  bibo_abstract:
  - Plants must continually balance growth with arrest, especially under stress. Auxin
    signaling acts as a central regulatory hub in this process, yet the mechanisms
    that dynamically tune early auxin signalling in real time remain unknown. Here,
    we used the light-gated, Ca2+-permeable Channelrhodopsin 2 variant XXM2.0 to optogenetically
    impose defined Ca2+ signatures on Arabidopsis root cells. Repetitive light activation
    triggered cytosolic Ca2+ signals that in turn suppressed auxin-induced membrane
    depolarization and Ca2+ transients. Moreover, prolonged optogenetic Ca2+ stimulation
    affects auxin-responsive transcriptional reprogramming. As phenotypic output,
    reversible inhibition of root growth by suppressing cell division and elongation
    was observed. We further identify a candidate CaM7–CNGC14 module that likely mediates
    Ca2+-dependent gating of early auxin signalling. Our study thus introduces a synthetic
    biology approach to decompose calcium–auxin crosstalk in plant cells, and demonstrates
    that optogenetically imposed cytosolic Ca2+ signals act as dynamic regulators
    of auxin susceptibility in roots.@eng
