The Leguminosae has emerged as a model for studying angiosperm plastome evolution because of its striking diversity of structural rearrangements and sequence variation. However, most of what is known about legume plastomes comes from few genera representing a subset of lineages in subfamily Papilionoideae. We investigate plastome evolution in subfamily...

Acids contribute important flavor characteristics to
many foods and beverages. They occur naturally in these
products, arise from fermentation processes, or can be
added. Most acids taste sour. However, little is known
about their time-intensity characteristics of sourness.
This project was set forth to see if selected acids could be...
Despite knowledge that concerted evolution of high-copy loci is often imperfect,
studies that investigate the extent of intragenomic polymorphisms and comparisons
across a large number of species are rarely made. We present a bioinformatic pipeline
for characterizing polymorphisms within an individual among copies of a high-copy
locus. Results are presented...

Horizontal gene transfer (HGT) of DNA from the plastid to the nuclear and mitochondrial genomes of higher plants is a common
phenomenon; however, plastid genomes (plastomes) are highly conserved and have generally been regarded as impervious to HGT.
We sequenced the 158 kb plastome and the 690 kb mitochondrial genome...

This dataset contains a draft assembly of the common milkweed (Asclepias syriaca) nuclear genome, linkage group information, and gene family counts for Asclepias and related species. The genome assembly is accompanied by annotation of gene models, repeat models, transfer RNAs, and open reading frames, and mapping information of Asclepias transcripts,...
PREMISE OF THE STUDY: Hyb-Seq, the combination of target enrichment and genome skimming
allows simultaneous data collection for low-copy nuclear genes and high-copy genomic targets
for plant systematics and evolution studies.
METHODS AND RESULTS: Genome and transcriptome assemblies for milkweed (Asclepias syriaca)
were utilized to design enrichment probes for 3385...
Phylogenetics benefits from using a large number of putatively independent nuclear loci and their combination with other sources of information, such as the plastid and mitochondrial genomes. To facilitate the selection of orthologous low‐copy nuclear (LCN) loci for phylogenetics in nonmodel organisms, we created an automated and interactive script to...
The taste qualities of acidulants have not been studied in detail despite
the fact that they are widely used by the food industry. Studies on
characterizing the sensory properties of organic and inorganic acids are very
limited. Reported studies are commonly on threshold, equi-sour and the time
intensity values of...
Glacial isostatic adjustment (GIA) alters the amplitude and timing of ‘glacioeustatic’ sea level maxima and minima around the globe. No study has examined the intrinsic distance that one can correlate marine stratigraphic records of glacial–interglacial sedimentation across continental shelves subject to varying amounts of GIA. Here, we seek to model...
