For more details: Wu et al. 2018, "Genomics of the origin and evolution of Citrus" https://www.nature.com/articles/nature25447 https://www.nature.com/articles/nature25447 > "To investigate the genetic diversity and evolutionary history of citrus, we analysed the genomes of 58 citrus accessions and two outgroup genera (Poncirus and Severinia) that were sequenced to high coverage, including recently published sequences as well as 30 new genome sequences described here... We identified ten progenitor citrus species by combining diversity analysis, multidimensional scaling and chloroplast genome phylogeny."
