AuxinTogether

AuxinTogether is a term used in plant biology to describe a conceptual framework for the coordinated action of the plant hormone auxin across multiple cells and tissues. It emphasizes synchronized responses to auxin gradients rather than isolated, cell-autonomous effects, and it is used to interpret how local auxin production, polar transport, and receptor signaling integrate to shape organ initiation and tropic growth.

The concept encompasses mechanisms such as gradient formation, PIN-FORMED transporters, canalization of auxin flow, and cross-talk with other hormones. In practice, AuxinTogether informs both computational modeling of tissue-wide growth and experimental designs that monitor coordinated responses across tissues. Researchers commonly employ live reporters like DR5 and DII-VENUS to visualize how auxin signals propagate and synchronize in developing organs.

Origins and usage of the term are not standardized. AuxinTogether has appeared in a subset of reviews, seminars, and modeling studies as a descriptive label rather than a formal nomenclature, which means its exact definition can vary between authors. Nevertheless, it serves as a shorthand for discussions about systems-level auxin dynamics rather than single-cell effects.

Applications and implications include testing whether perturbations in one tissue influence distant regions, using approaches such as grafting, localized hormone application, or tissue-specific gene perturbations. The term encourages integrative thinking about how auxin transport, signaling, and cross-talk coordinate growth responses across the plant body.
