The AP2/ERF Transcription Factor ERF56 Negatively Regulating Nitrate-Dependent Plant Growth in <i>Arabidopsis</i>.

ABSTRACT: ERF56, a member of the APETALA2/ETHYLENE-RESPONSIVE FACTOR (AP2/ERF) transcription factor (TF) family, was reported to be an early nitrate-responsive TF in Arabidopsis. But the function of ERF56 in nitrate signaling remains not entirely clear. This study aimed to investigate the role of ERF56 in nitrate-dependent plant growth and nitrate signaling. We confirmed with reverse transcription quantitative PCR (RT-qPCR) that the transcription of ERF56 is quickly induced by nitrate. ERF56 overexpressors displayed decreased nitrate-dependent plant growth, while erf56 mutants exhibited increased plant growth. Confocal imaging demonstrated that ERF56 is localized into nuclei. Assays with the glucuronidase (GUS) reporter showed that ERF56 is mainly exp
