The canonical group I intron in the plastid tRNA-Leu (trnL) gene. (A) Multiple alignments of plastid trnL genes from E. siliculosus (Es) and F. vesiculosus (Fv), showing the position of the group I intron located in the F. vesiculosus trnL2 gene. Structural features of tRNA are indicated on the two first lines. (B) Schematic phylogeny of the phaeophytes (redrawn from [48]), showing the presence (+) and absence (-) of the trnL intron in the different orders.
