Flux of protons released by wild type and ferritin over-expressor tobacco plants : effect of phosphorus and iron nutrition

2003

Abstract Tobacco ( Nicotiana tabacum ) plants over-expressing the iron storage protein ferritin, either in the cytoplasm or in the plastids, were grown under various P and Fe conditions. The crossed effects of both the genotypes and the environmental conditions on iron and chlorophyll concentrations in leaves, ferric reductase (EC 1.6.99.13) and plasmalemma H + -ATPase (EC 3.6.3.6) activities in roots, and fluxes of H + released by roots were determined. The increase in leaf Fe concentration observed in plants over-expressing ferritin was accompanied by an increase in root ferric reductase and H + -ATPase activities. Iron deficient conditions induced a decrease in Fe and chlorophyll concent…
