A disulfide bond sculpts the CTNIP4 phytocytokine fold for recognition by the receptor kinase HSL3
This work shows how the LRR-RK HSL3/NUT specifically recognizes the folded, disulfide-stabilized CTNIP4/SCREW2 phytocytokine in Arabidopsis, revealing an unexpected mechanism by which plants achieve highly specific cell-to-cell communication.
