    • Background

    • Results

      • All eukaryotes exhibit splice variation

      • CE and RI prevalence vary by kingdom and by intron length

      • Variably spliced regions exhibit size constraints

      • Most splice variants are not functional

      • Retained introns are associated with weak splice sites

      • Discussion

        • Splice variation reveals mechanisms of splice site recognition
