| − | Editing of the orfB transcripts
| |
| − | (a) The fertile line
| |
| − | Mitochondrial RNA editing of the orfB transcript was
| |
| − | assessed in the fertile rice line. Fourteen cDNA clones
| |
| − | obtained from cDNA library of fertile rice line were
| |
| − | sequenced. Determination of the orfB cDNA sequence
| |
| − | from overlapping clones from the cDNA library showed
| |
| − | four C®T conversions within the coding region relative
| |
| − | to the orfB genomic sequence.

| − | orfB transcripts of the sterile line have identical 3’ ends
| |
| − | with that of transcripts from the fertile lines
| |
| − | The basis of the observed differences in the orfB gene
| |
| − | transcripts between the sterile and fertile lines was
| |
| − | determined using 3’ RACE. The forward primer OGSP1
| |
| − | (Figure 4) annealed 180 bp downstream of the
| |
| − | initiation codon in the coding region of the orfB gene.
| |
| − | In both the fertile and sterile rice lines, one amplified
| |
| − | band of ~400 bp was obtained
