Concentration of Indole-3-acetic Acid and Its Derivatives in Plants.
TLDR
All plant tissues examined contained most of their IAA as derivatives, either esterified or as a peptide; the cereal grains examined contained mainly ester IAA; and the legume seeds examined contain mainly peptidyl IAA.
Chemistry and Physiology of the Bound Auxins

iaglu, a gene from Zea mays involved in conjugation of growth hormone indole-3-acetic acid.
TLDR
Protein synthesized by Escherichia coli that contained cloned 1-O-beta-D-indol-3-ylacetyl-glucose complementary DNA (cDNA) was catalytically active and the predicted amino acid sequence of the cDNA was confirmed by amino-terminal sequencing of the purified enzyme.
Enzymic synthesis of 1-O-indol-3-ylacetyl-beta-D-glucose and indol-3-ylacetyl-myo-inositol.
TLDR
Indol-3-ylacetyl-myo-inositol synthase is specific for UDP-glucose and, at the stage of purity tested, the enzyme will use either indol- 3-ylacetic acid or naphthalene-1-ACetic acid, but not 2.4-dichlorophenoxyacetic Acid, as glucose acceptor.
Enzymatic reactions involving sulfate, sulfite, selenate, and molybdate.
Photo-regulation of the ratio of ester to free indole-3-acetic acid.
TLDR
It is concluded that one mechanism for regulation of plant growth is alteration of the ratio of free to conjugated hormone by environmental stimuli.
Bifunctional indole-3-acetyl transferase catalyses synthesis and hydrolysis of indole-3-acetyl-myo-inositol in immature endosperm of Zea mays
TLDR
Results of gel filtration and analytical SDS-PAGE suggest that the native enzyme exists as both a monomeric and homo- or heterodimeric form (110-130 kDa).
Metabolism and Synthesis of Indole-3-Acetic Acid (IAA) in Zea mays (Levels of IAA during Kernel Development and the Use of in Vitro Endosperm Systems for Studying IAA Biosynthesis)
TLDR
Endosperm preparations of Z. mays are suggested to be suitable for study of the mechanism(s) of IAA biosynthesis because they have high rates of synthesis, show stability to freezing, enabling enzyme storage, and provide a system with a known rate of in situ synthesis.
Enzymic synthesis of indole-3-acetyl-1-O-beta-d-glucose. II. Metabolic characteristics of the enzyme.
The synthesis of indole-3-acetyl-1-O-beta-D-glucose from indole-3-acetic acid (IAA) and uridine diphosphoglucose (UDPG) has been shown to be a reversible reaction with the equilibrium away from ester
