When we think of extremophiles, organisms adapted to extreme environments, prokaryotes come to mind first. However, the unicellular red micro-alga Galdieria sulphuraria (Cyanidiales) is a eukaryote that can represent up to 90% of the biomass in extreme habitats such as hot sulfur springs with pH values of 0–4 and temperatures of up to 56 °C. This red alga(More)
Ammonia assimilation by the plastidic glutamine synthetase/glutamate synthase system requires 2-oxoglutarate (2-OG) as a carbon precursor. Plastids depend on 2-OG import from the cytosol. A plastidic dicarboxylate translocator 1-[2-OG/malate translocator (DiT1)] has been identified and its substrate specificity and kinetic constants have been analyzed in(More)
During the last 15 years, much progress has been made in discovering genes encoding solute transporters of the inner plastid envelope membrane. For example, genes encoding transporters for phosphorylated intermediates, dicarboxylates, adenine nucleotides, inorganic anions, and monosaccharides have been cloned. In many cases, the corresponding proteins have(More)
A recent strategy for pest control in plants has involved transformation with genes encoding cysteine proteinase inhibitors (cystatins). Little is known, however, about the effects of constitutive cystatin expression on whole plant physiology. The present study using oryzacystatin I (OC-I) expression in transformed tobacco was designed to resolve this issue(More)
