A chloroplast DNA mutational hotspot and gene conversion in a noncoding region near rbcL in the grass family (Poaceae).

Current genetics - 1 Oct 1993

Morton B R, Clegg M T

Abstract excerpt

The noncoding DNA region of the chloroplast genome, flanked by the genes rbcL and psaI (ORF36), has been sequenced for seven species of the grass family (Poaceae). This region had previously been observed as a hotspot area for length mutations. Sequence comparison reveals that short duplications, probably resulting from slipped-strand mispairing, account for many small length differences between sequences but...
