The nsdC gene encoding a putative C2H2-type transcription factor is a key activator of sexual development in Aspergillus nidulans.
The formation of the Aspergillus nidulans fruiting body is affected by a number of genetic and environmental factors. Here, the nsdC (never in sexual development) gene-encoding a putative transcription factor carrying a novel type of zinc-finger DNA-binding domain consisting of two C(2)H(2)'s and a C(2)HC motif that are highly conserved in most fungi but not in plants or animals-was investigate...
متن کاملThe Drosophila stonewall gene encodes a putative transcription factor essential for germ cell development.
The differentiation of Drosophila germ cells is a useful model for studying mechanisms of cell specification. We report the identification of a gene, stonewall, that is required for germ cell development. Mutations in stonewall block proper oocyte differentiation and frequently cause the presumptive oocyte to develop as a nurse cell. Eventually, germ cells degenerate apoptotically. Stonewall is...
متن کاملThe Zn(II)2Cys6 putative Aspergillus nidulans transcription factor repressor of sexual development inhibits sexual development under low-carbon conditions and in submersed culture.
Here we have characterized the putative Zn(II)2Cys6 transcription factor RosA from the filamentous fungus Aspergillus nidulans. The rosA gene encodes a protein of 713 aa, which shares 38% sequence similarity to Pro1 from Sordaria macrospora. In contrast to Pro1, which promotes the transition from protoperithecia to perithecia, RosA is a negative regulator of sexual development in A. nidulans. T...
متن کاملAspergillus nidulans catalase-peroxidase gene (cpeA) is transcriptionally induced during sexual development through the transcription factor StuA.
Catalases, peroxidases, and catalase-peroxidases are important enzymes to cope with reactive oxygen species in pro- and eukaryotic cells. In the filamentous fungus Aspergillus nidulans three monofunctional catalases have been described, and a fourth catalase activity was observed in native polyacrylamide gels. The latter activity is probably due to the bifunctional enzyme catalase-peroxidase, w...
متن کاملNsdD is a key repressor of asexual development in Aspergillus nidulans.
Asexual development (conidiation) of the filamentous fungus Aspergillus nidulans occurs via balanced activities of multiple positive and negative regulators. For instance, FluG (+) and SfgA (-) govern upstream regulation of the developmental switch, and BrlA (+) and VosA (-) control the progression and completion of conidiation. To identify negative regulators of conidiation downstream of FluG-...
