Subcellular immunocytochemical analysis detects the highest concentrations of glutathione in mitochondria and not in plastids

Zechmann, B. ; Mauch, Felix ; Sticher, Liliane ; Müller, M.

In: Journal of Experimental Botany, 2008, vol. 59, no. 14, p. 4017-4027

The tripeptide glutathione is a major antioxidant and redox buffer with multiple roles in plant metabolism. Glutathione biosynthesis is restricted to the cytosol and the plastids and the product is distributed to the various organelles by unknown mechanisms. In the present study immunogold cytochemistry based on anti-glutathione antisera and transmission electron microscopy was used to...

Evolution of the cutinase gene family: Evidence for lateral gene transfer of a candidate Phytophthora virulence factor

Belbahri, Lassaad ; Calmin, Gautier ; Mauch, Felix ; Andersson, Jan O.

In: Gene, 2008, vol. 408, no. 1-2, p. 1-8

Lateral gene transfer (LGT) can facilitate the acquisition of new functions in recipient lineages, which may enable them to colonize new environments. Several recent publications have shown that gene transfer between prokaryotes and eukaryotes occurs with appreciable frequency. Here we present a study of interdomain gene transfer of cutinases – well documented virulence factors in fungi –...
