Fungal growth depends on active transport of macromolecules along the actin and/or microtubule cytoskeleton. Thereby, molecular cargo such as proteins, lipids, and mRNAs is targeted to defined subcellular regions. Active transport and localisation of mRNAs mediate localised translation so that protein synthesis occurs where protein function is required. In Saccharomyces cerevisiae, actomyosin-dependent mRNA trafficking participates in polar growth, asymmetric cell division, targeting of membrane proteins and import of mitochondrial proteins. The best-understood example is transport of ASH1 mRNA to the distal pole of the incipient daughter cell. cis-acting RNA sequences are recognised by the RNA-binding protein She2p that is connected via the adaptor She3p to the molecular motor Myo4p. Local translation at the poles of daughter cells causes Ash1p to accumulate predominantly in nuclei of daughter cells, where this transcription factor inhibits mating-type switching. Recently, it was also shown that actomyosin-dependent ASH1 mRNA transport directs tip cell-specific gene expression in filaments of the human pathogen Candida albicans. Furthermore, in the plant pathogen Ustilago maydis microtubule-dependent shuttling of the RNA-binding protein Rrm4 is essential to determine the axis of polarity in infectious filaments. Thus, mRNA trafficking appears to be universally required for polar growth of fungi.
