Fig. 4: GDs mapped at Arundinarieae and Bambuseae and their relationship to kappa.

a Number of GDs mapped at Arundinarieae. See Supplementary Fig. 39 for the number of GDs (and GDs anchored in genome collinear blocks) shared by different species in Arundinarieae. The meaning of numbers in square brackets and round parentheses is as in Fig. 3 and, also shown below. Capital A, the MRCA of Arundinariinae and Hsuehochloinae subtribes; capital B, Ampelocalaminae subtribe. b Illustration of an intraspecific collinear block of Phyllostachys edulis. Lines between different chromosome fragments represent collinear genes, some of which are linked by thick and colored lines indicating different phylogenetic positions of the duplication shared by the genes as shown below the blocks. The meaning of red and blue rectangles is the same as that in Fig. 2b. c Number of GDs mapped at Bambuseae. See Supplementary Fig. 40 for the number of GDs (and GDs anchored in genome collinear blocks) shared by different species in Bambuseae. The meaning of numbers in square brackets and round parentheses is as in Fig. 3 and, also shown below. Capital A, the palaeotropical Bambuseae; capital B, the neotropical Bambuseae. d Illustration of an intraspecific collinear block of Dendrocalamus latiflorus. The meaning of lines between different chromosomal fragments is the same as that in part b. The meaning of red and blue rectangles is the same as that in Fig. 2b.
