The Aspergillus nidulans bimA gene is required for mitosis. Loss of function mutations in bimA cause cells to arrest growth with condensed chromatin and a short, metaphaselike mitotic spindle. bimA is a member of a gene family defined by a repeated motif called the Tetratrico Peptide Repeat (TPR), which is found in genes from bacteria, yeast and insects.(More)
Aspergillus nidulans brlA, abaA, and wetA form a dependent pathway that regulates asexual reproductive development. The order in which these genes are expressed determines the outcome of development. Expression of brlA in vegetative cells leads to activation of abaA and wetA, cessation of vegetative growth, cellular vacuolization, and spore formation. By(More)
Gene-silencing mechanisms are being shown to be associated with an increasing number of fungal developmental processes. Telomere position effect (TPE) is a eukaryotic phenomenon resulting in gene repression in areas immediately adjacent to telomere caps. Here, TPE is shown to regulate expression of transgenes on the left arm of chromosome III and the right(More)
Telomere length varies between germline and somatic cells of the same organism, leading to the hypothesis that telomeres are lengthened during meiosis. However, little is known about the meiotic telomere length in many organisms. In the filamentous fungus Aspergillus nidulans, the telomere lengths in hyphae and asexual spores are invariant.
