Arabidopsis WRKY2 transcription factor mediates seed germination and postgermination arrest of development by abscisic acid

摘要

BackgroundPlant WRKY DNA-binding transcription factors are key regulators in certain developmental programs. A number of studies have suggested that WRKY genes may mediate seed germination and postgermination growth. However, it is unclear whether WRKY genes mediate ABA-dependent seed germination and postgermination growth arrest.
