Breaking symmetry by asymmetric cell divisions is essential for establishing different cell identities in multi-cellular development. Cell-cell signaling by receptor kinase/MAP kinase signaling pathways seems to be a reoccurring mechanism in polarizing plant cells and establishing different cell identities in the daughter cell of asymmetric cell divisions. 
We are using the early plant embryo as system to study initial events in cell polarization by the ERECTA-YODA signaling pathway – a prototype receptor kinase/MAP kinase signaling pathway. 
Embryogenesis resembles a linear system of developmental progression with successive asymmetric cell divisions that produce the primary tissue types of the plant seedling and establish the stem cell niches of the shoot and root. By comparing the function of the ERECTA-YODA pathway in the embryo with its role in planar patterning of the leaf epidermis, we identified principal functions of a core pathway and context-specific modifications. 
We present new data on the impact of polar YODA activation on early embryonic patterning and shed light on the mechanism and evolution of distinct modes of YDA activation in the zygote on a molecular and structural level. We furthermore discuss possible benefits of different modes of YDA activation and their distinct parent-of-origin effects.
