Estimation of divergence rates between markers for <i>Symbiodinium</i> types C1, C15, C90, and C91.

The minimum, maximum and averaged uncorrected genetic distances among clade C Symbiodinium types are indicated for each marker investigated. Calculations for calmodulin, rad24, and actin were made on sequence alignments excluding (−) and including (+) introns. aNo sequences were obtained for Symbiodinium C90 and C91 so only two types were compared. bNo sequences were obtained for Symbiodinium C90, so only three types were compared.
