<i>AtAUEs</i>, a Small Family of ABA Up-Regulated EAR Motif-Containing Proteins Regulate ABA Responses in Arabidopsis.

ABSTRACT: The abscisic acid (ABA) signaling pathway is crucial for regulating downstream ABA-responsive genes, which influence plant responses to ABA and abiotic stresses. However, many ABA-responsive genes remain poorly characterized. This study reports on the identification and characterization of ABA up-regulated EAR motif-containing proteins (AtAUEs), a novel family of EAR motif-containing proteins in Arabidopsis thaliana. From a previous transcriptome dataset, AtAUEs were identified as a family of unknown-function ABA-response genes with only five members, and the up-regulation of AtAUEs by ABA was further confirmed by quantitative RT-PCR (qRT PCR). All AtAUEs contain at least one LxLxL EAR motif and can repress reporter gene expression in Arabidopsis protopla
