Enhancers of conidiation mutants in Aspergillus nidulans.
Mutants at a number of loci, designated sthenyo, have been isolated as enhancers of the oligoconidial mutations at the medA locus. Two loci have been mapped: sthA on linkage group I, and sthB on linkage group V. Two probable alleles have been identified at each locus but two further mutants were unlinked to either sthA or sthB. Neither sthA nor sthB mutants have conspicuous effects on morpholog...
متن کاملA quantitative survey of conidiation mutants in Aspergillus nidulans.
A quantitative survey has been made of conidiation mutants in Aspergillus nidulans. Conidiation mutants were 6 to I 3 times more numerous than auxotrophic mutants, but growth tests showed that the mutant defect in 85 % of the conidiation mutants was not confined to conidiation. The number of loci specifically involved in conidiation was estimated to be 45 to 150. Mutants were classified accordi...

15 صفحه اولFunctional Analysis of the α-1,3-Glucan Synthase Genes agsA and agsB in Aspergillus nidulans: AgsB Is the Major α-1,3-Glucan Synthase in This Fungus
Although α-1,3-glucan is one of the major cell wall polysaccharides in filamentous fungi, the physiological roles of α-1,3-glucan remain unclear. The model fungus Aspergillus nidulans possesses two α-1,3-glucan synthase (AGS) genes, agsA and agsB. For functional analysis of these genes, we constructed several mutant strains in A. nidulans: agsA disruption, agsB disruption, and double-disruption...
متن کاملSynthesis and Characterisation of the Europium (III) Dimolybdo-Enneatungsto-Silicate Dimer, [Eu(α-SiW9Mo2O39)2]13−
The chemistry of polyoxometalates (POMs) keeps drawing the attention of researchers, since they constitute a family of discrete molecular entities whose features may be easily modulated. Often considered soluble molecular oxide analogues, POMs possess enormous potential due to a myriad of choices concerning size, shape and chemical composition that may be tailored in order to fine-tune their ph...
