Phytotoxin [360p]

: Used in plant-plant interactions to inhibit the growth of neighboring competitors.

Phytotoxins and their involvement in plant diseases. Introduction

: 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. phytotoxin

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

: Affect a broad range of plant species. : Used in plant-plant interactions to inhibit the

Phytotoxins can be classified based on their source and how they target plants:

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 Host-Specific (HST) : Affect only specific plant genotypes

Humans and animals can be exposed to phytotoxins through direct physical contact or by consuming contaminated food and water.
