Polarity in filamentous fungi: establishment, maintenance and new axes.
Germ tube emergence in filamentous fungi appears to be similar to bud emergence in yeast. Several key proteins (e.g. Cdc42, septins, Bni1 formin, Rho1 and Rho3) play common roles in polarity establishment and early polarity maintenance in both processes. Although germ tube extension, which can be thought of as extreme polarity maintenance, uses some of the same genes, they are likely to be regu...
متن کاملAspergillus nidulans swo mutants show defects in polarity establishment, polarity maintenance and hyphal morphogenesis.
When the spores of filamentous fungi break dormancy, they grow isotropically, adding cell wall material uniformly in every direction. Later they switch to polarized growth, with new material added to the tip of an emerging germ tube. To identify genes involved in the synthesis and localization of cell wall material in filamentous fungi, we screened a collection of temperature-sensitive Aspergil...
متن کاملLong Astral Microtubules and RACK-1 Stabilize Polarity Domains during Maintenance Phase in Caenorhabditis elegans Embryos
Cell polarity is a very well conserved process important for cell differentiation, cell migration, and embryonic development. After the establishment of distinct cortical domains, polarity cues have to be stabilized and maintained within a fluid and dynamic membrane to achieve proper cell asymmetry. Microtubules have long been thought to deliver the signals required to polarize a cell. While pr...
متن کاملCa2+ influx and phosphoinositide signalling are essential for the establishment and maintenance of cell polarity in monospores from the red alga Porphyra yezoensis
The asymmetrical distribution of F-actin directed by cell polarity has been observed during the migration of monospores from the red alga Porphyra yezoensis. The significance of Ca2+ influx and phosphoinositide signalling during the formation of cell polarity in migrating monospores was analysed pharmacologically. The results indicate that the inhibition of the establishment of cell polarity, a...
