Expansion of F-box gene family in E. salsugineum. (A) Tandem duplications contribute to F-box gene family expansion. (B) The lineage-specific F-box genes in the four species. A total of 1,912 orthologous F-box genes in the four species were clustered to 428 clusters with at least two F-box genes. (C) Phylogenetic tree analysis of the total of ∼1900 F-box genes identified in the four species. The tree on the right was built based on the ∼60-aa F-box domain. Four E. salsugineum specific F-box clades were numbered by 1–4. The tree on the left was built based on the alignment of full CDS sequences of F-box genes in the four species.
