Species-wide inventory of Arabidopsis thaliana organellar variation reveals ample phenotypic variation for photosynthetic performance.

ABSTRACT: Efforts to improve photosynthetic performance are increasingly employing natural genetic variation. However, genetic variation in the organellar genomes (plasmotypes) is often disregarded due to the difficulty of studying the plasmotypes and the lack of evidence that this is a worthwhile investment. Here, we systematically phenotyped plasmotype diversity using Arabidopsis thaliana as a model species. A reanalysis of whole-genome resequencing data of 1,541 representative accessions shows that the genetic diversity among the mitochondrial genomes is eight times lower than among the chloroplast genomes. Plasmotype diversity of the accessions divides the species into two major phylogenetic clusters, within which highly divergent subclusters are distinguished. We combined plasmotypes fro
