Abstract
Pathogenic fungi are influenced by many biotic and abiotic factors. Among them, light is a
source of information for fungi and also a stress factor that triggers multiple biological responses,
including the activation of secondary metabolites, such as the production of melanin pigments. In
this study, we analyzed the melanin-like production in in vitro conditions, as well as the expression
of all biosynthetic and regulatory genes of the DHN–melanin pathway in the three main Monilinia
species upon exposure to light conditions (white, black, blue, red, and far-red wavelengths). On
the other hand, we analyzed, for the first time, the metabolism related to ROS in M. fructicola,
through the production of hydrogen peroxide (H2O2) and the expression of stress-related genes
under different light conditions. In general, the results indicated a clear importance of black light on
melanin production and expression in M. laxa and M. fructicola, but not in M. fructigena. Regarding
ROS-related metabolism in M. fructicola, blue light highlighted by inhibiting the expression of many
antioxidant genes. Overall, it represents a global description of the effect of light on the regulation of
two important secondary mechanisms, essential for the adaptation of the fungus to the environment
and its survival.
