Corallorhiza spans the early stages of a general model of plastome degradation and has added critical insight for understanding the process of plastsome evolution in heterotrophic angiosperms.
The plastid genome of the mycoheterotrophic Corallorhiza striata (Orchidaceae) is in the relatively early stages of degradation.

The Corallorhiza plastome is not drastically reduced in overall size, but displays a pattern congruent with a loss of photosynthetic function, which illustrates the urgency of their conservation.
Plastid genomes reveal support for deep phylogenetic relationships and extensive rate variation among palms and other commelinid monocots.

This study represents the most comprehensively sampled matrix of plastomes assembled for monocot angiosperms, providing genome-scale support for phylogenetic relationships of monocots, and lays the phylogenetic groundwork for comparative analyses of the drivers and correlates of such drastic differences in substitution rates across a diverse and significant clade.
Plastid phylogenomics and molecular evolution of Alismatales

Ancestral‐state reconstructions support four convergent losses of a functional NADH dehydrogenase complex in Alismatales, including a single loss in Tofieldiaceae, and investigates the molecular evolution of plastid NADH dehydration, a large enzymatic complex that may play a role in photooxidative stress responses.

Cumulative analyses of genes ranked by decreasing numbers of informative characters indicated continued fluctuation in support, even as small genes were added to a nearly complete matrix, contrary to the expected pattern of stabilization in support.
Phylogenomic analyses of species relationships in the genus Sabal (Arecaceae) using targeted sequence capture

- 2016
A sequence capture methodology was used to collect data for analyses of diversification within Sabal, a palm genus native to the south-eastern USA, Caribbean, Bermuda and Central America, validating a high-throughput methodology for generating a large number of genes for coalescence-based phylogenetic analyses in plant lineages.
Monocot plastid phylogenomics, timeline, net rates of species diversification, the power of multi-gene analyses, and a functional model for the origin of monocots.

A new functional model for the evolution of monocots and their diagnostic morphological traits from submersed aquatic ancestors is outlined, supported by convergent evolution of many of these traits in aquatic Hydatellaceae (Nymphaeales).

Findings corroborate patterns described in other fully mycoheterotrophic orchids and monotropes, represent one of the most extensive plant-fungal genetic investigations of fully my coheterotroph plants, and have conservation implications for the >400 plant species engaging in this trophic strategy worldwide.
