Organizing and summarizing search results for youPhytotoxins, also known as plant poisons, are biologically active chemical substances. They can be produced by plants themselves, by microorganisms, or through naturally occurring chemical reactions. These toxic substances have adverse effects on living organisms and can include small molecules, peptides, or proteins. Phytotoxins serve as defense compounds against herbivores, insects, or other plant species.4 Sources
