Boron-induced Bioelectric Field Change in Mung Bean Hypocotyl.
Low concentrations of boron were found to affect the bioelectric field potentials of hypocotyls excised from 4-day-old mung bean (Phaseolus aureus cv. Oklahoma 612) seedlings grown in darkness and irradiated with red light. The significance of this effect is discussed in relation to the possible role of boron in some membrane function.
متن کاملSubstances 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 کاملFine Structure of Protein-storing Plastids in Bean Root Tips
The fine structure of leucoplasts in root tip cells of Phaseolus vulgaris L. has been studied in material fixed in glutaraldehyde followed by osmium tetroxide and poststained in uranyl acetate and lead citrate. Plastid development has been followed from the young stages in and near the meristematic region, through an ameboid stage, to the larger forms with more abundant storage products in the ...
متن کاملAltered Gene Expression during Auxin-Induced Root Development from Excised Mung Bean Seedlings.
Changes in the pattern of protein synthesis and in the translatable mRNA population have been examined during auxin-induced root development from excised mung bean seedlings. Several proteins, predominantly of low molecular weight and high pI, as shown by two-dimensional polyacrylamide gel electrophoresis, are synthesized specifically by auxin-treated tissue. These auxin-induced proteins appear...
