Phylogenetic position and plastid genome structure of , a mycoheterotrophic genus of Orchidaceae (subtribe Orchidinae) endemic to Vietnam.

The orchid genus comprises three species, all discovered in the 21 century. Each of these species is achlorophyllous, mycoheterotrophic and is known to be endemic to Vietnam. The type species of the genus, , occurs in a single location in northern Vietnam within a lowland limestone karstic area.

The Group (Fabaceae): Can Phylogenetic Patterns Be Accommodated by a Taxonomic Concept?

The group represents an example of obvious contradictions between the molecular and morphological data. This group includes from six to eight mostly annual species of section , with the center of species diversity in the Mediterranean. We performed a phylogenetic analysis of the genus with an expanded representation of all known species of the group using both nuclear (nrITS) and a set of plastid DNA markers and compared the results with traditional taxonomy of this group.

When Morphology and Biogeography Approximate Nuclear ITS but Conflict with Plastid Phylogeny: Phylogeography of the Species Complex (Leguminosae).

s.l. is a complex of taxa traditionally regarded as members of .

Two centuries from species discovery to diagnostic characters: molecular and morphological evidence for narrower species limits in the widespread SW Australian complex (Restionaceae s.l./Anarthriaceae, Poales).

Background: The extreme southwest of Australia is a biodiversity hotspot region that has a Mediterranean-type climate and numerous endemic plant and animal species, many of which remain to be properly delimited. We refine species limits in , a Western Australian endemic genus characterised by the occurrence of the greatest number of plesiomorphic character states in the restiid clade of Poales. In contrast to many other groups of wind-pollinated Australian Poales, was traditionally viewed as having well-established species limits.

Phylogenetic Placement and Phylogeography of Large-Flowered Species (Leguminosae) Formerly Classified in : Evidence of Pre-Pleistocene Differentiation of Western and Eastern Intraspecific Groups.

The Mediterranean region is a center of species and genetic diversity of many plant groups, which served as a source of recolonization of temperate regions of Eurasia in Holocene. We investigate the evolutionary history of species currently classified in sect. in the context of the evolution of the genus as a whole, using phylogenetic, phylogeographic and dating analyses.

Gradual vs. abrupt reduction of carpels in syncarpous gynoecia: A case study from Polyscias subg. Arthrophyllum (Araliaceae: Apiales).

Premise Of The Study: Revealing the relative roles of gradual and abrupt transformations of morphological characters is an important topic of evolutionary biology. Gynoecia apparently consisting of one carpel have evolved from pluricarpellate syncarpous gynoecia in several angiosperm clades. The process of reduction can involve intermediate stages, with one fertile and one or more sterile carpels (pseudomonomery).

Complete Plastid Genome of the Recent Holoparasite Lathraea squamaria Reveals Earliest Stages of Plastome Reduction in Orobanchaceae.

Plants from the family Orobanchaceae are widely used as a model to study different aspects of parasitic lifestyle including host-parasite interactions and physiological and genomic adaptations. Among the latter, the most prominent are those that occurred due to the loss of photosynthesis; they include the reduction of the photosynthesis-related gene set in both nuclear and plastid genomes. In Orobanchaceae, the transition to non-photosynthetic lifestyle occurred several times independently, but only one lineage has been in the focus of evolutionary studies.

Pollination of Vietnamese Aspidistra xuansonensis (Asparagaceae) by female Cecidomyiidi flies: larvae of pollinator feed on fertile pollen in anthers of anthetic bisexual flowers.

Unlabelled: •

Premise Of The Study: Aspidistra is a species-rich, herbaceous monocot genus of tropical Southeast Asia. Most species are recently discovered and apparently endangered, though virtually nothing is known about their biology. Species of the genus are primarily distinguished using flower morphology, which is enormously diverse.

Phylogenetics of Anthyllis (Leguminosae: Papilionoideae: Loteae): Partial incongruence between nuclear and plastid markers, a long branch problem and implications for morphological evolution.

Phylogenetic relationships in the genus Anthyllis (Leguminosae: Papilionoideae: Loteae) were investigated using data from the nuclear ribosomal internal transcribed spacer regions (ITS) and three plastid regions (psbA-trnH intergenic spacer, petB-petD region and rps16 intron). Bayesian and maximum parsimony (MP) analysis of a concatenated plastid dataset recovered well-resolved trees that are topologically similar, with many clades supported by unique indels. MP and Bayesian analyses of the ITS sequence data recovered trees that have several well-supported topological differences, both among analyses, and to trees inferred from the plastid data.

Comparative chloroplast genomics and phylogenetics of Fagopyrum esculentum ssp. ancestrale -a wild ancestor of cultivated buckwheat.

Background: Chloroplast genome sequences are extremely informative about species-interrelationships owing to its non-meiotic and often uniparental inheritance over generations. The subject of our study, Fagopyrum esculentum, is a member of the family Polygonaceae belonging to the order Caryophyllales. An uncertainty remains regarding the affinity of Caryophyllales and the asterids that could be due to undersampling of the taxa.

Complete sequence of the duckweed (Lemna minor) chloroplast genome: structural organization and phylogenetic relationships to other angiosperms.

The complete nucleotide sequence of the duckweed (Lemna minor) chloroplast genome (cpDNA) was determined. The cpDNA is a circular molecule of 165,955 bp containing a pair of 31,223-bp inverted repeat regions (IRs), which are separated by small and large single-copy regions of 89,906 and 13,603 bp, respectively. The entire gene pool and relative positions of 112 genes (78 protein-encoding genes, 30 tRNA genes, and 4 rRNA genes) are almost identical to those of Amborella trichopoda cpDNA; the minor difference is the absence of infA and ycf15 genes in the duckweed cpDNA.
