  1. The number of SSRs of length greater than or equal to 20 bp and 30 bp are reported. The number in parentheses is the number of perfect, i.e. uninterrupted, repeats. Repeats with less than 90% purity are unreported. Prop. is the proportion of all unique sequences that contained an SSR of at least 20 bp or 30 bp.
