Inhibition of Polar Indole-3-acetic Acid Transport by Cycloheximide.
Cycloheximide inhibits polar indoleacetic acid transport in midrib tissues of leaves of citrus (Citrus sinensis [L.] Osbeck) and poplar (Populus deltoides Bartr.) as measured by the donor-receiver agar cylinder technique. It appears that the mechanism of auxin transport inhibition by cycloheximide consists in arresting protein synthesis and not in the disruption of energy flow. The interpretati...
متن کاملTransport of indole-3-butyric acid and indole-3-acetic acid in Arabidopsis hypocotyls using stable isotope labeling.
The polar transport of the natural auxins indole-3-butyric acid (IBA) and indole-3-acetic acid (IAA) has been described in Arabidopsis (Arabidopsis thaliana) hypocotyls using radioactive tracers. Because radioactive assays alone cannot distinguish IBA from its metabolites, the detected transport from applied [3H]IBA may have resulted from the transport of IBA metabolites, including IAA. To test...

متن کاملTransport of the two natural auxins, indole-3-butyric acid and indole-3-acetic acid, in Arabidopsis.
Polar transport of the natural auxin indole-3-acetic acid (IAA) is important in a number of plant developmental processes. However, few studies have investigated the polar transport of other endogenous auxins, such as indole-3-butyric acid (IBA), in Arabidopsis. This study details the similarities and differences between IBA and IAA transport in several tissues of Arabidopsis. In the infloresce...
متن کاملExplanation of the Inhibition of Root Growth Caused by Indole-3-Acetic Acid'
Summii1stary. Low concentrations of indole-3-acetic acid inhibit the growth of pea root sections by indticing the formation of the growth regtilator, ethylene gas. Ethylene is produced within 15 to 30 minutes after inidole-3-acetic acid is applied and roots begin to swell immediately after they are exposed to the gas. Carbon dioxide competitively inhibits ethylene action in roots, impedles thei...
