Septum formation in Aspergillus nidulans.
Filamentous fungi form multicellular hyphae that are partitioned by septa. In A. nidulans, septum formation requires the assembly of a septal band following the completion of mitosis. Recent observations show that this band is a dynamic structure composed of actin, a septin and a formin. In addition, assembly is dependent upon a conserved protein kinase cascade that regulates mitotic exit and s...
متن کاملRegulation of septum formation in Aspergillus nidulans by a DNA damage checkpoint pathway.
In Aspergillus nidulans, germinating conidia undergo multiple rounds of nuclear division before the formation of the first septum. Previous characterization of temperature-sensitive sepB and sepJ mutations showed that although they block septation, they also cause moderate defects in chromosomal DNA metabolism. Results presented here demonstrate that a variety of other perturbations of chromoso...
متن کاملFunctional diversity of chitin synthases of Aspergillus nidulans in hyphal growth, conidiophore development and septum formation.
Fungal chitin synthases are classified into seven classes. Recent advances in genome sequence analyses have revealed that there are more than seven chitin synthase-encoding genes in the genome of filamentous ascomycete fungi. To clarify the functional differences among these genes in the morphogenesis and hyphal tip growth, we have cloned six chitin synthase-encoding genes from Aspergillus nidu...
متن کاملRegulation of septum formation by the Bud3-Rho4 GTPase module in Aspergillus nidulans.
The ability of fungi to generate polarized cells with a variety of shapes likely reflects precise temporal and spatial control over the formation of polarity axes. The bud site selection system of Saccharomyces cerevisiae represents the best-understood example of such a morphogenetic regulatory system. However, the extent to which this system is conserved in the highly polarized filamentous fun...
