Fig. 1. Regulation of phloem development by SMXL4/5-JULGI module. Unstructured G-quadruplex of SMXL4/5 leads translation, and accumulation of SMXL4/5 proteins promotes phloem differentiation. Conversely, formation of G-quadruplex in SMXL4/5 by JULGI suppresses translation, and inhibits phloem differentiation independent of other peptide- or transcription factor-mediated regulation. Blue arrows indicate potential movement of JUL-SMXL4/5 complex in SE. CC, companion cell; SE, sieve element.
