Schematic representation of the recombinant contig RC-I. a The P-3 region in cv. Alwara, amplified using the primer pair rpl5midR/nad6 (1992 bp). The positions of nucleotide substitutions and insertions/deletions described in Table 2 are shown in Italic figures. Homologous regions with four reads (a to d) from pollen transcripts are shown by blue lines. A108-bp region and a 105-bp region with high homology (> 94%) to those in M02 are shown by striped boxes. The 108-bp sequence contained the first 25 bp sequence of rps10. b RC-I in three T-CMS clones. c Hypothesized circular molecule that amplified the 859-bp band and coexisted substoichiometrically with RC-IÂ
