INT – Iron Boosts Rice Immune System

01 March 2023 – ISAAA Crop Biotech Update

Researchers from the Centre for Research in Agricultural Genomics (CRAG) have successfully shown that iron treatment helps increase the resistance against rice blast fungus and activate the plant’s immune response against the pathogen.

A study published in the Rice journal led by Blanca San Segundo, a researcher at CRAG, reveals that exposing rice plants to moderately high levels of iron increases resistance to infection by the pathogenic fungus Magnaporthe oryzae, the agent causing rice blast, the most common disease in rice responsible for large production losses worldwide.
