The hormonal circuitry controlling development in plants can be studied and re-programmed with hormone activated Cas9-based repressors.

The first global analysis of the effects of the transcription factor p53 on RNA synthesis illuminates several novels aspects of the molecular mechanism of action of this potent tumor suppressor.

A novel B12 containing photoreceptor is synthesized as two different isoforms that interact with the same transcription factor, with one isoform directing activation and the other promoting repression of photosystem synthesis.

Light absorption by the algal transcription factor Aureochrome 1a causes dimerization at the light-oxygen-voltage (LOV) sensing domain, which has implications for the design of synthetic photoreceptors for optogenetics.

The life cycle and morphology of the sea squirt Ciona intestinalis shed light on vertebrate evolution.

The mechanisms by which a retrotransposon called LINE-1 duplicates itself and spreads through the human genome are becoming clearer.
