متن کاملMyo-Inositol Esters of Indole-3-acetic Acid as Seed Auxin Precursors of Zea mays L.
Indole-3-acetyl-myo-inositol esters constitute 30% of the low molecular weight derivatives of indole-3-acetic acid (IAA) in seeds of Zea mays. [(14)C]Indole-3-acetyl-myo-inositol was applied to a cut in the endosperm of the seed and found to be transported from endosperm to shoot at 400 times the rate of transport of free IAA. The rate of transport of indole-3-acetyl-myo-inositol from endosperm...
متن کاملGas-Liquid Chromatographic Analysis of Indole-3-acetic Acid Myoinositol Esters in Maize Kernels.
An improved method of fractionating the myoinositol esters of indoleacetic acid (IAA) from maize kernels by gas-liquid chromatography has been developed. Mass spectrometry was employed as an aid in identification of the esters. Maize kernels contain three groups of esters of IAA: (a) IAA myoinositols, (b) IAA myoinositol arabinosides, and (c) IAA myoinositol galactosides. Each group has three c...
متن کاملOxindole-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...
متن کاملIsolation and characterization of esters of indole-3-acetic acid from the liquid endosperm of the horse chestnut (Aesculus species).
Esters of indole-3-acetic acid were extracted and purified from the liquid endosperm of immature fruits of various species of the horse chestnut (Aesculus parviflora, A. baumanni, A. pavia rubra, and A. pavia humulis). The liquid endosperm contained, at least 12 chromatographically distinct esters. One of these compounds was purified and characterized as an ester of indole-3-acetic acid and m...
