Genome structure-based Juglandaceae phylogenies contradict alignment-based phylogenies and substitution rates vary with DNA repair genes

Abstract

The phylogenetic relationship among genera within the walnut family Juglandaceae remains unclear. Here, the authors assemble the genomes of Rhoiptelea chiliantha and Engelhardia roxburghiana, resolve the topology of this family, and propose a hybrid origin of the family from progenitors nested within or sister to Myricaceae.
