Polyadenylation accelerates the degradation of the mitochondrial mRNA associated with cytoplasmic male sterility in sunflower.
In sunflower, PET1-cytoplasmic male sterility is correlated with the presence of a novel mitochondrial gene (orf522) located 3' to the atpA gene. The dicistronic atpA-orf522 transcripts are preferentially destabilized in male florets of 'restored to fertility' plants as compared with sterile plants. In this report, we show that atpA-orf522 transcripts may be polyadenylated in vivo at their 3' t...
متن کاملRNA editing of transcripts of a chimeric mitochondrial gene associated with cytoplasmic male-sterility in Brassica.
The orf224 gene is a chimeric open reading frame associated with the Polima or pol cytoplasmic male sterility of Brassica napus. The first 58 codons and 5' upstream region of orf224 are derived from a conventional mitochondrial gene, orfB, while the origin of the remaining portion of the gene is unknown. Transcripts of the orf224 gene were found to be edited at a single site in the region of th...
متن کاملUnique Changes in Mitochondrial Genomes Associated with Reversions of S-Type Cytoplasmic Male Sterility in Maizemar
Cytoplasmic male sterility (CMS) in plants is usually associated with the expression of specific chimeric regions within rearranged mitochondrial genomes. Maize CMS-S plants express high amounts of a 1.6-kb mitochondrial RNA during microspore maturation, which is associated with the observed pollen abortion. This transcript carries two chimeric open reading frames, orf355 and orf77, both unique...
متن کاملldentification of a Mitochondrial Protein Associated with Cytoplasmic Male Sterility in Petunia
The petunia fused gene ( pcf ), which is associated with cytoplasmic male sterility (CMS), is composed of sequences derived from atp9, coxll, and an unidentified reading frame termed urfS. To determine whether the pcf gene is expressed at the protein level, we produced antibodies to synthetic peptides specified by the coxll and urfs portions of the pcf gene. Anti-COXII peptide antibodies recogn...
متن کاملIdentification of a mitochondrial protein associated with cytoplasmic male sterility in petunia.
The petunia fused gene (pcf), which is associated with cytoplasmic male sterility (CMS), is composed of sequences derived from atp9, coxII, and an unidentified reading frame termed urfS. To determine whether the pcf gene is expressed at the protein level, we produced antibodies to synthetic peptides specified by the coxII and urfS portions of the pcf gene. Anti-COXII peptide antibodies recogniz...
