Fig. 1: Characterization of the allotetraploid O. kokonorica genome.

a Morphology of O. kokonorica. 1: Plants in native habitat. 2: Chromosome counts (2n = 40) in an O. kokonorica cell. 3: Plant with leaves, roots and rhizomes. 4: Underground root system. 5: Plant grown in greenhouse. b Collinearity within the O. kokonorica genome. Tracks from inside to the outside correspond to (1) gene synteny between chromosomes; (2) gene density; (3) LTR/Gypsy retrotransposons; (4) LTR/Copia retrotransposons; (5) ncRNA density; (6) GC content; (7) Pseudochromosomes of O. kokonorica. c Dotplots showing the Ks values of homologous genes between the Oko (O. kokonorica) and Cso (C. songorica) genomes. d Gene synteny between the Oko, Cso, and Otho (O. thomaeum) genomes.
