This paper introduces a method to determine the likely progenitor species and timing of allopolyploid origins in Clarkia using read-mapping and modeling, applied to six allotetraploid species.

The paper shows that correlational selection on flower size and sugar concentration, rather than direct selection on flower color, reduces introgression at the color locus in Ipomoea cordatotriloba.

This paper reports the first reference genome assembly and annotation for Penstemon davidsonii using PacBio long-read sequencing and Hi-C scaffolding.
