Briefings

Researchers identified that plants use ferroptosis, a form of cell death driven by iron-dependent oxidative stress, to execute the hypersensitive response against pathogens. This mechanism was first described in 1915 but its molecular details remained unclear for over a century. The study highlights a dual role where ferroptosis limits pathogen spread while potentially aiding plant defense.

Key points

• The hypersensitive response (HR) is an immune defense mechanism in plants first described in 1915.
• Ferroptosis, an iron-dependent oxidative cell death, serves as the molecular mechanism underlying HR.

Context

This research clarifies a long-standing mystery in plant immunity by linking a specific type of programmed cell death to the hypersensitive response, which was historically described in 1915 but its molecular basis remained poorly understood for more than a century.

Limitations

The evidence is limited to a single sentence describing the historical context of the hypersensitive response. It does not provide specific dates, locations, or quantitative data regarding the discovery of ferroptosis or its role in plant immunity.
