a Introns were classified according to Michel and Westhof [44]. The subcategory of the Ov.petB.1 intron could not be identified unambiguously.

b L followed by a number refers to the loop extending the base-paired region identified by the number.

c The conserved motif in the predicted homing endonuclease is given, with the number of copies of the LAGLIDADG motif indicated in parentheses.
