Popis: | The 12 species of Solanum sect. Micracantha are part of the large subgenus Leptostemonum or “spiny solanums,” which includes some 350–400 species. Members of the section are found in the Neotropics and are characterized by a combination of characters including a viny, climbing habit using recurved prickles, unbranched inflorescences, deeply divided corollas, and glabrous fruits. Broad-scale phylogenetic relationships within the spiny solanums have been the subject of several recent studies, but many of the individual groups, including sect. Micracantha, have received little attention. In this study we infer relationships within sect. Micracantha and its placement within the spiny solanums using DNA sequence data from three chloroplast markers, trnT-F, rpl32-trnL, and ndhF-rpl32 and five nuclear markers, ITS, waxy, and three COSII markers: At1g44760 (COS4b), At1g50020 (COS5c), and At2g15890 (COS5). Results support the monophyly of sect. Micracantha (the Micracantha clade) and its sister relationsh... |
