Localized hypermutation and associated gene losses in legume chloroplast genomes.
Point mutations result from errors made during DNA replication or repair, so they are usually expected to be homogeneous across all regions of a genome. However, we have found a region of chloroplastExpand

Monophyly of the Convolvulaceae and circumscription of their major lineages based on DNA sequences of multiple chloroplast loci.
Convolvulaceae, a large family of worldwide distribution, exhibit a rich diversity of morphological characteristics and ecological habitats. Previous efforts to systematize this diversity without aExpand

Genome-scale data, angiosperm relationships, and "ending incongruence": a cautionary tale in phylogenetics.
As systematists grapple with assembling the Tree of Life, recent studies have encouraged a genomic-scale approach, obtaining DNA sequence data for entire nuclear, plastid or mitochondrial genomes forExpand

Loss of all plastid ndh genes in Gnetales and conifers: extent and evolutionary significance for the seed plant phylogeny
The exact phylogenetic position of Gnetales, a small, highly modified group of gymnosperms with an accelerated rate of molecular evolution, is one of the most challenging issues for seed plantExpand

Classification of Convolvulaceae: A Phylogenetic Approach
Abstract Because recent molecular studies, based on multiple data sets from all three plant genomes, have indicated mutually congruent, well-resolved, and well-supported relationships withinExpand

Relationships Among Phaseoloid Legumes Based on Sequences from Eight Chloroplast Regions
Abstract Generic level relationships in phaseoloid legumes have received much attention using chloroplast DNA markers. However, despite this attention not all relationships are yet well-resolved.Expand

Plant genetics: Gene transfer from parasitic to host plants
Plant mitochondrial genes are transmitted horizontally across mating barriers with surprising frequency, but the mechanism of transfer is unclear. Here we describe two new cases of horizontal geneExpand

Long branch attraction, taxon sampling, and the earliest angiosperms: Amborella or monocots?
BackgroundNumerous studies, using in aggregate some 28 genes, have achieved a consensus in recognizing three groups of plants, including Amborella, as comprising the basal-most grade of all otherExpand

Horizontal acquisition of multiple mitochondrial genes from a parasitic plant followed by gene conversion with host mitochondrial genes
BackgroundHorizontal gene transfer (HGT) is relatively common in plant mitochondrial genomes but the mechanisms, extent and consequences of transfer remain largely unknown. Previous results indicateExpand

Plastid genome evolution across the genus Cuscuta (Convolvulaceae): two clades within subgenus Grammica exhibit extensive gene loss
The genus Cuscuta (Convolvulaceae, the morning glory family) is one of the most intensely studied lineages of parasitic plants. Whole plastome sequencing of four Cuscuta species has demonstratedExpand
