Suspensor plays an important role in embryogenesis, especially in establishing the apical‐basal polarity. Loss of function of RPL18aB resulted in suspensor cell proliferation rather than undergoing programmed cell death in the wildtype. In this issue, Xie et al. (pp. 266–269) show that RPL18aB is required for the maintenance of suspensor identity. This work provides a clue to understanding how the suspensor cells maintain its identity during early embryogenesis.
