The agmatinase MrAGM1 is required for Metarhizium robertsii virulence by modulating putrescine-associated appressorium development.
BACKGROUND Fungal polyamine metabolism plays an integral role in cellular development and host-pathogen interactions. However, the biological functions of agmatinase, a key enzyme that hydrolyzes agmatine to putrescine and urea, remain poorly characterized in entomopathogenic fungi. RESULTS In this study, we characte...
