Co-repressors are essential for regulating transcription in all living organisms. An interdisciplinary team has elucidated the structure of a plant co-repressor named TOPLESS. This work shows that this protein is composed of domains identical to those of other co-repressors but with different properties, illustrating how evolution recovers protein domains to create new functions. This study, which also paves the way for reasoned manipulations of this key protein for adapting plants to the environment, was published on July 11, 2017 in the journal
