Growth of Parthenocissus tricuspidata tissue cultured on media containing aza analogues of indole-3-acetic acid & indole-3-propionic acid

Growth of Parthenocissus tricuspidata tissue cultured on media containing aza analogues of indole-3-acetic acid & indole-3-propionic acid.

Several years ago, Robison and Robison (5) reported the synthesis of some compounds of biological interest. Among these were 7-aza-indole-3-acetic acid (AIAA) and 7-aza-indole-3-propionic acid (AIPA), aza analogues of indole-3-acetic acid (IAA), and indole-3-propionic acid (IPA). It was apparent that such compounds might be anti-metabolites of auxin, in the same manner that azaguanine has prove...

The Effect of Indole-3-Acetic Acid on Datura Embryos.

Conversion of indole-3-ethanol to indole-3-acetic Acid in cucumber seedling shoots.

Indoleethanol-(14)C was applied to intact cucumber seedlings and to hypocotyl segments. The presence of indoleacetic acid-(14)C in tissue extracts was demonstrated by thin layer radiochromatography. There was no evidence of conversion of indoleacetic acid to indoleethanol. It is suggested that the growth-promoting activity of indoleethanol is due to its conversion to indoleacetic acid.

Oxindole-3-acetic Acid, an Indole-3-acetic Acid Catabolite in Zea mays.

A prior study (13) from this laboratory showed that oxidation of exogenously applied indole-3-acetic acid (IAA) to oxindole-3-acetic acid (OxIAA) is the major catabolic pathway for IAA in Zea mays endosperm. In this work, we demonstrate that OxIAA is a naturally occurring compound in shoot and endosperm tissue of Z. mays and that the amount of OxIAA in both shoot and endosperm tissue is approxi...
