Fig. 4From: accD nuclear transfer of Platycodon grandiflorum and the plastid of early CampanulaceaeBorder sequences between the nr-accD exons and introns in Campanulaceae species. The nr-accD of Campanulaceae contains a nuclear intron. The first row shows the aligned border of the accD.e1 and accD introns and the second row shows the aligned border of accD and accD.e2 introns. The dot indicates the same sequence of the first line sequence and ‘-’ indicates absence of the sequence or gapBack to article page
