About this Research Topic
Filamentous fungi impressively produce a large inventory of small bioactive molecules known as secondary metabolites. Secondary metabolites are often only made under certain environmental conditions and in response to particular stimuli, both biotic and abiotic. These environmental cues are recognized and transmitted within fungal cells resulting in the conditional expression of the genes and proteins involved in the biosynthesis of secondary metabolites. These biosynthetic pathways and the metabolites themselves can be confined to particular organelles within the cell allowing both for efficient biosynthesis and facilitated secretion of these small molecules.
This Research Topic will highlight current research on signal recognition, signal transduction, and regulation of metabolite expression. Also to be considered will be cellular compartmentalization of secondary metabolic pathways and secretion mechanisms by which metabolites are transported outside the cell.
We particularly welcome manuscripts that address:
• Signaling factors and signal recognition triggering secondary metabolite synthesis.
• Signal transduction within the cell leading to expression of genes for secondary metabolites.
• Genetic and epigenetic regulation of secondary metabolite biosynthesis.
• The significance of cellular localization of secondary metabolic pathways and their integration with primary metabolism.
• Secretion of secondary metabolites involving membrane-bound transporters and vesicular transport including extracellular vesicles.
