Reassessing Banana Phylogeny and Organelle Inheritance Modes Using Genome Skimming Data.

ABSTRACT: Bananas (Musa spp.) are some of the most important fruit crops in the world, contributing up to US$10 billion in export values annually. In this study, we use high-throughput sequencing to obtain genomic resources of high-copy DNA molecules in bananas. We sampled 13 wild species and eight cultivars that represent the three genera (Ensete, Musa, and Musella) of the banana family (Musaceae). Their plastomic, 45S rDNA, and mitochondrial scaffolds were recovered from genome skimming data. Two major clades (Clades I & II) within Musa are strongly supported by the three genomic compartment data. We document, for the first time, that the plastomes of Musaceae have expanded inverted repeats (IR) after they diverged from their two close relatives, Heliconiaceae (the lobs
