New Online! Mechanisms of auxin action in plant growth and development
Mechanisms of auxin action in plant growth and development
Nature Reviews Molecular Cell Biology, Published online: 19 May 2025; doi:10.1038/s41580-025-00851-2The phytohormone auxin coordinates plant growth by forming local maxima and gradients through cell-to-cell transport and metabolic control. Recent research has identified novel signalling mechanisms involving extracellular auxin perception and auxin-mediated cyclic AMP production.

Perspectives on a co-option of a familiar signaling pathway for embryo patterning, where phosphorylation of SCREAM by MPK3/6 triggers different outcomes. But..Symmetric Cell Division is EXCITING and essential for generating a mirror-symmetric Guard Cell pair😘🌱.
