Dispatch. Gibberellin signaling: GRASs growing roots dispatch.
Gibberellins are important endogenous plant growth regulators. A new study has revealed an unexpected role for gibberellin-regulated transcription factors in promoting root growth; this depends on signaling from another plant hormone, auxin, suggesting that auxin promotes root growth by modulating the cellular response to gibberellins.
