Towards a new classification of the Arthoniales (Ascomycota) based on a three-gene phylogeny focussing on the genus Opegrapha.
TLDR
The simultaneous use of a mitochondrial gene and two nuclear genes led to the detection of what seems to be a case of introgression of a mitochondrion from one species to another (mitochondrion capture; cytoplasmic gene flow) resulting from hybridization. Expand
The phylogenetic utility of chloroplast and nuclear DNA markers and the phylogeny of the Rubiaceae tribe Spermacoceae.
TLDR
IT was, despite often raised cautions of its utility at higher taxonomic levels, shown to provide the highest number of parsimony informative characters, and in partitioned Bayesian analyses it yielded the fewest trees in the 95% credible set. Expand
CARNOY: A new digital measurement tool for palynology
TLDR
CARNOY is an image analysis application written from the ground up for use in palynology and morphology that can export measurements to almost every other software package for further analysis and is available for free on the Internet. Expand
Distribution and Evolution of Circular Miniproteins in Flowering Plants[W]
TLDR
It is predicted that the number of cyclotide within the Rubiaceae may exceed tens of thousands, potentially making cyclotides one of the largest protein families in the plant kingdom. Expand
Phylogeny of the Herbaceous Tribe Spermacoceae (Rubiaceae) Based on Plastid DNA Data1
TLDR
This study is the first to address phylogenetic relationships within Spermacoceae from a tribal perspective and provides a phylogenetic hypothesis with broad sampling across the major lineages of Spermcoceae that can be used to guide future species-level and generic studies. Expand
Palynological characters and their phylogenetic signal in Rubiaceae
TLDR
The systematic usefulness of pollen morphology in Rubiaceae is discussed at the (sub)family, tribal, generic, and infraspecific levels, using up-to-date evolutionary hypotheses for the different lineages in the family. Expand
Exploring the floristic diversity of tropical Africa
TLDR
RAINBIO – one of the largest mega-databases of tropical African vascular plant species distributions ever compiled – is used to address questions about plant and growth form diversity across tropical Africa, and is important for achieving Objective 1 of the Global Strategy for Plant Conservation 2011–2020. Expand
The Hedyotis-Oldenlandia complex (Rubiaceae: Spermacoceae) in Asia and the Pacific : Phylogeny revisited with new generic delimitations
TLDR
The present study focuses on Asian-Pacific taxa from these groups and aims at resolving taxonomic inconsistencies by describing monophyletic genera within the Hedyotis-Oldenlandia complex. Expand
Endophytic Bacteria in Toxic South African Plants: Identification, Phylogeny and Possible Involvement in Gousiekte
TLDR
The discovery and identification of Burkholderia bacteria in gousiekte-inducing plants open new perspectives and opportunities for research not only into the cause of this economically important disease, but also into the evolution and functional significance of bacterial endosymbiosis in Rubiaceae. Expand
Cyclotide discovery in Gentianales revisited--identification and characterization of cyclic cystine-knot peptides and their phylogenetic distribution in Rubiaceae plants.
TLDR
These findings confirm cyclotides to be one of the largest peptide families within the plant kingdom and suggest that their total number may exceed tens of thousands. Expand
