Timing and deciphering mitochondrial DNA macro-haplogroup R0 variability in Central Europe and Middle East (2008)

Brandstätter, Anita, Zimmermann, Bettina, Wagner, Janine, Göbel, Tanja, Röck, Alexander W, Salas, Antonio, ...

Abstract Background Nearly half of the West Eurasian assemblage of human mitochondrial DNA (mtDNA) is fractioned into numerous sub-lineages of the predominant haplogroup (hg) R0. Several hypotheses...

xylP Promoter-Based Expression System and Its Use for Antisense Downregulation of the Penicillium chrysogenum Nitrogen Regulator NRE

Zadra, Ivo, Abt, Beate, Parson, Walther, Haas, Hubertus

A highly inducible fungal promoter derived from the Penicillium chrysogenum endoxylanase (xylP) gene is described. Northern analysis and the use of a β-glucuronidase (uidA) reporter gene strategy...

Regulation of freA, acoA, lysF, and cycA Expression by Iron Availability in Aspergillus nidulans

Oberegger, Harald, Schoeser, Michelle, Zadra, Ivo, Schrettl, Markus, Parson, Walther, Haas, Hubertus

In the filamentous fungus Aspergillus nidulans, iron homeostasis is regulated at the transcriptional level by the negative-acting GATA factor SREA. In this study the expression of a putative...

Characterization of the Aspergillus nidulans transporters for the siderophores enterobactin and triacetylfusarinine C.

Haas, Hubertus, Schoeser, Michelle, Lesuisse, Emmanuel, Ernst, Joachim F, Parson, Walther, Abt, Beate, ...

The filamentous ascomycete Aspergillus nidulans produces three major siderophores: fusigen, triacetylfusarinine C, and ferricrocin. Biosynthesis and uptake of iron from these siderophores, as well as...

Colour-assortative mating among populations of Tropheus moorii, a cichlid fish from Lake Tanganyika, East Africa

Salzburger, Walter, Niederstätter, Harald, Brandstätter, Anita, Berger, Burkhard, Parson, Walther, Snoeks, Jos, ...

The species flocks of cichlid fishes in the East African Lakes Tanganyika, Malawi and Victoria are prime examples of adaptive radiation and explosive speciation. Several hundreds of endemic species...
