Solanum, with approximately 1,500 species, is the largest genus in the Solanaceae and includes economically important species such as the tomato, potato, and eggplant. In part due to its large size and tropical center of diversity, resolving evolutionary relationships across Solanum as a whole has been challenging. In order to identify major clades within(More)
NADP-dependent isocitrate dehydrogenase is a low-copy nuclear gene family. We have sequenced two regions from an idh gene (idhB) near the 3' terminal end. The first fragment encodes 4 exons and 3 introns and is between approximately 600 and 950 bp in length. The second fragment includes three additional exons and introns and is between approximately 1200(More)
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(More)
Members of the phlox family (Polemoniaceae) serve as useful models for studying various evolutionary and biological processes. Despite its biological importance, no family-wide phylogenetic estimate based on multiple DNA regions with complete generic sampling is available. Here, we analyze one nuclear and five chloroplast DNA sequence regions (nuclear ITS,(More)
Reverse genetic techniques harnessing mutational approaches are powerful tools that can provide substantial insight into gene function in plants. However, as compared to diploid species, reverse genetic analyses in polyploid plants such as bread wheat can present substantial challenges associated with high levels of sequence and functional similarity(More)
The endemic and rare Solanum vespertilio and S. lidii from the Canary Islands are notable in being andromonoecious, self compatible, highly heterandrous (with short >reward= anthers and one very long >pollination= anther), and bearing strongly zygomorphic corollas. Solanum vespertilio flowers are also tetramerous, and some display enantiostyly. Given their(More)
Collections of rust fungi (Pucciniales) on species of Allium in Australia have previously been identified as Puccinia allii. These identifications are unsatisfactory as P. allii is a species complex that has yet to be taxonomically resolved. Some of the cryptic species in this complex may represent new introductions and have potential biosecurity(More)
