Interaction of 2,4-Dichlorophenoxyacetic Acid, Ethylene Chlorohydrin and Glutathione in the Stability of the Microsomal Ribonucleic Acid of Excised Cotton Cotyledons
The nucleic acids ot isolated plant tissues were first shown to be affected by plant growth regulators by Silberger and Skoog (1953). They showed that indoleacetic acid treatment would increase the level of ribonucleic acid (RNA) and deoxyribonucleic acid in tobacco pith tissue. Recently, experiments with excised stems of cucumber seedlings (West, Hanson and Key, 1960), and excised cotton cotyl...
متن کاملInhibition of Auxin-induced Deoxyribonucleic Acid Synthesis and Chromatin Activity by 5-Fluorodeoxyuridine in Soybean Hypocotyl.
Rootless soybean (Glycine max) seedlings were used as a test system to examine the action of auxin on chromatin-directed RNA synthesis. Chromatin from the basal tissue of rootless seedlings (both control and auxin-treated) had RNA synthetic capacity similar to that of chromatin from comparably treated intact seedlings. When DNA synthesis normally induced in the basal tissue by auxin was blocked...
متن کاملInfluence of auxin and incubation on the relative level of polyribosomes in excised soybean hypocotyl.
The influence of incubation and auxin (2,4-D) on polyribosome level in soybean hypocotyl was studied.A marked drop in the relative level of polyribosomes in excised apical or meristematic tissue (0 to 5 millimeters below the cotyledons) occurred during incubation. The addition of auxin to the incubation medium did not affect polyribosome level. A similar decrease in polyribosome level occurred ...
متن کاملHormonal regulation of cell elongation in the hypocotyl of rootless soybean: an evaluation of the role of DNA synthesis.
A method was developed where soybean seedlings were grown without roots to study the influence of hormones of root origin on shoot growth. Excision of the root resulted in inhibition of apical section growth and DNA synthesis and inhibited elongating section growth. A synthetic cytokinin restored DNA synthesis in the apical section, but did not influence growth in either the apical or elongatin...
متن کاملComparison of Auxin-induced and Acid-induced Elongation in Soybean Hypocotyl.
Acid-induced growth was compared to auxin-induced growth. After a transient pH 4-induced increase in the elongation rate was completed, auxin could still induce an enhanced rate of elongation in soybean (Glycine max) hypocotyl segments. This auxin response occurred both when the medium was changed to pH 6 before auxin addition, and when the auxin was added directly to the pH 4 medium. This post...
