Figure 3.
Ancestral state reconstruction of ascus dehiscence mechanism based on rRNA secondary structure signatures.
Character states were reconstructed using maximum likelihood and maximum parsimony methodsbased on a best ML structure tree. From left to right, the pie charts above internal branches resulted from the ML and MP analyses; the corresponding probabilities (MLBP, MPBP, BIPP) for the nodes were shown below internal branches. A. Schizosaccharomyces-Saccharomyces type of asci, A1 from Schizosaccharomyces octosporus (Alexopoulos et al., 1996), A2 from Saccharomyces sp. B, H. Taphrina-Neolecta type of asci; H1. naked asci of Taphrina pruni seated on host tissue, H2. exposed asci of Neolecta irregularis arising from subhymenial tissue. C, I. Orbilia-type of ascus, and apothecium of Orbilia auricolor. D, J. Operculate ascus, and apothecium of Trichophaea sp. E, K, L. Bitunicate asci, from left to right: Saccardoella sp., Myriangium bambusae (Tai, 1931), Lecanora sp., and pseudothecia of Byssosphaeria alnea and apothecium of Lecanora sp. F, M. Schizosaccharomyces-Saccharomyces type of ascus, and cleistothecia of Eupenicillium sp. G, N, O. Inoperculate asci, from left to right: Lanzia huangshanica, Sordaria sp., Erysiphe sp., and apothecium of Calycellinopsis Xishuangbanna and perithecium of Bertia macrospora var. tetraspora.

Ancestral state reconstruction of ascoma shape for 12 classes of Ascomycota based on rRNA secondary structure signatures.
Character states were reconstructed using maximum likelihood and maximum parsimony methods based on a best ML structure tree. From left to right, the pie charts above internal branches resulted from the ML and MP analyses; the corresponding probabilities (MLBP, MPBP, BIPP) for the nodes were shown below internal branches.
