Systematics And Floral Evolution In The Plant Genus Garcinia (Clusiaceae), Patrick Wayne Sweeney
Systematics And Floral Evolution In The Plant Genus Garcinia (Clusiaceae), Patrick Wayne Sweeney
Dissertations
The pantropical genus Garcinia (Clusiaceae), a group comprised of more than 250 species of dioecious, trees and shrubs, is a common component of lowland tropical forests and is best known by the highly prized fruit of mangosteen (G. mangostana). The genus exhibits as extreme diversity of floral form as is found anywhere in angiosperms and there are many unresolved taxonomic issues surrounding the genus. To understand patterns of floral evolution within the group and to evaluate morphology-based classification schemes involving Garcinia and its relatives, relationships among a broad sample of Garcinia and close relatives were inferred by conducting Bayesian, parsimony, …
Oligonucleotide Primers For The Detection Of Bioluminescent Dinoflagellates Reveal Novel Luciferase Sequences And Information On The Molecular Evolution Of This Gene, Andrea Baker, Ian Robbins, Mark A. Moline, Maria Debora Iglesias-Rodriguez
Oligonucleotide Primers For The Detection Of Bioluminescent Dinoflagellates Reveal Novel Luciferase Sequences And Information On The Molecular Evolution Of This Gene, Andrea Baker, Ian Robbins, Mark A. Moline, Maria Debora Iglesias-Rodriguez
Biological Sciences
Bioluminescence is reported in members of 18 dinoflagellate genera. Species of dinoflagellates are known to have different bioluminescent signatures, making it difficult to assess the presence of particular species in the water column using optical tools, particularly when bioluminescent populations are in nonbloom conditions. A "universal" oligonucleotide primer set, along with species and genus-specific primers specific to the luciferase gene were developed for the detection of bioluminescent dinoflagellates. These primers amplified luciferase sequences from bioluminescent dinoflagellate cultures and from environmental samples containing bioluminescent dinoflagellate populations. Novel luciferase sequences were obtained for strains of Alexandrium cf. catenella (Whedon et Kof.) Balech …
Phylogenetic Utility Of Ycf1 In Orchids: A Plastid Gene More Variable Than Matk, Kurt M. Neubig, W. Mark Whitten, Barbara S. Carlsward, Mario A. Blanco, Lorena Endara, Norris H. Williams, Michael Moore
Phylogenetic Utility Of Ycf1 In Orchids: A Plastid Gene More Variable Than Matk, Kurt M. Neubig, W. Mark Whitten, Barbara S. Carlsward, Mario A. Blanco, Lorena Endara, Norris H. Williams, Michael Moore
Barbara S. Carlsward
Plastid DNA sequences have been widely used by systematists for reconstructing plant phylogenies. The utility of any DNA region for phylogenetic analysis is determined by ease of amplification and sequencing, confidence of assessment in phylogenetic character alignment, and by variability across broad taxon sampling. Often, a compromise must be made between using relatively highly conserved coding regions or highly variable introns and intergenic spacers. Analyses of a combination of these types of DNA regions yield phylogenetic structure at various levels of a tree (i.e., along the spine and at the tips of the branches). Here, we demonstrate the phylogenetic utility …
