Fig. 4: Origin of a fern insecticidal protein.
From: Fern genomes elucidate land plant evolution and cyanobacterial symbioses
Phylogenetic analysis of the chitin-binding domain Pfam PF03067 shows that the fern Tma12 insecticidal protein was probably derived from bacteria through an ancient HGT event. The numbers above the branches are bootstrap (BS) support values (BS = 100 is omitted), and the thickened branches indicate BS > 70. The tree is rooted based on the result from a broader phylogenetic analysis of PF03067 and PF08329 (Supplementary Data). The pink star denotes the sequence from the S. cucullata genome.
