The assembly is haploid, and the genome is paleotetraploid. It has a haploid genome size of 2200 Mb, and has 10 haploid chromosomes.

Species herbarium records

Herbarium records of Zea mays ssp. mays B73v5 from AuBuchon-Elder et al 2022 are plotted with black points, The sampled individual this genome was generated from is shown in a colored point. The green background shows the biogeographic ranges of all Andropogoneae species in AuBuchon-Elder et al 2022.

Dotplot of Zea mays ssp. mays B73v5 vs. Paspalum vaginatum

Like dotplots shown in Figure 3 of the main text, this shows syntenic blocks in Zea mays ssp. mays B73v5 along the y-axis, vs P. vaginatum on the x-axis. As Zea mays ssp. mays B73v5 is a paleotetraploid with a haploid assembly, we expect 2 paths for any x-axis position.

Fractionation of Zea mays ssp. mays B73v5

Like plots shown in Figure 4 of the main text, this shows proportion of retained genes in Zea mays ssp. mays B73v5 along the y-axis, vs P. vaginatum gene index on the x-axis. As Zea mays ssp. mays B73v5 is a paleotetraploid with a haploid assembly, we expect 2 lines, one for each subgenome.
