One-tasiAP2-one-tasiARF	Andreaeopsida; Polytrichopsida; Tetraphidopsida; Bryopsida/Timmiidae; Bryopsida/Funariidae; Bryopsida/Bryidae; Bryopsida/Dicranidae
TAS6-TAS3	Bryopsida/Funariidae; Bryopsida/Bryidae; Bryopsida/Dicranidae
One-tasiARF only	Equisetopsida
One-tasiARF and two-tasiARF species	Marattiopsida
Two-tasiARF (no tandem repeat)	Marattiopsida
One-tasiARF and two-tasiARF species	Polypodiopsida
One-tasiARF and two-tasiARF species	Spermatophyta*
No TAS3 loci revealed	Lycopodiopsida; Sphagnopsida

See text for details. *Spermatophyta species form a group, which includes several classes.
