Caption
Genetic material is packaged around proteins called histones (purple) and folded into larger chromosome structures (blue) to both organize DNA within the cell’s nucleus and influence how it is accessed and maintained. Using the model plant Arabidopsis thaliana, Salk Institute scientists found that, when DNA damage is detected in vulnerable stem cell populations, the levels of the protein YAF9B (pink) increase. YAF9B works alongside other repair factors and histone modifying proteins (light purple, green, light blue) to support accurate DNA repair and maintain genome stability.
