  1. *With 12 species significance is indicated by P = 0.05/12 = 4.17E-03. CI = 0.95, the regression line was forced through the origin. See Materials and methods. §Adequacy of SMA regression analysis is seriously in doubt for S. cerevisiae because normal distribution of residuals is strongly violated. NA, not available.
