  text: Roots are highly plastic organs enabling plants to adapt to a changing below‐ground
    environment. In addition to abiotic factors like nutrients or mechanical resistance,
    plant roots also respond to temperature variation. Below the heat stress threshold,
    Arabidopsis thaliana seedlings react to elevated temperature by promoting primary
    root growth, possibly to reach deeper soil regions with potentially better water
    saturation. While above‐ground thermomorphogenesis is enabled by thermo‐sensitive
    cell elongation, it was unknown how temperature modulates root growth. We here
    show that roots are able to sense and respond to elevated temperature independently
    of shoot‐derived signals. This response is mediated by a yet unknown root thermosensor
    that employs auxin as a messenger to relay temperature signals to the cell cycle.
    Growth promotion is achieved primarily by increasing cell division rates in the
    root apical meristem, depending on de novo local auxin biosynthesis and temperature‐sensitive
    organization of the polar auxin transport system. Hence, the primary cellular
    target of elevated ambient temperature differs fundamentally between root and
    shoot tissues, while the messenger auxin remains the same.
