Fig. 4: Structural variations (SVs) of the AMGs between O. kokonorica and C. songorica.

a The maximum likelihood phylogenetic tree of the AMGs identified in O. kokonorica, C. songorica, and O. sativa. Red stars represent the 17 AMGs with higher expression (twofold change) in CLs compared with that in CHs in C. songorica. Blue stars represent the 3 AMGs with lower expression (twofold change) in CLs compared with that in CHs in C. songorica. b Examples of the four types of SVs detected in the 20 orthologous AMG pairs identified in (a). (I) SVs in upstream or downstream regions of genes; (II) SVs in gene regions (including both intron and exon); (III) Domain gain or lost; IV) gene lost. c The detailed SVs in the 20 orthologous AMG pairs between the two species. “Type” are the SV types in (b).
