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.
Phylogeny of extant and fossil Juglandaceae inferred from the integration of molecular and morphological data sets.
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
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.

Phylogeny and Historical Biogeography of the Genus Platanus as Inferred From Nuclear and Chloroplast DNA
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.
Phylogenetic Relationships and Taxonomic Status Of the Paleoendemic Fagaceae Of Western North America: Recognition Of A New Genus, Notholithocarpus
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.

Phylogenetic reconstruction of Prunus as determined by analysis of the combined data set suggests an early split into two clades, as a result of very short branches that may indicate rapid radiation.

Molecular phylogenetics and cupule evolution in Fagaceae as inferred from nuclear CRABS CLAW sequences
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.
