Gene localization on the chloroplast DNA of the maiden hair fern;Adiantum capillus-veneris

Gene maps were constructed for the inverted repeat region and for the adjacent large single copy region of the chloroplast genome of the maiden hair fern,Adiantum capillus-veneris L. Gene order and organization was very different from the typical angiosperm chloroplast genome (e.g. tobacco). Elongation of inverted repeat and a minimum of two inversions must be postulated to account for the unusual genome structure.
