The RNA world of fungal pathogens

Abstract

Fungal pathogens execute well-defined infection programs that are intensively regulated at the posttranscriptional level. RNA biology determines the precise timing and subcellular expression of the encoded proteins. This temporal coordination is especially vital for membrane trafficking in order to synchronize the intracellular organelle network. This includes vacuole maturation, intra- and extracellular vesicle (EV) transport, protein entry into mitochondria, peroxisomes, and the ER. Here, we explore the intimate link between membrane trafficking, organelle function, and the RNA world during fungal plant pathogenesis, with a specific emphasis on the corn smut Ustilago maydis.
