EVOLUTION. For the article “Adaptive evolution in the Arabidopsis MADS-box gene family inferred from its complete resolved phylogeny,” by León Patricio Martínez-Castilla and Elena R. Alvarez-Buylla, which appeared in issue 23, November 11, 2003, of Proc. Natl. Acad. Sci. USA (100, 13407–13412; first published November 3, 2003; 10.1073/pnas.1835864100), due to a printer's error in the footnote of Table 1, “*, P < 0.05” incorrectly appeared as “*, P < 0.5.” The corrected table appears below.
Table 1. Sites under PDS in the A. thaliana MADS-box gene family: “Site-specific analyses”.

Each comparison has n sequences, dN/dS is average ratio over sites under a codon model with one ω. Proportion of the component of positively selected sites (P1) and parameters p and q of the beta distribution β(p,q) are given under M8. *, P < 0.05; **, P < 0.005; ***, P < 0.001; bold underlined, PP ≥ 0.99 of being under positive selection; bold, 0.99 > PP ≥ 0.95; italics, 0.95 > PP ≥ 0.90; underlined, 0.90 > PP ≥ 0.70; normal, 0.70 > PP ≥ 0.50.
