Recruitment of CRABS CLAW to promote nectary development within the eudicot clade
TLDR
It is proposed that diverse nectaries in core eudicot species share conserved CRC gene regulation, and that derived nectary positions in eudicots have altered regulation of CRC. Expand
Phylogeny of extant and fossil Juglandaceae inferred from the integration of molecular and morphological data sets.
TLDR
The results clearly show that the amount of missing data in any given taxon is not by itself an operational guideline for excluding fossils from analysis, and each of the methods provided reasonable placement of both fossils and simulated "artificial fossils" in the phylogeny previously inferred only from extant taxa.

Phylogeny and Systematics of Prunus (Rosaceae) as Determined by Sequence Analysis of ITS and the Chloroplast trnL-trnF Spacer DNA
TLDR
The objective of this study was to reconstruct the phylogeny of Prunus with the purpose of reviewing previously described taxonomic relationships and providing a basis for studies of morphological evolution in the genus. Expand
The evolution of Dactylorhiza (Orchidaceae) allotetraploid complex: insights from nrDNA sequences and cpDNA PCR-RFLP data.
TLDR
A maximum likelihood tree based on combined ETS and ITS sequences suggests that the Western European Dactylorhiza allotetraploids have evolved by hybridization between four main diploid lineages and four species are recognized, namely D. majalis, D. praetermissa,D. Expand
Phylogenetic utility of the second intron of LEAFY in Neillia and Stephanandra (Rosaceae) and implications for the origin of Stephanandra.
TLDR
Comparison of the LEAFY data with ITS and cpDNA data demonstrated that the LEafY intron was the most variable and useful for phylogenetic analysis at the species level, providing many more phylogenetically informative characters per 100 bp than either ITS or cpDNA. Expand
Phylogenetic Relationships and Taxonomic Status Of the Paleoendemic Fagaceae Of Western North America: Recognition Of A New Genus, Notholithocarpus
TLDR
Results indicate that Notholithocarpus does not possess true ‘flower cupules,’ which define Lithocarpu sensu stricto, but like the oaks, the single flower per cupule is derived through the abortion of lateral flowers within each cupule. Expand
Phylogeny and Historical Biogeography of the Genus Platanus as Inferred From Nuclear and Chloroplast DNA
TLDR
Phylogenetic analyses of DNA sequences of six species of Platanus were conducted to estimate species relationships and analyze biogeographic history, and the root node for the genus was confirmed to fall between subg. Expand
Molecular phylogenetics and cupule evolution in Fagaceae as inferred from nuclear CRABS CLAW sequences
TLDR
This work used CRABS CLAW, a single-copy nuclear gene, to generate over 2,900 base pairs of new sequence data, and combined it with previously collected molecular data to examine morphological evolution in the Fagaceae, and proposed a new hypothesis to explain the evolution of the unusual cupules of Asian Lithocarpus and Chrysolepis. Expand
Nuclear ribosomal DNA sequence variation and evolution of spotted marsh-orchids (Dactylorhiza maculata group).
TLDR
It is shown that in some instances two lineages, contributed to the observed intra-individual polymorphism, and evolutionary scenarios leading to this extensive nuclear ribosomal DNA polymorphism are discussed in the light of results from maternally inherited chloroplast DNA markers and an autopolyploid origin of D. maculata. Expand
The complete chloroplast genome sequence of Viburnum erosum (Adoxaceae)
TLDR
Phylogenetic analyses show that V. erosum is sister to Viburnum japonicum, supporting morphological affinity of the two species. Expand
