Asexual development in Aspergillus nidulans begins in superficial hyphae as the programmed
emergence of successive pseudohyphal modules, collectively known as the conidiophore…

The pH regulation of gene expression in Aspergillus nidulans is mediated by pacC, whose
678 residue‐derived protein contains three putative Cys2His2 zinc fingers. Ten pacCc …

Light sensing is very important for organisms in all biological kingdoms to adapt to changing
environmental conditions. It was discovered recently that plant-like phytochrome is involved …

Hyphal tip growth in fungi is important because of the economic and medical importance of
fungi, and because it may be a useful model for polarized growth in other organisms. We …

Gene expression in fungi by ambient pH is regulated via a conserved signalling cascade
whose terminal component is the zinc finger transcription factor PacC/Rim1p. We have …

The veA gene is a light‐dependent regulator governing development and secondary
metabolism in Aspergillus nidulans. We have identified a putative bipartite nuclear localization …

… All of these compounds behave as derepressing Csources with respect to ipnA transcription
(Espeso and Penialva, 1992; this work). In contast, growth in 3% sucrose, 1% D-glucose or 1…

Extremes of pH are an occupational hazard for many microorganisms. In addition to efficient
pH homeostasis, survival effectively requires a regulatory system tailoring the syntheses of …

AbpA, SlaB and AmpA, three demonstrated components of the endocytic internalization
machinery, are strongly polarized in Aspergillus nidulans hyphae, forming a ring that embraces …
