Phytoalexins

Phytoalexins are natural compounds produced by plants as part of their defense system to fend off pathogens. When plants encounter bacteria, fungi, or viruses, they respond by synthesizing these antimicrobial substances, which help to contain and prevent the spread of infection. Each plant species creates specific phytoalexins, such as camalexin in Arabidopsis or resveratrol in grapes, each tailored to combat distinct threats. By studying phytoalexins, scientists aim to enhance plant resilience through breeding or genetic engineering, boosting natural disease resistance. This focus on phytoalexins is crucial for agriculture, where healthier, more robust crops can reduce reliance on chemical pesticides.
