In Arabidopsis, a cell surface receptor complex containing SUB and QKY play the central role in intercellular communication and tissue morphogenesis. But it is still unclear how QKY stabilizes SUB at the cell surface, and what the architecture of SUB/QKY complex is in vivo. Here, we focused on the vivo structure-function analysis of QKY and its interaction with SUB using a mix of genetics, cell biology, and fluorescence microspectrometry. Our results provide novel molecular insight into the predicted heteromeric complex formed by the physical interaction of QKY and SUB.
