Summary Fruit crops are subject to precocious fruit abscission, during which the phytohormone ethylene (ET) acts as a major positive regulator. However, the molecular basis of ET‐induced fruit abscission remains poorly understood. Here, we show that two ETHYLENE INSENSITIVE 3‐like (EIL) homologs in...
