Pathogenic fungi are the main causes of diseases in forest plants, which determine losses to the forest, ornamental and landscape heritage and to the wood and nursery industries. These fungi are able to produce phytotoxins (i.e. secondary bioactive metabolites), which are involved in plant-pathogen interaction inducing disease symptoms. The discovery of new bioactive compounds is becoming a priority thanks to their wide-ranging applications, such as antibiotics, antivirals, chemotherapeutic agents and biopesticides with a low toxicity and eco-friendly. Many metabolites were previously isolated from pathogenic fungi of forest plants and they belong to different classes of naturally occurring compounds includings coumarins and isocoumarins, furopyrans, nonenolides, pyrones, terpenes, and some others.1 Among them, sphaeropsidin A (Fig. 1) was isolated from different fungi belonging to Diplodia species and showed some interesting activities such as phytotoxic, antifungal, antibacterial, anticancer, mosquito biting deterrent, larvicidal. In this communication the isolation and the chemical and biological characterization of phytotoxins produced by other pathogenic fungi of forest plants will be illustrated as well as the role of these toxins in the symptoms inducing.

Abstract
Pathogenic fungi are the main causes of diseases in forest plants, which determine losses to the forest, ornamental and landscape heritage and to the wood and nursery industries. These fungi are able to produce phytotoxins (i.e. secondary bioactive metabolites), which are involved in plant-pathogen interaction inducing disease symptoms. The discovery of new bioactive compounds is becoming a priority thanks to their wide-ranging applications, such as antibiotics, antivirals, chemotherapeutic agents and biopesticides with a low toxicity and eco-friendly. Many metabolites were previously isolated from pathogenic fungi of forest plants and they belong to different classes of naturally occurring compounds includings coumarins and isocoumarins, furopyrans, nonenolides, pyrones, terpenes, and some others.1 Among them, sphaeropsidin A (Fig. 1) was isolated from different fungi belonging to Diplodia species and showed some interesting activities such as phytotoxic, antifungal, antibacterial, anticancer, mosquito biting deterrent, larvicidal. In this communication the isolation and the chemical and biological characterization of phytotoxins produced by other pathogenic fungi of forest plants will be illustrated as well as the role of these toxins in the symptoms inducing.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
