Fig. 8: Pair retained in one lineage but single-copy in other lineages (PROSOLs) and functional implications.

a Venn diagram showing the number of PROSOLs shared between or unique to Panicoideae, Pooideae, Bambusoideae, and Oryzoideae. b An illustration of gene retention in pair in Oryzoideae but as single-copy in representatives of three other subfamilies. The meaning of square and line colors in a syntenic block is the same as that in Fig. 7a. Gene annotations are indicated below the syntenic block. See details in Supplementary Fig. 54. c An illustration of gene retention in pair in Pooideae but as single-copy in representatives of three other subfamilies. The meaning of square and line colors in a syntenic block is the same as that in Fig. 7a. Gene annotations are listed below the synteny block. The line chart on the right of the synteny block illustrates the expression patterns of the wheat CK2β paralogs in stems collected in five-time points and different temperatures. Red, green, and blue lines represent TraesCS1A01G215700, TraesCS1B01G229200, and TraesCS4B01G379300, respectively. See details in Supplementary Fig. 55. d An illustration of gene retention in pair in Bambusoideae but as single-copy in representatives of three other subfamilies. The meaning of square and line colors in a syntenic block is the same as that in Fig. 7a. Gene annotations are listed below the synteny block. The expression patterns of two copies of SRR1 genes in Phyllostachys edulis are illustrated on the right. See details in Supplementary Fig. 56. e An illustration of gene retention in pair in Panicoideae but as single-copy in representatives of three other subfamilies. The meaning of square and line colors in a syntenic block is the same as that in Fig. 7a. Gene annotations are listed below the synteny block. The graph on the right of the synteny block illustrates the expression patterns of the sorghum PAI1 paralogues in leaves in 15 weeks in response to drought stress. Red, green, and blue curves represent control, preflowering drought, and postflowering drought, respectively. The dotted line indicates the flowering stage. See details in Supplementary Fig. 57.
