Abstract: The present invention provides polynucleotides and related polypeptides of the ZmARGOS gene family. The invention provides genomic sequence for the ZmARGOS genes. ZmARGOS is responsible for controlling plant growth, organ size and yield in crop plants.

Abstract: The present invention provides polynucleotides and related polypeptides (SEQ ID NO: 11 and 44) of the ZmARGOS (Auxin-Regulated Gene involved in Organ Size) gene family. The invention provides genomic sequence for the ZmARGOS genes. ZmARGOS is responsible for controlling plant growth, organ size and yield in crop plants. Transgenic plants expressing ZmARGOS show a positive impact on biomass accumulation and rate of maize plant growth, as well as an increase in organ size. These maize genes will find utility for enhancing agronomic traits in maize (and other crops).

Abstract: This invention relates to an isolated nucleic acid fragment encoding an auxin transport protein. The invention also relates to the construction of a chimeric gene encoding all or a substantial portion of the auxin transport protein, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the auxin transport protein in a transformed host cell. The present invention also relates to methods using the auxin transport protein in modulating root development, and in discovering compounds with potential herbicidal activity.
