Identification of Slime Mold Metabolites That Confer Protection to Commercial Crops against Root-Knot Nematodes Open
Root-knot nematodes are major pests of various crops, coexisting in the soil with amoebae, such as the cellular slime mold Dictyostelium discoideum. Prior studies have indicated that nematodes prey on Dictyostelium, prompting investigation…
