SDG2 regulates Arabidopsis inflorescence architecture through SWR1-ERECTA signaling pathway

Summary: Inflorescence architecture is diverse in flowering plants, and two determinants of inflorescence architecture are the inflorescence meristem and pedicel length. Although the ERECTA (ER) signaling pathway, in coordination with the SWR1 chromatin remodeling complex, regulates inflorescence ar...
