Dynamics of Plant Mitochondrial Genome: Model of a Three-Level Selection Process

Autor: Anne Atlan, R. De Paepe, Béatrice Albert, Pierre-Henri Gouyon, Bernard Godelle

Publikováno v: Genetics. 144:369-382

The plant mitochondrial genome is composed of a set of molecules of various sizes that generate each other through recombination between repeated sequences. Molecular observations indicate that these different molecules are present in an equilibrium

Specific mitochondrial proteins in pollen: presence of an additional ATP synthase beta subunit

Autor: Fernand Vedel, P. Chetrit, R. De Paepe, A Forchioni

Publikováno v: Proceedings of the National Academy of Sciences. 90:5934-5938

A protocol was designed to obtain a pure fraction of pollen mitochondria from the diploid species Nicotiana sylvestris, the female parent of the allotetraploid Nicotiana tabacum. Most organelles were morphologically intact and able to perform in orga

Cytoplasmic male sterility is associated with large deletions in the mitochondrial DNA of two Nicotiana sylvestris protoclones

Autor: R. De Paepe, P. Chetrit, V. Vitart, F. Vedel, S. Gutierres, R. Rios

Publikováno v: Current Genetics. 21:131-137

Two cytoplasmic male-sterile plants (CMSI and CMSII) were obtained by protoplast culture in Nicotiana sylvestris. Both plants showed large deletions (up to 50 kb) in their mitochondrial DNA. Restriction maps of the reorganized regions suggested that

Several nuclear genes control both male sterility and mitochondrial protein synthesis inNicotiana sylvestris protoclones

Autor: Fernand Vedel, Veronique Vitart, D. Prat, R. De Paepe, P. Chetrit, F. Ambard-Bretteville

Publikováno v: Molecular and General Genetics MGG. 222:206-210

Male sterile plants appeared in the progeny of three fertile plants obtained after one cycle of protoplast culture from a fertile botanical line and two androgenetic lines of Nicotiana sylvestris. These plants showed the same foliar and floral abnorm

The lack of mitochondrial complex I in a CMSII mutant of Nicotiana sylvestris increases photorespiration through an increased internal resistance to CO2 diffusion

The cytoplasmic male sterile II (CMSII) mutant lacking complex I of the mitochondrial electron transport chain has a lower photosynthetic activity but exhibits higher rates of excess electron transport than the wild type (WT) when grown at high light

The mitochondrial CMSII mutation of Nicotiana sylvestris impairs adjustment of photosynthetic carbon assimilation to higher growth irradiance

Journal of Experimental Botany, Oxford University Press (OUP), 2006, 57 (9), pp.2075-2085. ⟨10.1093/jxb/erj161⟩

The CMSII mutant of Nicotiana sylvestris, which lacks a functional mitochondrial complex I, was used to investigate chloroplast-mitochondria interactions in light acclimation of photosynthetic carbon assimilation. CMSII and wild-type (WT) plants were
