The plant-specific GAI-RGA-and-SCR (GRAS) family proteins play critical roles in plant development and signaling. Two GRAS proteins, SHORT-ROOT (SHR) and SCARECROW (SCR), cooperatively direct asymmetric cell division and the patterning of root cell types by transcriptional control in conjunction with BIRD/INDETERMINATE DOMAIN (IDD) transcription factors, although precise details of these specific interactions and actions remain unknown. Here, we present the crystal structures of the SHR-SCR binary and JKD/IDD10-SHR-SCR ternary complexes. Each GRAS domain comprises one α/β core subdomain with an α-helical cap that mediates hetero-dimerization by forming an intermolecular helix bundle. The α/β core subdomain of SHR forms the BIRD-binding groove, which specifically recognizes the zinc fingers of JKD. We identified a conserved SHR-binding motif (SHBM) in 13 BIRD/IDD transcription factors. Our results establish a structural basis for GRAS-GRAS and GRAS-BIRD interactions and provide valuable clues towards our understanding of these regulators involved in plant-specific signaling networks.
