Transcriptional control of ABI5 expression via the group VII ERFs7 and posttranslational S-nitrosylation of ABI5 protein are included. Dormant and dry seeds accumulate high levels of the ABA-induced ABI5 growth reppressor. On seed imbibition, a burst of NO is early produced to degrade group VII ERFs via the N-end rule pathway of targeted proteolysis (PRT6)25,26 and induces ABI5 S-nitrosylation promoting the interaction with CUL4-based and KEG E3 ligases. Consequently, ABI5 is rapidly degraded by the proteasome during seed germination.
