While biogeographical studies on alien invasive plant species have indicated coevolution with soil biota in their native distribution range, it is unknown whether adaptation to soil biota varies among populations within the native distribution range. The question of local adaptation between plants and their soil biota has important implications for conservation of biodiversity and may justify the use of seed material from local provenances in restoration campaigns. Methodology/Principal Findings: We studied soil biota effects in ten populations of the steppe grass Stipa capillata from two distinct regions, Europe and Asia. We tested for local adaptation at two different scales, both within (ca. 10-80 km) and between (ca. 3300 km) regions, using a reciprocal inoculation experiment in the greenhouse for nine months. Generally, negative soil biota effects were consistent. However, we did not find evidence for local adaptation: both within and between regions, growth of plants in their 'home soil' was not significantly larger relative to that in soil from other, more distant, populations. Conclusions/Significance: Our study suggests that negative soil biota effects can prevail in different parts of a plant species' range. Absence of local adaptation points to the possibility of similar rhizosphere biota composition across populations and regions, sufficient gene flow to prevent coevolution, selection in favor of plasticity, or functional redundancy among different soil biota. From the point of view of plant - soil biota interactions, our findings indicate that the current practice of using seeds exclusively from local provenances in ecosystem restoration campaigns may not be justified.}, language = {en} } @article{VonRaabStraubeRausBazosetal.2019, author = {Von Raab-Straube, Eckhard and Raus, Thomas and Bazos, Ioannis and Cornec, J.

In later years, it was shown that cancer cells exhibit multiple alterations in mitochondrial content, structure, function, and activity. We have stably overexpressed the Friedreich ataxia-associated protein frataxin in several colon cancer cell lines. These cells have increased oxidative metabolism, as shown by concurrent increases in aconitase activity, mitochondrial membrane potential, cellular respiration, and ATP content. Consistent with Warburg's hypothesis, we found that frataxin-overexpressing cells also have decreased growth rates and increased population doubling times, show inhibited colony formation capacity in soft agar assays, and exhibit a reduced capacity for tumor formation when injected into nude mice. Furthermore, overexpression of frataxin leads to an increased phosphorylation of the tumor suppressor p38 mitogen-activated protein kinase, as well as decreased phosphorylation of extracellular signal-regulated kinase. Taken together, these results support the view that an increase in oxidative metabolism induced by mitochondrial frataxin may inhibit cancer growth in mammals}, language = {en} } @article{RohnerRistow2005, author = {Rohner, Ria and Ristow, Michael}, title = {Ein isoliertes Vorkommen kontinentaler Trockenrasen-Pflanzen in den Gorrenbergen bei Medewitz (Hoher Fl{\"a}ming)}, year = {2005}, language = {de} } @article{RistowSeitz2002, author = {Ristow, Michael and Seitz, Birgit}, title = {Zur Kenntnis einiger {\"u}bersehener, wenig beachteter oder verkannter Sippen der Gattungen Vicia und Valerianella in Brandenburg}, year = {2002}, language = {de} } @article{RistowSeitz2004, author = {Ristow, Michael and Seitz, Birgit}, title = {Neue Fundorte - Best{\"a}tigungen - Verluste (299 - 323)}, issn = {1617-5506}, year = {2004}, language = {de} } @article{RistowPanitsaMeyeretal.2022, author = {Ristow, Michael and Panitsa, Maria and Meyer, Stefan and Bergmeier, Erwin}, title = {Factors of detection deficits in vascular plant inventories - an island case study}, series = {Diversity}, volume = {14}, journal = {Diversity}, number = {4}, publisher = {MDPI}, address = {Basel}, issn = {1424-2818}, doi = {10.3390/d14040303}, pages = {12}, year = {2022}, abstract = {The degree of completeness of large-scale floristic inventories is often difficult to judge. We compared prior vascular plant species inventories of the Mediterranean island of Limnos (North Aegean, Greece) with 231 recent records from 2016-2021. Together with the recent records, the known number of vascular plant species on the island is 960 native taxa, 63 established neophytes, and 27 species of as yet casual status for a total of 1050 taxa. We looked at a number of traits (plant family, size, flower color, perceptibility, habitat, reproduction period, rarity, and status) to investigate whether they were overrepresented in the dataset of the newly found taxa. Overrepresentation was found in some plant families (e.g., Poaceae and Chenopodiaceae) and for traits such as hydrophytic life form, unobtrusive flower color, coastal as well as agricultural and ruderal habitats, and late (summer/autumn) reproduction period. Apart from the well-known fact of esthetic bias, we found evidence for ecological and perceptibility biases. Plant species inventories based on prior piecemeal collated data should focus on regionally specific species groups and underrepresented and rare habitats.}, language = {en} } @article{RistowHerrmannIlligetal.2006, author = {Ristow, Michael and Herrmann, Andreas and Illig, Hubert and Klemm, Gunther and Kummer, Volker and Kl{\"a}ge, Hans-Christian and Machatzi, Bernd and Raetzel, Stefan and Schwarz, R. and Zimmermann, Friedrich}, title = {Liste und Rote Liste der etablierten Gef{\"a}ßpflanzen Brandenburgs}, year = {2006}, language = {de} }
