Mechanizmy obronne roślin drzewiastych uruchamiane w odpowiedzi na atak patogenów

Abstract

This paper presents a comprehensive study on the mechanisms of tree responses to pathogens. We describe natural resistance concerning the presence of different types of barriers protecting plants from invasion and also give them strength after a pathogen attack. We put emphasis on induced resistance functioning both locally and systemically and involvement of phytohormones signaling networks. Systemic acquired resistance (SAR) involved the action of salicylic acid and H202 and accumulation of pathogenesis-related proteins. In turn, jasmonates and ethylene are signaling molecules in the induced resistance (SIR). All these substances play a crucial role in the forest management and can be applied in the tree protection strategies based on the natural and synthetic active compounds.
