Fig. 3

Nucleotide substitutions mainly occurred in the plastid-derived sequence in new sequenced CMS-S subtypes. a Mutation bias in plastid-derived DNA sequences (mtpt) of CMS-S mitochondrial genome. Orange dots in upper panel represent nucleotides mutation in each subtypes that compared with referee. Mtpt sequences are labeled in green color. Lower panel shows individual nucleotide mutations in the representative 3658-bp mtpt sequence and chloroplast homolog among NB, CMS-Sa, and CMS-Sb. Mt, mitochondrial; Pt, plastid. b Mutation rate in mtpt and non-mtpt sequence of CMS-Sa and CMS-Sb, calculated as the number of substitution or indel per 10,000 nucleotide
