OrfB

Please input one-sentence summary here.

Annotated Information

Function

Please input function information here. The editing of the orfB gene ~1.1 kb transcript co-segregated with fertility restoring alleles in a segregating population of F2 progeny of restored hybrid F1 plants.

Expression

Please input expression information here. 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.

Evolution

Please input evolution information here.

You can also add sub-section(s) at will. 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
