Cell type-specific loss of atp6 RNA editing in cytoplasmic male sterile Sorghum bicolor.
RNA editing and cytoplasmic male sterility are two important phenomena in higher plant mitochondria. To determine whether correlations might exist between the two, RNA editing in different tissues of Sorghum bicolor was compared employing reverse transcription-PCR and subsequent sequence analysis. In etiolated shoots, RNA editing of transcripts of plant mitochondrial atp6, atp9, nad3, nad4, and...
متن کاملSuppressed expression of Retrograde-Regulated Male Sterility restores pollen fertility in cytoplasmic male sterile rice plants.
Conflict/reconciliation between mitochondria and nuclei in plants is manifested by the fate of pollen (viable or nonviable) in the cytoplasmic male sterility (CMS)/fertility restoration (Rf) system. Through positional cloning, we identified a nuclear candidate gene, RETROGRADE-REGULATED MALE STERILITY (RMS) for Rf17, a fertility restorer gene for Chinese wild rice (CW)-type CMS in rice (Oryza s...

متن کاملA pentatricopeptide repeat-containing gene restores fertility to cytoplasmic male-sterile plants.
Known in over 150 species, cytoplasmic male sterility is encoded by aberrant mitochondrial genes that prevent pollen development. The RNA- or protein-level expression of most of the mitochondrial genes encoding cytoplasmic male sterility is altered in the presence of one or more nuclear genes called restorers of fertility that suppress the male-sterile phenotype. Cytoplasmic male sterility/rest...
متن کاملMitochondrial DNA rearrangement associated with fertility restoration and cytoplasmic reversion to fertility in cytoplasmic male sterile Phaseolus vulgaris L.
Restoration of pollen fertility to cytoplasmic male sterile (CMS) Phaseolus vulgaris by a nuclear restorer gene provides a system for studying nuclear-cytoplasmic interactions. Introduction of a nuclear restorer gene to this CMS line of P. vulgaris (CMS-Sprite) results in a mitochondrial genome rearrangement similar to that observed upon spontaneous cytoplasmic reversion to fertility. Three spo...
