Evolutionary history of callose synthases in terrestrial plants with emphasis on proteins involved in male gametophyte development
Fig 5
Unrooted phylogenetic tree of 655 proteins sequences of the callose synthase.
The evolutionary history was inferred using maximum likelihood. Bootstrap support values ≥50% are shown on the branch above. The ML log likelihood -482640.553247. The analysis included 655 amino acid sequences and 3435 positions in the final data set. Numbers in circles indicate main clades described in the text.
