Minimalist Interpretation of Deamination Gradients in Chloroplast Genomes. The minimalist model that can be inferred based on our analyses of various regions between replication origins in all chloroplast genomes suggests presence of A → G gradients in the smaller (Type 2) and larger (Type 4) regions between A1 and A1-C origin copies and A2 and A2-C origin copies on either inverted repeats, which incidentally overlap with the S mall S ingle C opy (SSC) and L arge S ingle C opy (LSC) regions, respectively. These gradients are bi-directional, increasing from the center of each region towards the origins themselves. The directions of these gradients are shown on the representative genome (Zea mays).
