Tracing the global spread of maize (Zea mays L.) through plastome analysis of landraces.

ABSTRACT: Maize (Zea mays L.) is the most recently domesticated and dispersed worldwide among major cereals. Chloroplast genomes (plastome), with their highly conserved tetrad structure, hold a significant value in phylogenetic research due to their typical maternal inheritance. In this study, a total of 286 maize plastomes, 262 newly assembled and 24 publicly available, were investigated which included worldwide landraces, nested association mapping founders, and teosinte accessions. The maize plastomes were assembled with the filtered reads of the whole genome sequences from our re-seq data and public database by mapping to the reference plastome of B73. The maize plastomes were put into the phylogenetic analyses, with Z. perennis accession as the outgroup. The maize landraces were divided into fo
