Article Synopsis
- The balance between cell growth and differentiation in plants is influenced by gene regulatory networks and signal transduction pathways, particularly involving reactive oxygen species (ROS) and transcription factors (TFs).
- In the model organism Arabidopsis thaliana, the MADS-box transcription factor XAANTAL1 (XAL1) plays a crucial role in mediating the effects of hydrogen peroxide (H2O2) on primary root growth and stem cell identity.
- XAL1 enhances H2O2 levels in the root meristem by regulating stress response genes and is key to inhibiting primary root growth through its negative regulation of peroxidase and catalase activities, while also promoting columella stem cell differentiation.
