Functional identification of the DHN melanin synthesis gene cluster and its role in UV-C tolerance in citrus postharvest pathogenic fungus Penicillium digitatum.

The filamentous fungus Penicillium digitatum brings out great losses in citrus fruits by causing citrus green mold disease during the postharvest period. Previously, we obtained a T-DNA insertion mutant N2130 of P. digitatum, which produced albino conidia.
