid (psbA-trnH, trnT-t...
متن کاملUsing the tangle: a consistent construction of phylogenetic distance matrices for quartets.
Distance based algorithms are a common technique in the construction of phylogenetic trees from taxonomic sequence data. The first step in the implementation of these algorithms is the calculation of a pairwise distance matrix to give a measure of the evolutionary change between any pair of the extant taxa. A standard technique is to use the log det formula to construct pairwise distances from ...
