Summary In this work, we provide evidence for the existence of a nuclear factor involved in the splicing of a specific mitochondrial intron in higher plants. In the Nicotiana sylvestris nuclear NMS1 mutant, defective in both vegetative and reproducti

In the Nicotiana sylvestris CMSII mutant, a recombination-mediated change 5' to the first exon of the mitochondrial nad1 gene is associated with lack of the NADH:ubiquinone oxidoreductase (complex I) NAD1 subunit

We previously reported that the Nicotiana sylvestris CMSII mutant mitochondrial DNA carried a large deletion. Several expressed sequences, most of which are duplicated, and the unique copy of the nad7 gene encoding the NAD7 subunit of the NADH:ubiqui

Unlike other plant species, two copies of nad3 are present in Nicotiana sylvestris mitochondria. Both are localized downstream from an open reading frame (orf87 ), and are associated with either rps12 or the first exon of the nad1 gene. The orf87-nad

A promoter element active in run-off transcription controls the expression of two cistrons of nad and rps genes in Nicotiana sylvestris mitochondria

The expression of two mitochondrial gene clusters (orf87-nad3-nad1/A and orf87-nad3-rps12) was studied in Nicotiana sylvestris. 5' and 3' termini of transcripts were mapped by primer extension and nuclease S1 protection. Processing and transcription

Organization and expression of the mitochondrial genome in the Nicotiana sylvestris CMSII mutant

Autor: Sophie Gutierres, Fernand Vedel, Béatrice Albert, Christine Lelandais, R. De Paepe, P. Chetrit, Bernard Godelle

Previous analyses suggested that the Nicotiana sylvestris CMSII mutant carried a large deletion in its mitochondrial genome. Here, we show by cosmid mapping that the deletion is 60 kb in length and contains several mitochondrial genes or ORFs, includ

Lack of mitochondrial and nuclear-encoded subunits of complex I and alteration of the respiratory chain in Nicotiana sylvestris mitochondrial deletion mutants

Autor: Hervé Degand, Fernand Vedel, Sophie Gutierres, Christine Lelandais, P. Chetrit, Rosine De Paepe, Mohammed Sabar, Philippe Diolez, Yaroslav de Kouchkovsky, Marc Boutry

Publikováno v: Proceedings of the National Academy of Sciences of the United States of America. 94(7)

We previously have shown that Nicotiana sylvestris cytoplasmic male sterile (CMS) mutants I and II present large mtDNA deletions and that the NAD7 subunit of complex I (the main dehydrogenase of the mitochondrial respiratory chain) is absent in CMS I
