Fig. 4From: Evolution of group I introns in Porifera: new evidence for intron mobility and implications for DNA barcoding Cox1 (introns excluded) bayesian inference (MrBayes, GTR + G + I model) phylogeny of the Tetractinellida with focus on the family Scleritodermidae. The maximum likelihood (RAxML) tree is congruent. Squares represent node supports. Black squares: PP = 0.95–1.00, BP = 75–100. Dark gray squares: PP = 0.75–0.94, BP = 60–74. White squares: PP < 0.75, BP < 60. Numbers after each taxa are GenBank accession numbers or voucher numbers (for new sequences). Sequences generated in this study are in bold (32 sequences). Color code follows Fig. 2, except for three Scleritodermidae taxa, which possess two intron insertions (723 + 870) and marked in dark-cyan respectivelyBack to article page
