How light and epigenetics cooperate to regulate plant growth
A research team led by Prof. Cao Xiaofeng at the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences (CAS) has uncovered the cooperative roles of photoreceptors, epigenetic modifiers, and transcription factors in regulating light-responsive genes in plants.
Repressed but ready to go: How bivalency holds developmental genes in a poised state for expression
As well as being essential in the precise packaging of DNA into the space of the nucleus, histone proteins are also the site of modifications, chemical additions referred to as epigenetic marks, that control whether a gene is silenced or expressed.
Strawberry ripening revealed: Key histone modifications uncovered
Fruit ripening is a tightly coordinated process driven by both hormonal and environmental factors, yet the epigenetic mechanisms controlling this process remain unclear.
