This research identifies ABI3 target genes in Arabidopsis thaliana, suggesting its crucial role in seed maturation.

The aim is to identify and understand the role of ABI3 target genes in seed development in Arabidopsis thaliana.
Conducted genome-wide chromatin immunoprecipitation (ChIP-chip) to identify ABI3 target genes.
Performed transcriptome analysis and quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) for validation.
Executed a transient promoter activation assay to study gene expression regulation.
Identified 98 ABI3 target genes that require abscisic acid for activation during seed maturation.
Promoter analyses showed enrichment for G-box-like and RY-like elements associated with ABI3 targets.
Some ABI3 target genes are also regulated by other transcription factors like FUS3 and LEC2.

Mönke et al. (2012) studied this question.
