text: Plants, like other multicellular organisms, survive through a delicate balance
between growth and defense against pathogens. Salicylic acid (SA) is a major defense
signal in plants, and the perception mechanism as well as downstream signaling
activating the immune response are known. Here, we identify a parallel SA signaling
that mediates growth attenuation. SA directly binds to A subunits of protein phosphatase
2A (PP2A), inhibiting activity of this complex. Among PP2A targets, the PIN2 auxin
transporter is hyperphosphorylated in response to SA, leading to changed activity
of this important growth regulator. Accordingly, auxin transport and auxin-mediated
root development, including growth, gravitropic response, and lateral root organogenesis,
are inhibited. This study reveals how SA, besides activating immunity, concomitantly
attenuates growth through crosstalk with the auxin distribution network. Further
analysis of this dual role of SA and characterization of additional SA-regulated
PP2A targets will provide further insights into mechanisms maintaining a balance
between growth and defense.
