Transcription factor WRKY53 transcriptionally activates sensitive to proton rhizotoxicity 1 to promote C-repeat binding factors 1 and 3 mediated chilling tolerance in apple.
Chilling stress limits apple (Malus domestica) growth and productivity, particularly in spring, when chilling events can severely impair bud break and early shoot development. However, the regulatory mechanisms underlying chilling adaptation in apple remain incompletely understood. Here, we identified the C2H2 zinc-fin...
