Class I, class II, and class III PABP genes are present in gymnosperm and basal angiosperm species. Comparison of the intron positions in PABP genes from the non-seed plant species P. patens and S. moellendorffii, the gymnosperm P. abies, the basal angiosperm A. trichopoda, and A. thaliana. RRMs (green), PABC domain (blue), RNP1 and RNP2 motifs (lines), and introns (vertical white bars) are indicated. Sequence for the P. abies class I gene was assembled from MA_10436565 and GQ03616_F15.1 whereas sequence for the P. abies class III gene was assembled from MA_36585 and UCPabies_isotig05724. Complete sequence for P. abies class I gene MA_18005 and class II gene MA_10435577 was not available. The K. flaccidum gene shown, the four P. patens genes, and three of four S. moellendorffii genes are progenitor PABP genes but are included with class I genes for comparison.
