Data from: Disentangling serial chloroplast captures in willows

Abstract

Chloroplast capture is a process through which the chloroplast of a focal species is replaced by the chloroplast from another species through a process of repeated backcrossing of an initial hybrid. Using whole genome sequences of nuclear and chloroplast from several species of willows (Salix spp.), we identify multiple chloroplast captures, and identify the phylogenetic relationships among these events. We present a phylogenetic strategy to discriminate among 1) a single chloroplast capture and subsequent speciation of the lineage with the captured chloroplast, 2) multiple chloroplast captures from the same parent species, and 3) serial chloroplast captures, which we define as the sequential capturing of the same chloroplast lineage across multiple species.
