Article Synopsis
- Melanin in the fungal pathogen Mycosphaerella fijiensis plays a key role in its virulence by generating reactive singlet molecular oxygen (O2 (1Δg)), which can cause cell death and disrupt plant defenses.
- Research utilized various analytical techniques to identify the specific type of melanin present, confirming it as 1,8-dihydroxynaphthalene (DHN)-melanin, and demonstrated that irradiating this melanin with a laser produces singlet oxygen.
- Observations from banana leaves infected with black Sigatoka disease showed a correlation between melanin presence and disease severity, indicating that DHN-melanin may contribute to the pathogen's destructive effects on banana leaf tissues through reactive oxygen
