Abstract
The filamentous fungus Aspergillus nidulans reproduces asexually through conidiospores, which are continuously generated at morphologically differentiated structures, the conidiophores. In contrast to vegetative, multinucleate cells, spore formation requires a strict coordination of mitosis and cytokinesis. It was shown recently that the key regulator of the cell cycle in A. nidulans NimXCdc2 and a G1/S cyclin, PclA, are transcriptionally upregulated during development. Here we show that PclA accumulates in the nucleus and interacts with NimXCdc2. We propose that PclA modulates the kinase activity of NimXCdc2 during spore formation.Keywords
