Auxin has a central role in the establishment and elaboration of pattern in root meristems. Regulation of root development by auxin begins early in embryogenesis, perhaps even as early as the establishment of polarity in the zygote, and persists throughout the lifetime of a root. Auxin-regulated development depends on a balance of synthesis/import and metabolism/export/sequestration. The overall result of these processes is to establish a state of auxin homeostasis which we hypothesize is required for normal root meristem patterning and development.
