Klaudia Rząd, Aleksandra Nucia, Katarzyna Szwaczko, Arkadiusz Matwijczuk, Sylwia Okoń
TL;DR
This study explores coumarin compounds as eco-friendly fungicides against cereal pathogens like powdery mildew and rust.
Contribution
The study evaluates the antifungal potential of coumarin derivatives against biotrophic cereal pathogens in a lab setting.
Findings
Coumarin derivatives showed varying effectiveness in inhibiting biotrophic fungal growth.
Two compounds reduced pathogen structures, indicating potential to limit infection spread.
Abstract
Parasitism is a harmful relationship between microorganisms and their host. Biotrophic fungi, such as powdery mildew and rusts, are obligate parasites that extract nutrients from living plant cells using specialized structures like haustoria and appressoria. These pathogens weaken plant defenses by inhibiting enzyme secretion, making them particularly dangerous. Blumeria graminis, causing powdery mildew, affects all cereals and forms a white coating. Pucciniales, or rusts, represent the largest group of biotrophs, with complex life cycles involving up to five spore stages, complicating their identification. Resistance to chemical pesticides and environmental concerns have driven interest in alternative, safer, plant protection solutions. One promising group is coumarin and its derivatives, known for antifungal properties and biodegradability. Our study aimed to test the effectiveness of…
