Extended Data Fig. 1. Genome assembly and annotation.
a–c, Genome contiguity (a) and library coverage (b) demonstrate that the v5 release is a very complete genome and that it is among the best available plant reference genomes (c), compared to maize128 durum wheat129, broomcorn millet130, teff131, poplar132, soybean70, cotton47, walnut133 and strawberry46. d, Complete collinearity between marker order in both crosses (number of markers = 4,701) of a 4-way mapping population is evident. e, Genome annotation statistics present a gene annotation that is as complete as the assembly. f, Observed heterozygosity ranges from <4 to >10% among our 732-library resequencing panel. g, Nearly the entire single-copy genome of P. hallii is syntenic with both switchgrass subgenomes; pale blue polygons represent syntenic blocks between subgenomes and P. hallii. The one exception is a previously known over-retained region representing the ρ duplication on Chr. 03 and 0864.
