Analyses of 202 plastid genomes elucidate the phylogeny of Solanum section Petota

Abstract : Our paper analyzes full plastid DNA sequence data of 202 wild and cultivated diploid potatoes, Solanum section Petota, to explore its phylogenetic utility compared to prior analyses of the same accessions using genome-wide nuclear SNPs, and plastid DNA restriction site data. The present plastid analysis discovered the same major clades as the nuclear data but with some substantial differences in topology within the clades. The considerably larger plastid and nuclear data sets add phylogenetic resolution within the prior plastid DNA restriction site data, highlight plastid/nuclear incongruence that supports hypotheses of hybridization/introgression to help explain the taxonomic difficulty in the section.
