A cytoplasmic male sterility-associated mitochondrial peptide in common bean is post-translationally regulated.
Cytoplasmic male sterility in the common bean plant is associated with a dominant mitochondrial mutation designated pvs-or f 239 (for Phaseolus vulgaris sterility sequence open reading frame 239). The sequence is transcribed in both vegetative and reproductive tissues, but the translation product, ORF239, is present only in reproductive tissues. We present evidence to support a model of post-tr...
متن کاملFertility Restoration Is Associated with Loss of a Portion of the Mitochondrial Genome in Cytoplasmic Male-Sterile Common Bean.
Restoration of pollen fertility to cytoplasmic male-sterile common bean by nuclear gene Fr is accompanied by mitochondrial (mt) DNA rearrangements within restored plants. These rearrangements are also observed upon spontaneous cytoplasmic reversion to fertility. An mtDNA fragment of at least 25 kilobases was lost from the genome upon restoration or reversion. This fragment contained DNA segment...
متن کاملA mitochondrial DNA sequence is associated with abnormal pollen development in cytoplasmic male sterile bean plants.
Cytoplasmic male sterility (CMS) in common bean is associated with the presence of a 3-kb unique mitochondrial sequence designated pvs. The pvs sequence encodes at least two open reading frames (297 and 720 bp in length) with portions derived from the chloroplast genome. Fertility restoration by the nuclear restorer gene Fr results in the loss of this transcriptionally active unique region. We ...
متن کاملUnusual mitochondrial genome organization in cytoplasmic male sterile common bean and the nature of cytoplasmic reversion to fertility.
Spontaneous reversion to pollen fertility and fertility restoration by the nuclear gene Fr in cytoplasmic male sterile common bean (Phaseolus vulgaris L.) are associated with the loss of a large portion of the mitochondrial genome. To understand better the molecular events responsible for this DNA loss, we have constructed a physical map of the mitochondrial genome of a stable fertile revertant...
