According to a 2024 study, researchers have identified 23 distinct chitinase genes within the watermelon genome, confirming the presence of this defense-related enzyme in the plant. This discovery clarifies the complex immune system of watermelons and explains how they naturally protect themselves from fungal threats.

Tomatoes, a staple in many kitchens, are often confused with other chitin-containing foods, such as mushrooms. However, the truth is that tomatoes, and all other plants, do not produce or contain chitin. The structure that gives plants their rigidity is a different polysaccharide called cellulose.

Over 9,000 species of marine macroalgae, or seaweeds, are known to exist, many producing bioactive compounds with antimicrobial properties. This raises the question: is seaweed a fungicide, or does it offer a more nuanced, eco-friendly approach to plant defense against pathogens?
