Analysis of acetate non-utilizing (acu) mutants in Aspergillus nidulans.
Genetic analysis of 119 acetate non-utilizing (acu) mutants in Aspergillus nidulans revealed ten new loci affecting acetate metabolism in addition to the three previously recognized on the basis ofExpand

It is suggested that the Leloir pathway operates at pH 4.0–6.5 but some other route at Ph 7.5, and two systems of galactose utilisation in A. nidulans regulated by pH of the medium. Expand

In isolation genetic analysis of a new class of mutants of the mould Aspergillus nidulans, a series of sorbitol mutants is unusual in that they are all non-complementary when combined in heterokaryons, although certain pairs of mutants complement in the corresponding heterozygous diploids. Expand
Regulation of Carbon Metabolism in Filamentous Fungi
Fungi are primarily soil organisms and as agents of decay produce extracellular enzymes degrading many natural polymers, especially polysaccharides (Section 2). The majority of fungi also utilize aExpand
Differential flux through the quinate and shikimate pathways. Implications for the channelling hypothesis.
The qutC gene encoding dehydroshikimate dehydratase has been constitutively overexpressed in Aspergillus nidulans from a range of 1-30-fold over the normal wild-type level. This overexpression leadsExpand
Genetic regulation of the quinic acid utilization (QUT) gene cluster in Aspergillus nidulans.
A large number of quinic acid non-utilizing qut mutants of Aspergillus nidulans deficient in the induction of all three quinic Acid specific enzymes have been analysed and two regulatory genes have been identified. Expand
Beta-galactosidase activity and lactose utilization in Aspergillus nidulans.
Although β-galactosidase activity is not required for mycelial growth on lactose, it is essential for germination of conidia with lactose as the sole carbon source, demonstrating the existence of an alternative (and unknown) mode of lactose utilization. Expand

Isolation and characterization of the positively acting regulatory gene QUTA from Aspergillus nidulans.
The data presented confirm the view deduced by genetical analysis that the QUTA gene of A. nidulans encodes a protein capable of interacting with QUT specific DNA sequences. Expand
