Alterations in Nuclear Ribonucleic Acid Metabolism Induced by Kinetin
نویسنده
چکیده
Removal of deoxyribonucleic acid from meristematic onion root cells grown in solutions of kinetin, followed by metachromatic staining in azure B bromide, indicated the presence of appreciable amounts of ribonucleic acid in nuclei exposed to the cell division factor.

Nuclear Radiation and Thyroid Cancer; A Systematic Review
Background: The increasing prevalence of thyroid cancer among the survivors of atomic bomb attacks in Japan, nuclear fallout in the Marshall Islands, and Chernobyl nuclear power plant accident indicate a strong relationship between nuclear radiation and the occurrence of thyroid cancer. Materials and Methods: Systematic researches were conducted in the medical database of the American National ...

Edstrom's microphoresis technique has been employed to determine the quantitative alterations in nucleic acid content and base composition of individual cells associated with the initiation of bud primordia in Funaria hygrometrica. The filamentous protonema of this moss initiates bud cells which through repeated divisions form the leafy gametophores. The cytokinin, 6-furfurylaminopurine (kineti...
متن کاملMechanism of a Synergistic Effect of Kinetin on Auxin-induced Ethylene Production: Suppression of Auxin Conjugation.
In hypocotyl segments of mung bean (Phaseolus mungo L.) seedlings, exogenously supplied indoleacetic acid was rapidly conjugated mainly into indoleacetylaspartic acid, which was inactive in inducing ethylene production. Kinetin is known to stimulate indoleacetic acid-induced ethylene production. The mechanism of kinetin action on indoleacetic acid-induced ethylene production by hypocotyl segmen...
متن کاملPhenylpropanoid Metabolism in Suspension Cultures of Vanilla planifolia Andr. : IV. Induction of Vanillic Acid Formation.
Kinetin is used as an elicitor to induce vanillic acid formation in cell suspension cultures of Vanilla planifolia. Maximal induction is observed at a kinetin concentration of 20 micrograms per gram of fresh weight of cells. Vanillic acid synthesis is observed a few hours after elicitation. The effects of kinetin on the activity of some enzymes of the phenylpropanoid pathway, i.e. phenylalanine...
متن کاملCorrelative Studies on Plant Growth and Metabolism. III. Metabolic Changes Accompanying Inhibition of the Longitudinal Growth of Stem and Root by Kinetin.
Kinetin-induced expansion of lettuce (Lactuca sativa) cotyledons and inhibition of root are accompanied by parallel changes in protein nitrogen. However, during its inhibition of the longitudinal growth and water uptake of hypocotyl and pea (Pisum sativum) epicotyl sections kinetin markedly stimulates protein synthesis. Kinetin seems to separate auxin induced effects on protein synthesis and wa...
