Less pollen-mediated gene flow for more signatures of glacial lineages: congruent evidence from balsam fir cpDNA and mtDNA for multiple refugia in eastern and central North America.

PLoS ONE, 2015
The phylogeographic structure and postglacial history of balsam fir (Abies balsamea), a transcontinental North American boreal conifer, was inferred using mitochondrial DNA (mtDNA) and chloroplast DNA (cpDNA) markers.

The Evolution and Origin of Allotetraploid Aegilops geniculata Revealed by the Homoeolog‐Resolved Genome Assembly

Plant Biotechnology Journal, EarlyView.
ABSTRACT Aegilops geniculata Roth is a tetraploid (MgMgUgUg; 2n = 4x = 28) wild relative of wheat and a valuable source of genetic diversity for improving agronomic traits. We present a high‐quality homoeolog‐resolved assembly and annotation of the Ae.
