This binary molecule switches “on” and “off” plant gene expression in response to light (1). Phytochrome controls in a positive or negative way the expression of numerous genes, including its own (2–4). Phy

Plastocyanin is confined to chloroplast-containing tissues, and is not found in roots (Katoh et al., 1961; de Boer et al., 1988; Last and Gray, 1990). Similarly, plastocyanin mRNA is found only in photosynthetic tissues or tissues destined to become phot

Several different interventions were used to lower energy charge (and phosphorylation potential), including norepinephrine (NE) infusion, hypoperfusio

We designed four different accesses of a fiber probe to measure blood velocities, depending upon the objectives of the measurements, i. e., epicardial large coronary vessels, the epicardial small artery and vein, the intram

Heinz Rehkuglere, we have developed a new microscopic system which we termed the “floating objective system”, and which consists of a pair of convex lenses vertically aligned on the same optical axis. The real image on the front focus of a lens facing the heart (floating lens) is transmitted to the back focus of a
