Coalescent trees based on different datasets. ASTRAL support values (local posterior probability, LPP) of each node are marked. The values from low to high corresponds to the gradient color from red to blue. E1, E2, T1, T2, alt, acu, and eic are shorthands for specific clades. h, sc, T1, T2, t1, and t2 are shorthands for specific clades. The phylogenetic relationships different from that of original tree (2594 OGs, BS > 10) are marked with red dotted lines. a1–a5 Phylogenetic relationships reconstructed from 2594 gene trees with five different threshold bootstrap values ranging from 10 to 50. b Phylogenetic relationships reconstructed by 1594 OGs with relatively low copy number. c Phylogenetic relationship reconstructed by 1000 OGs with relatively high copy number (no topology change)
