Corn spots: Study finds important genes in defense response

12 septiembre 2014

When corn plants come under attack from a pathogen, they sometimes respond by killing their own cells near the site of the attack, committing «cell suicide» to thwart further damage from the attacker. This cell sacrifice can cause very small, often microscopic, spots or lesions on the plant. Researchers have now scoured the corn genome to find candidate genes that control this important defense response.
