Homocysteine Biosynthesis in Green Plants
Optimal conditions for biosynthesis of cystathionine with crude extracts of green plants were determined. The specific activities observed under these conditions are considerably higher than those initially detected (GIOVANELLI, J., AND MUDD, S. H. (1966) Biochem. Biophys. Res. Commun. 25, 366), and compare favorably with those of bacterial extracts. At near saturating concentrations of homoser...
متن کاملLight Production by Green Plants
1. Green plants have been found to emit light of approximately the same color as their fluorescent light for several minutes following illumination. This light is about 10(-3) the intensity of the fluorescent light, about one-tenth second after illumination below saturation or 10(-6) of the intensity of the absorbed light. 2. The decay curve follows bimolecular kinetics at 6.5 degrees C. and re...
متن کاملGreen plants as intelligent organisms.
Intelligent behaviour, even in humans, is an aspect of complex adaptive behaviour that provides a capacity for problem solving. This article assesses whether plants have a capacity to solve problems and, therefore, could be classified as intelligent organisms. The complex molecular network that is found in every plant cell and underpins plant behaviour is described. The problems that many plant...
متن کاملTowards Adaptive Robotic Green Plants
Fig. 1. Prototype of the cyborg, the final version will feature a casing hiding the electronics. Humans often use green plants as furniture in their built environments. More generally, the status of plants as living beings is highly dependent on their lack of mobility. The goal of this project, which is a collaboration between artists and roboticists, is to lead the general public to a question...
متن کاملGreen light for gene targeting in plants.
P recision engineering of eukaryotic organisms requires efficient techniques for homology-based replacement of an endogenous gene by an introduced gene, a process termed gene targeting (GT). Because foreign DNA is preferentially integrated by nonhomologous recombination in plants and animals, special strategies are needed to increase the frequency and facilitate the detection of GT. Developing ...
