Phytotoxin Access

Phytotoxins and their involvement in plant diseases. Introduction

: They belong to diverse chemical families, including alkaloids, terpenes, polyketides, peptides, and cyanogenic glycosides. Impact on Humans and Animals phytotoxin

Phytotoxins are bioactive, poisonous substances produced naturally by plants or plant pathogens (such as bacteria and fungi). These complex compounds primarily serve as defensive agents against predators like insects and pests, or as tools for pathogens to invade and infect host plants. Types and Origins Phytotoxins and their involvement in plant diseases

Phytotoxins can be classified based on their source and how they target plants: often resulting in symptoms like wilting

: Secreted by fungi or bacteria to damage plant tissue, often resulting in symptoms like wilting, chlorosis (yellowing), or necrosis (tissue death). Host-Specific (HST) : Affect only specific plant genotypes.
