|Title:||The Aspergillus nidulans xprG (phoG) gene encodes a putative transcriptional activator involved in the response to nutrient limitation||Contributor(s):||Katz, ME (author); Gray, K (author); Cheetham, BF (author)||Publication Date:||2006||DOI:||10.1016/j.fgb.2005.12.001||Handle Link:||https://hdl.handle.net/1959.11/140||Abstract:||The Aspergillus nidulans xprG gene is involved in the regulation of extracellular proteases. A plasmid which complemented the xprG2 mutation was shown to carry the phoG gene, reported to encode an acid phosphatase. Two phoGDelta mutants were constructed and were identical in phenotype to an xprG2 mutant. Null mutants were unable to use protein as a carbon or nitrogen source, have lost a repressible acid phosphatase and have pale conidial color. XprG shows similarity to the Ndt80 transcriptional activator, which regulates the expression of genes during meiosis in Saccharomyces cerevisiae. The xprG1 gain-of-function mutant contains a missense mutation in the region encoding the putative DNA-binding domain. The response to carbon, nitrogen, sulfur, and phosphate limitation is altered in xprG(-) mutants suggesting that XprG is involved in a general response to starvation. Ndt80 may also be involved in sensing nutritional status and control of commitment to meiosis in S. cerevisiae.||Publication Type:||Journal Article||Source of Publication:||Fungal Genetics and Biology, 43(3), p. 190-199||Publisher:||Elsevier Science B.V.||Place of Publication:||San Diego||ISSN:||1087-1845||Field of Research (FOR):||060503 Microbial Genetics||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Statistics to Oct 2018:||Visitors: 121
