Abstract:
Storage compounds like oil and storage proteins accumulate both in the endosperm and in the embryo of Arabidopsis seeds. The MYB118 transcription factor is specifically expressed in the endosperm and represses storage compound synthesis in this tissue, thus contributing to establishment of the embryo as the main deposition site for reserves in the seed.
