Plant Cell 1997, 9:1781-1790. IAN-insensitive nit1 mutants and IAN-supersensitive NIT2 overexpressors were isolated, demonstrating that both NIT1 and NIT2 can hydrolyze IAN in planta. Stable isotope labeling of intact plants showed that the nit1 mutant metabolized exogenous IAN normally, and the NIT2 overexpressor had increased IAN turnover

Plant Cell Physiol 1998, 39:433-442. Arabidopsis encodes at least four aldehyde oxidases. The mRNA for one of these genes, AtAO-1, accumulates in the sur1 (rty) mutant, correlating with increased AO activity and higher IAA levels in this mutant thereby implicating aldehyde oxidase in IAA synthesis.

Plant Physiol 1998, 116:687-693. Aldehyde oxidase activity with a preference for indole acetaldehyde is increased in the sur1 (rty) mutant. IAA levels are also elevated in this mutant, suggesting that the increased aldehyde oxidase activity is responsible for increased IAA synthesis.

The IAA-Ala insensitive iar3 mutant was isolated, and the defective gene shown to encode an IAA conjugate hydrolase with specificity for IAA-Ala. The IAR3 gene is similar to the previously isolated ILR1 gene [32] and at least four additional ILR1-like (ILL) genes in Arabidopsis.

Plant Physiol 1997, 115:817-826. The authors use differential display to isolate cDNAs induced by wounding or JA. One of these genes, JR3, is 96% identical to IAR3, which encodes an IAA conjugate hydrolase [33••]. JR3 induction by wounding is blocked in the JA-insensitive coi1 mutant.

Plant J 1998, 13:153-165. A pharmacological approach is used to determine that wound signal transduction in Arabidopsis involves reversible phosphorylation. JR3 [35•] is unique among the JA-induced genes studied in that it is induced by cycloheximide and its induction by JA is not reversed by auxin. The authors suggest that JR3 might dampen the JA response by increasing IAA levels.

High temperature is found to promote hypocotyl elongation in the light, and is accompanied by an increase in free and conjugated IAA levels. The expansion is specifically blocked in IAA transport and response mutants.

The authors measured IAA turnover in wild-type and mutant duckweed fronds under various light conditions. For wild-type, IAA levels remain constant in either continuous light or darkness due to adjustments in the rates of biosynthesis and turnover. A feedback-insensitive anthranilate synthase mutant accumulated IAA, presumably because IAA biosynthesis rates were less well modulated.

46. Sztein AE, Cohen JD, García de la Fuente I, Cooke TJ: Auxin metabolism in mosses and liverworts. Amer J Bot 1999, in press. IAA metabolism was characterized in five liverworts, four mosses, and two tracheophytes. The liverworts and mosses have low levels of both free and conjugated IAA, whereas the tracheophhytes have low free IAA but high levels of conjugates. Conjugation rates are faster in the mosses and tracheophytes than in the liverworts.

48. Östin A, Kowalyczk M, Bhalerao RP, Sandberg G: Metabolism of indole-3-acetic acid in Arabidopsis. Plant Physiol 1998, 118:285-296. The authors fed Arabidopsis seedlings low levels of labeled IAA and followed its metabolism using MS. Oxidation was most prevalent at low IAA concentrations and formation of conjugates with Asp and Glu was observed at higher IAA concentrations. The authors also show that the IAA-Asp becomes oxidized, indicating that this conjugate can be an intermediate in the irreversible inactivation of IAA in Arabidopsis, as it is in other plants.

The superroot2 mutant contains elevated levels of free IAA and displays phenotypes that reflect this increase. The decrease of conjugated IAA in this mutant suggests that it is defective in IAA inactivation.

Local applications of an auxin transport inhibitor at the root-shoot junction prevented formation of lateral roots without affecting root elongation, and this inhibition was reversed after application of IAA. These results suggest that IAA from the shoot is required for lateral root induction.

The pin1 mutant, which has a pin-formed inflorescence and defects in embryo symmetry, was previously shown to be defective in polar auxin transport. Here the PIN1 gene was isolated by transposon tagging and shown to be expressed in all organs of the plant. The PIN1 protein was immunolocalized to the basal end of elongated xylem cells in stems, consistent with its proposed role as an auxin efflux carrier.

The eir1 mutant, which was previously isolated based on ethylene insensitivity in the root, has agravitropic roots and is allelic with agr1, pin2 and wav6-52. The EIR1 gene was cloned by transposon tagging [58••], positional cloning [59••,60•], and homology to PIN1 [61••], and is expressed in roots [58••,59••,60•,61••]. Double mutant analysis indicates that eir1 roots have reduced sensitivity to endogenous auxin [58••]. EIR1 expressed in yeast increases resistance to fluorinated indolic compounds [58,59], consistent with its proposed role as a auxin efflux carrier.

Vertically grown agr1 roots grow into media containing IAA or NAA, but not media containing 2,4-D. Since 2,4-D diffuses out of cells whereas IAA and NAA are transported via an efflux carrier, this result suggests a specific defect in auxin efflux.
