How are plant stem cells with DNA damage processed?

The protein KRP6 accumulates near stem cells and promotes cell death in damaged cells, thereby removing them.

Which plant did the research group use?

The research was conducted using Arabidopsis thaliana, a plant in the mustard family.

What role does the SOG1 protein play?

SOG1 protein is activated in response to DNA damage and controls the expression of a cluster of DNA damage response genes, including KRP6.

What potential applications could this research have?

This research could be applied to developing crops that are more resilient to environmental stress and to technologies that stabilize plant growth.

Where was the result of this study published?

The results were published online in the international academic journal 'The Plant Journal' on June 4, 2026.
