After double fertilization, zygotic activation occurs that initiates a new life cycle, followed by cell divisions, cell differentiation and organogenesis. During post-embryonic development, stem cells located in shoot apical meristem (SAM) and root apical meristem (RAM) allow plants to continuously generate new tissues and organs. Therefore, understanding the role of zygote activation and stem cell homeostasis is a long-standing interest to scientists.
