Promoters of nuclear‐encoded respiratory chain Complex I genes from Arabidopsis thaliana contain a region essential for anther/pollen‐specific expression

Abstract: Regulatory promoter regions responsible for the enhanced expression in anthers and pollen are defined in detail for three nuclear encoded mitochondrial Complex I (nCl) genes from Arabidopsis thaliana. Specific regulatory elements were found conserved in the 5' upstream regions between three different genes encoding the 22 kDa (PSST), 55 kDa NADH binding (55 kDa) and 28 kDa (TYKY) subunits, respectively. Northern blot analysis and transgenic Arabidopsis plants carrying progressive deletions of the promoters fus… Show more

“…On the other hand, a general increase in the expression of nuclear genes encoding mitochondrial components is thought to occur in flowers with respect to other organs (Huang et al, 1994;Landschü tze et al, 1995;Felitti et al, 1997;Heiser et al, 1997;Zabaleta et al, 1998). However, since these analyses have dealt with total RNA preparations, differences in expression in specific cell types have not been reported, except for the ␤-subunit of ATP synthase in sunflower (Balk and Leaver, 1998).…”

“…These authors, using a homologous probe, have observed accumulation of transcripts encoding this subunit in meiocytes and tapetal cells at premeiosis and only in tapetal cells at later stages (Balk and Leaver, 1998). Using a different approach, Zabaleta et al (1998) have observed that the promoters of three nuclear genes encoding complex I components direct enhanced ␤-glucuronidase expression in anthers. Our results on cytochrome c gene expression seem to correlate with those obtained by Balk and Leaver (1998) and Zabaleta et al (1998), although we were not able to detect specific expression in mature pollen.…”

“…At present, only a few promoters of mitochondrial protein genes have been analyzed (Zabaleta et al, 1998;Satoh et al, 2002;Welchen et al, 2004;Dojcinovic et al, 2005;Weltmeier et al, 2006;González et al, 2007;Ho et al, 2007). However, to the best of our knowledge, the SDH2-3 promoter is the first embryo-specific promoter characterized for a mitochondrial respiratory protein and the first gene promoter from TCA cycle enzymes to be characterized in plants.…”
