Modern chromosome derivation in orchardgrass and four other grass species. (a) Modern chromosome derivation in orchardgrass, O. sativa, B. distachyon, H. vulgare and A. tauschii from ancestral chromosomes. AGKindicates the ancestral grass karyotype. (b) Proportion of monocot‐specific genes (relative to dicot genes) to all genes on each chromosome in the five grass species. The conserved chromosomes chr1 and chr5 in O. sativa, chr2 in B. distachyon, chr4 in orchardgrass, chr3 in H. vulgare and chr3 in A. tauschii had higher monocot‐specific gene proportions than other chromosomes. (c) Circos plot of regions of orchardgrass syntenic to O. sativa, B. distachyon, orchardgrass, H. vulgare and A. tauschii.
