Quantitative data on nitric oxide (NO) production by plants, and knowledge of participating reactions and rate limiting factors are still rare. We quantified NO emission from tobacco (Nicotiana… (More)
The cyanobacterium Synechocystis sp. strain PCC 6803 possesses two CO(2) uptake systems and two HCO(3)(-) transporters. We transformed a mutant impaired in CO(2) uptake and in cmpA-D encoding a… (More)
Nitric oxide (NO) is a widespread signaling molecule, and numerous targets of its action exist in plants. Whereas the activity of NO in erythrocytes, microorganisms, and invertebrates has been shown… (More)
Recent experiments indicate that nitric oxide (NO) plays a pivotal role in disease resistance and several other physiological processes in plants. However, most of the current information about the… (More)
A hypersensitive response (HR) was induced in tobacco leaves and cell suspensions by the fungal elicitor cryptogein, and NO production was followed by chemiluminescence and occasionally by… (More)
The mechanism of the post-translational modulation of nitrate reductase activity (NR, EC 1.6.6.1) is briefly summarized, and it is shown that by this mechanism nitric oxide production through NR is… (More)
NO 3 − is a major nitrogen source for plant nutrition, and plant cells store NO 3 − in their vacuoles. Here, we report that a unique compost made from marine animal resources by thermophiles… (More)
The spinach (Spinacia oleracea L. (cv. Hoyo) nitrate reductase inactivator (NRI) is a novel protein that irreversibly inactivates NR. Using degenerate primers based on an N-terminal amino acid… (More)
Tendrils are filamentous plant organs that coil on contact with an object, thereby providing mechanical support for climbing to reach more sunlight. Plant tendrils are considered to be modified… (More)
cotA, a homologue of cemA that encodes a chloroplast envelope membrane protein, was cloned from Synechococcus PCC7942. The gene encodes a protein of 421 amino acids, which is similar in size to CotA… (More)
