Putative cell wall integrity sensor proteins in Aspergillus nidulans
The cell wall integrity (CWI) signal transduction pathway, which has been well-studied in the yeast Saccharomyces cerevisiae, plays an important role in the regulation of cell wall biogenesis. Recently, we characterized the CWI stress sensor orthologs WscA and WscB in the filamentous fungus Aspergillus nidulans. Disruption of the wscA and wscB genes causes a change in the transcriptional levels...
متن کاملMolecular characterization of protein O-mannosyltransferase and its involvement in cell-wall synthesis in Aspergillus nidulans.
Protein O-glycosylation is essential for protein modification and plays important roles in eukaryotic cells. O-Mannosylation of proteins occurs in the filamentous fungus Aspergillus. The structure and function of the pmtA gene, encoding protein O-d-mannosyltransferase, which is responsible for the initial O-mannosylation reaction in Aspergillus nidulans, was characterized. Disruption of the pmt...
متن کاملRole of LAMMER Kinase in Cell Wall Biogenesis during Vegetative Growth of Aspergillus nidulans
Depending on the acquisition of developmental competence, the expression of genes for β-1,3-glucan synthase and chitin synthase was affected in different ways by Aspergillus nidulans LAMMER kinase. LAMMER kinase deletion, ΔlkhA, led to decrease in β-1,3-glucan, but increase in chitin content. The ΔlkhA strain was also resistant to nikkomycin Z.
متن کاملbasA regulates cell wall organization and asexual/sexual sporulation ratio in Aspergillus nidulans.
Sphingolipid C4 hydroxylase catalyzes the conversion of dihydrosphingosine to phytosphingosine. In Saccharomyces cerevisiae, Sur2 is essential for sphingolipid C4 hydroxylation activity but not essential for normal growth. Here we demonstrate that the Aspergillus nidulans Sur2 homolog BasA is also required for phytosphingosine biosynthesis but is also essential for viability. We previously repo...
متن کاملAspergillus nidulans RhoA is involved in polar growth, branching, and cell wall synthesis.
Growth of the filamentous fungus Aspergillus nidulans begins when the conidium breaks dormancy and grows isotropically. Eventually a germ tube emerges and the axis of growth remains fixed in the primary hypha while new growth axes are established basally to form secondary germ tubes and lateral branches. Rho1 is a Rho family GTPase that has been shown to be involved in polarity establishment an...
