“…We found the highest private allelic richness in the Mediterranean region and a decreasing east‐to‐west gradient in private allelic richness in temperate Europe, from the Pannonian to the Continental to the Atlantic region (Figures3, 7; Appendix ). European southern glacial refugia have been postulated in the Iberian Peninsula, Italy, the Balkans, Anatolia, and the region around the Black Sea for a range of plant and animal species (Ali et al, 2017; Bartish, Kadereit, & Comes, 2006; Comes & Kadereit, 1998; Hewitt, 1996). The occurrence of private alleles suggests a long‐lasting in situ history (Médail & Diadema, 2009).…”

Many ephemeral mudflat species, which rely on a soil seed bank to build up the next generation, are endangered in their natural habitat due to the widespread regulation of rivers. The aim of the present study was to elucidate the role of the soil seed bank and dispersal for the maintenance of genetic diversity in populations of nearnatural river habitats and anthropogenic habitats created by traditional fish farming practices using Cyperus fuscus as a model. Using microsatellite markers, we found no difference in genetic diversity levels between soil seed bank and above-ground population and only moderate differentiation between the two fractions. One possible interpretation is the difference in short-term selection during germination under specific conditions (glasshouse versus field) resulting in an ecological filtering of genotypes out of the reservoir in the soil. River populations harbored significantly more genetic diversity than populations from the anthropogenic pond types. We suggest that altered levels and patterns of dispersal together with stronger selection pressures and historical bottlenecks in anthropogenic habitats are responsible for the observed reduction in genetic diversity. Dispersal is also supposed to largely prohibit genetic structure across Europe, although there is a gradient in private allelic richness from southern Europe (high values) to northern, especially north-western, Europe (low values), which probably relates to postglacial expansion out of southern and/or eastern refugia.

“…As Microthlaspi erraticum is found almost exclusively in soil derived from Ca 2+ -rich but Mg 2+ -poor bedrock (Kimmig et al, 2001;Ali et al, 2017), we speculated that an adaptation regarding the targeted uptake of Mg 2+ might have evolved that gives the species an evolutionary advantage over other Brassicaceae species. Mg 2+ is an essential bivalent ion with vital functions as a co-factor with ATP in various enzymatic reactions and as central ion in the porphyrine ring of chlorophyll molecules.…”

“…Here, the genome assembly of M. erraticum is reported. M. erraticum is an interesting plant on which to study environmental adaptation, as it has a wide distribution range throughout warm temperate Europe and Central Asia ( Ali et al., 2016a ; Ali et al., 2016b ; Ali et al., 2017 ). The species occurs almost exclusively in soil derived from calcium carbonate-rich bedrock und usually grows on well-drained loamy, somewhat open areas ( Ali et al., 2017 ).…”

Similar to A. thaliana , M. erraticum usually is a winter annual, but has longer seed dormancy, requires vernalisation, and so does not produce a second flowering generation in autumn ( Baskin and Baskin, 1979 ).…”

The Genome of Microthlaspi erraticum (Brassicaceae) Provides Insights Into the Adaptation to Highly Calcareous Soils

Microthlaspi erraticum is widely distributed in temperate Eurasia, but restricted to Ca 2+-rich habitats, predominantly on white Jurassic limestone, which is made up by calcium carbonate, with little other minerals. Thus, naturally occurring Microthlaspi erraticum individuals are confronted with a high concentration of Ca 2+ ions while Mg 2+ ion concentration is relatively low. As there is a competitive uptake between these two ions, adaptation to the soil condition can be expected. In this study, it was the aim to explore the genomic consequences of this adaptation by sequencing and analysing the genome of Microthlaspi erraticum. Its genome size is comparable with other diploid Brassicaceae, while more genes were predicted. Two Mg 2+ transporters known to be expressed in roots were duplicated and one showed a significant degree of positive selection. It is speculated that this evolved due to the pressure to take up Mg 2+ ions efficiently in the presence of an overwhelming amount of Ca 2+ ions. Future studies on plants specialized on similar soils and affinity tests of the transporters are needed to provide unequivocal evidence for this hypothesis. If verified, the transporters found in this study might be useful for breeding Brassicaceae crops for higher yield on Ca 2+-rich and Mg 2+-poor soils.
