Abstract

Fusarium fujikuroi (teleomorph Gibberella fujikuroi) is a notorious rice pathogen and the causative agent of the bakanae (foolish seedling) disease. The symptoms of this disease, i.e., thin, chlorotic, and hyper-elongated rice internodes and often sterile grains, are due to the ability of this fungus to produce and secrete the phytohormones gibberellins (GAs). In addition to the GAs, F. fujikuroi produces a plethora of other secondary metabolites (SMs), including pigments but also potent mycotoxins. SMs are not essential for growth but may pose a selective advantage under certain environmental conditions, and as such are regulated by a complex gene regulatory network. The genes involved in the biosynthesis of individual SMs are physically linked in the fungal genome, thereby facilitating a coordinated and timely response when needed. Several of these regulatory components have been studied in F. fujikuroi. These include signal transduction pathways as well as narrow-domain and wide-domain transcriptional regulators. Another regulatory layer that has emerged as a key player in fungal SM gene regulation is chromatin structure. This chapter summarizes the current knowledge on SM biosynthesis in F. fujikuroi and the regulatory mechanisms that control their expression with a focus on chromatin structure.
