Background and aims Pseudometallophytes are model organisms for adaptation and population differentiation because they persist in contrasting edaphic conditions of metalliferous and non-metalliferous habitats. We examine patterns of genetic divergence and local adaptation of Biscutella laevigata to assess historical and evolutionary processes shaping its genetic structure. Methods We sampled all known populations of B. laevigata in Poland and analyzed respective soil metal concentrations. For genotyping we used nine nuclear microsatellite loci. Population genetic pools were identified (Bayesian clustering) and we estimated genetic parameters and demographic divergence between metallicolous and non-metallicolous populations (ABCapproach). Results Populations clustered into two groups which corresponded to their edaphic origin and diverged 1,200 generations ago. We detected a significant decrease in genetic diversity and evidence for a recent bottleneck in metallicolous populations. Genetic structure was unrelated to site distribution but is rather influenced by environmental conditions (i.e. soil metal concentration). Conclusions The intriguing disjunctive distribution of B. laevigata in Poland results from a fragmentation of the species range during the Holocene, rather than recent long-distance-dispersal events. The genetic structure of populations, however, continues to be modified by microevolutionary processes at anthropogenic sites. These clear divergence patterns promote B. laevigata as a model species for plant adaptation to polluted environments.

“…Voucher specimens (CS: WH06051793, YP: WH06051794) were deposited at the Wuhan University Herbarium (WH). Soil Cu concentrations at these sampling sites were measured following the method described by Ye et al (2012) (Appendix 1). Total genomic DNA was extracted from silica gel-dried leaves of one individual of C. communis sampled from the CS population using the QIAGEN DNA Extraction Kit (QIAGEN, Hilden, Germany).…”

“…Commelina communis L. (Commelinaceae), commonly known as dayfl ower, is a pseudometallophyte (facultative metallophyte) that is distributed extensively on both cupriferous habitats and surrounding nonmetalliferous sites ( Tang et al, 1999( Tang et al, , 2001Ye et al, 2012 ). It is an annual multibranched herb that exhibits sexual reproduction and clonal propagation ( Tang et al, 1999 ;Ushimaru et al, 2007 ;Ye et al, 2012 ). This species can also accumulate extraordinarily high concentrations of copper, with foliar Cu concentration reaching as much as 1000 mg/kg ( Tang et al, 1997 ;Shu et al, 2001 ).…”

• Premise of the study: Microsatellite primers were developed for the pseudometallophyte Commelina communis (Commelinaceae), an important pioneer plant for phytoremediation of copper-contaminated soil. Two wild populations collected from metalliferous and nonmetalliferous sites were used to assess the polymorphism at each locus.• Methods and Results: Based on the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) method, a total of 34 pairs of simple sequence repeat (SSR) markers were designed. When 40 specimens from two populations were screened, 12 microsatellite loci were found to be highly polymorphic. The number of alleles per locus ranged from one to 11 and the observed and expected heterozygosity per locus ranged from 0.000 to 1.000 and from 0.195 to 0.941, respectively.• Conclusions: These markers will be useful for examining genetic diversity, population structure, and gene flow in populations of C. communis under different edaphic conditions and guiding sustainable management plans for phytoremediation.

Communicated by Mâris KïaviòðThe aim of the present study was to determine if individuals of Rumex hydrolapathum Huds native to saline wetlands are able to tolerate high concentration of biogenous heavy metals Zn and Mn in substrate and to accumulate high concentration of these metals in aboveground parts. Plant physiological status was monitored by using non-destructive analysis of chlorophyll and chlorophyll a fluorescence. R. hydrolapathum plants accumulated up to 1840 mg·kg -1 Zn and 6400 mg·kg -1 Mn in older leaves. The usefulness of monitoring changes in chlorophyll concentration and chlorophyll a fluorescence parameters to predict physiological response of R. hydrolapathum plants to excess Zn and Mn was not supported, as the lack of significant changes indicated that the model species showed adaptation to increased amount of metals in actively photosynthesizing tissues. It appears that Zn and Mn tolerance of R. hydrolapathum is based primarily at the physiological level where metal accumulation in younger leaves and roots is restricted, and development of new leaves is promoted together with induction of senescence in older leaves that have accumulated the majority of Zn and Mn. R. hydrolapathum can be characterised as a very promising model species for further studies for practical phytoremediation needs.
