Contribution of plastomes to maize domestication and improvement. A Neighbor-joining (NJ) phylogenetic tree reconstructed using SNPs of plastomes between different species of Zea using Sorghum bicolor as an outgroup. Two Z. parviglumis accessions (black arrows) were clustered in a clade with CMS cytotypes. Also indicated are representative CMS-S (B37SC), CMS-T (B37TC), and CMS-C (B37CC) (red triangles) cytotypes and fertility NA type (A188C) and NB type (B73V4C) (green triangles) cytotypes. Brach length scale = 0.05. B Genetic diversity based on SNPs of plastomes among improved lines, landraces, and Z. parviglumis. C Nucleotide diversity (π) of plastomes among improved lines, landraces, and Z. parviglumis. D Candidate regions of Cp genome under domestication (brown) and improvement (light green). Dashed line indicates the ratio value of 1. E Maize plastome of the NB cytotype (Genebank: KP966114) showing the location of photosystem I and II (indicated by triangles) gene clusters (shown on the right with colors)
