Transcription activator that plays a role in the promotion of seed germination by both negatively and positively regulating the abscisic acid (ABA) and phytochrome A (phyA) transduction pathways, respectively. A number of isoforms are produced. According to EST sequences. Barely detectable in stems, leaves, siliques, and dry seeds, but was present at considerable levels in roots, flowers and imbibited seeds. Down-regulated during germination. During seed imbibition. The NET domain could serve as an interface to localize different proteins or complexes to chromatin. Impaired cotyledon greening during germination. Seeds are deficient in the phytochrome A (phyA)-mediated very-low-fluence response of germination. Mature plants appear normal.
