Detection of convergent substitutions using the PCOC toolkit in the PEPC protein in sedges. Sites are ordered by their posterior probability of being convergent according to the PCOC model. Only sites with a posterior probability (pp) according to the PCOC model above a given threshold (here, 0.8) or sites detected in Besnard et al. (2009) (highlighted by a star) are represented. Sites are numbered according to Zea mays sequence (CAA33317) as in Besnard et al. (2009). Posterior probabilities for the PCOC, PC, and OC models are summarized by colors, red for pp≥0.99, orange for pp≥0.9, yellow for pp≥0.8, and gray for pp < 0.8.
