Substances essential for a red, far-red light reversible attachment of mung bean root tips to glass.
In a recent publication (5), I reported that several substances are necessary for barley root tips to show a rapid photoreversible attachment to wet glass surfaces. These substances are: 3-indoleacetic acid (IAA), adenosine-5'-triphosphate l(ATP), L-ascorbic acid (AA), Mnn2+, Mg2+, and K+. Since mung bean root tips also show a tendency to adhere to wet glass surfaces, their requirement for thes...
متن کاملIndoleacetic Acid and abscisic Acid antagonism: I. On the phytochrome-mediated attachment of mung bean root tips on glass.
The phytochrome-mediated attachment of mung bean (Phaseolus vulgaris L., var. Oklahoma 612) root tips on glass is quickly affected by indoleactic acid and abscisic acid at concentrations of 10 nm or less. Indoleacetic acid induces detachment, whereas abscisic acid induces attachment. Both plant regulators rapidly antagonize the action of the other. None of several cytokinins, gibberellins, and ...
متن کاملThe Reversible Inhibition by Red and Far-Red Light of Auxin-Induced Lateral Root Initiation in Isolated Pea Roots.
Lateral root formation induced in cultured isolated roots by decapitation can be inhibited by a single short exposure to white light and red light inhibits lateral root formation much more effectively than blue or green light (10). With the development of knowledge about phytochrome, a photomorphogenetically active red/far-red pigment system (3, 7), it became of interest to know whether the phy...
متن کاملOn the involvement of acetylcholine in phytochrome action.
In a recent publication Jaffe (1) presented data which implicated acetylcholine as the causative agent in the phytochrome-mediated attachment of mung bean root tips on a glass surface. Since ACh2 is responsible for the bioelectric potential changes in certain nerve cells of animals, proof of its participation in any phytochrome-mediated process is of great significance in elucidating the mechan...
