Choline- and acetylcholine-induced changes in the morphology of Fusarium graminearum: evidence for the involvement of the choline transport system and acetylcholinesterase

Article Abstract:

Fusarium graminearum choline and mutant strains increase hyphal extension and decreases hyphal branching but nim mutants resistant to nitrogen mustard have a reduced morphological response to choline. These mutants cannot grow if choline is the only carbon source as they are unable to transport choline but there is no change in their response to betaine. Choline and its analogues are transported by permeases and act inside the hyphae while betaine transport is independent of choline transport. The morphological effects of choline do not involve external receptor-binding.

Transcriptome analysis of recombinant protein secretion by Aspergillus nidulans and the unfolded-protein response in vivo1

Article Abstract:

The effects of recombinant protein secretion on gene expression levels in Aspergillus nidulans are reported using expressed sequence tag microarrays. The impact of overexpressing a secreted recombinant protein more closely resembles the unfolded-protein response in vivo.

Development and application of an assay for uranyl complexation by fungal metabolites, including siderophores

Article Abstract:

Research has been conducted on fungal metabolites. The ability of these metabolites to complex actinides has been investigated via the use of the assay based on the chrome azurol S assay for siderophores.
