The working model for SlREM1 in regulating tomato fruit ripening and cell death. SlREM1 interacted with the key enzymes (namely SlSAM1, SlACS2 and SlACO1) involved in ethylene biosynthesis, to modulate ethylene production. SlREM1 also induced programmed cell death (PCD) by activating reaction oxygen species (ROS) production and up-regulating abundance of CYSTEINERICH AND TRANSMEMBRANE DOMAIN-CONTAINING PROTEIN A-LIKE (CRTD), BLUE COPPER PROTEIN-LIKE (BCPL), NUCLEAR CAPBINDING PROTEIN SUBUNIT 2 (NCBP2), and RBOHB
