Identification and Biosynthesis of DHN-melanin Related Pigments in the Pathogenic Fungi Monilinia laxa, M. fructicola, and M. fructigena.

ABSTRACT: Monilinia is the causal agent of brown rot in stone fruit. The three main species that cause this disease are Monilinia laxa, M. fructicola, and M. fructigena, and their infection capacity is influenced by environmental factors (i.e., light, temperature, and humidity). To tolerate stressful environmental conditions, fungi can produce secondary metabolites. Particularly, melanin-like pigments can contribute to survival in unfavorable conditions. In many fungi, this pigment is due to the accumulation of 1,8-dihydroxynaphthalene melanin (DHN). In this study, we have identified for the first time the genes involved in the DHN pathway in the three main Monilinia spp. and we have proved their capacity to synthetize melanin-like pigments, both in synthetic mediu
