Table 1 List of taxa analysed with observed sequence length range for the D1-D2 fragment in the final alignment [see additional file for further details]

From: An evaluation of LSU rDNA D1-D2 sequences for their use in species identification

Taxa number of species D1-D2 fragment length range (bp)
Teleostei 41° 1041–1186
Cyclostomata 1 1138
Nematoda 17 791–1017
Hirudinea 5 954–1034*
Mollusca 9 986–1005*
Crustacea 5 899–1221*
Chelicerata 1 1066
Insecta 70 945–1302*
  1. * includes sequences amplified with primer rev2, which are in the final alignment 48 bp shorter than those done with rev1.
  2. ° without the sequences of Cottus (N = 27) and Aphyosemion (N = 56) which are within the length range for teleosts.
