    Area of Science:

    • Biochemistry
    • Molecular Biology
    • Plant Science

    Context:

    • Reviews existing literature on auxin structure-activity relationships.
    • Focuses on aryl-, arylalkane-, and aryloxyalkanoic acids compared to 3-indolylacetic acid.
    • Explores the bifunctional binding hypothesis for auxin-receptor interaction.

    Purpose:

    • To compare the structure of active auxins with inactive analogs.
    • To construct a model of the auxin receptor's intrinsic binding site.
    • To propose geometric parameters and binding site arrangements for the auxin receptor.

    Summary:

    • A literary review correlates the structure and auxin activity of various carboxylic acids.
    • A bifunctional binding hypothesis facilitated the construction of an auxin receptor model.
    • The model details the receptor's geometric parameters and specific binding site arrangements.
    • Evidence suggests auxin absorption induces conformational changes in the receptor, a primary functional effect.

    Impact:

    • Provides a structural model for the auxin receptor.
    • Elucidates the mechanism of auxin binding and its functional consequences.
    • Offers insights into the molecular basis of auxin action in plants.
