Chromosomal locations and gene duplication events of Euphorbiaceae SBP genes. For cassava, the sequence number represents the chromosome number. For physic, rubber tree and castor bean, the scaffold numbers are indicated on the top and their detail scaffold IDs are recorded in Additional file 1: Table S3. SBP gene pairs from segmental duplications are linked by blue lines; tandem duplications are marked by black circle. Each species are plotted in a unique part of (a) rubber tree, (b) cassava, (c) physic nut, (d) castor bean
