“…However, no differences in genetic diversity between metallicolous and nonmetallicolous populations have been consistently found in the species investigated to date (Vekemans and Lefèbvre, 1997;Quintela-Sabarís et al, 2010), such as A. halleri (Pauwels et al, 2005), A. bertolonii (Mengoni et al, 2003) and M. laricifolia ssp. ophiolitica (Moore et al, 2013), and neither have they been found here (Table 2).…”

Evolution of nickel hyperaccumulation and serpentine adaptation in the Alyssum serpyllifolium species complex

Metal hyperaccumulation is an uncommon but highly distinctive adaptation found in certain plants that can grow on metalliferous soils. Here we review what is known about evolution of metal hyperaccumulation in plants and describe a population-genetic analysis of the Alyssum serpyllifolium (Brassicaceae) species complex that includes populations of nickelhyperaccumulating as well as non-accumulating plants growing on serpentine (S) and non-serpentine (NS) soils, respectively. To test whether the S and NS populations belong to the same or separate closely related species, we analysed genetic variation within and between four S and four NS populations from across the Iberian peninsula. Based on microsatellites, genetic variation was similar in S and NS populations (average H o = 0.48). The populations were significantly differentiated from each other (overall F ST = 0.23), and the degree of differentiation between S and NS populations was similar to that within these two groups. However, high S versus NS differentiation was observed in DNA polymorphism of two genes putatively involved in adaptation to serpentine environments, IREG1 and NRAMP4, whereas no such differentiation was found in a gene (ASIL1) not expected to play a specific role in ecological adaptation in A. serpyllifolium. These results indicate that S and NS populations belong to the same species and that nickel hyperaccumulation in A. serpyllifolium appears to represent a case of adaptation to growth on serpentine soils. Further functional and evolutionary genetic work in this system has the potential to significantly advance our understanding of the evolution of metal hyperaccumulation in plants.

“…The observation of multiple origins of tolerant populations has raised the question of whether or not all individuals of a given species are equally capable of growing on these soils (Westerbergh ; Quintela‐Sabarís et al . ). However, physiological or morphological differentiation leading to greater tolerance of serpentine or heavy metals in the populations growing on these soils has been demonstrated in several studies (Yokoo et al .…”

“…Serpentine specialists are often smaller, flower earlier and have smaller or otherwise less conspicuous flowers than their relatives on normal soils (Macnair & Gardner ; Baldwin ; O'Dell & Rajakaruna ). With the exception of the high magnesium concentration, other metalliferous soils, such as those derived from mine tailings, present many of the same challenges as do serpentine soils (Macnair & Gardner ), and many serpentine‐tolerant species have been able to expand onto mine tailings when this habitat became available (e.g., Cistus ladanifer , Quintela‐Sabarís ; Silene paradoxa , Mengoni et al . ).…”

The origin of the serpentine endemic Minuartia laricifolia subsp. ophiolitica by vicariance and competitive exclusion

2013

Serpentine soils harbour a unique flora that is rich in endemics. We examined the evolution of serpentine endemism in Minuartia laricifolia, which has two ecologically distinct subspecies with disjunct distributions: subsp. laricifolia on siliceous rocks in the western Alps and eastern Pyrenees and subsp. ophiolitica on serpentine in the northern Apennines. We analysed AFLPs and chloroplast sequences from 30 populations to examine their relationships and how their current distributions and ecologies were influenced by Quaternary climatic changes. Minuartia laricifolia was divided into four groups with a BAPS cluster analysis of the AFLP data, one group consisted only of subsp. ophiolitica, while three groups were found within subsp. laricifolia: Maritime Alps, north-western Alps and central Alps. The same groups were recovered in a neighbour-joining tree, although subsp. ophiolitica was nested within the Maritime Alps group of subsp. laricifolia. Subspecies ophiolitica contained three different chloroplast haplotypes, which were also found in the Maritime Alps group of subsp. laricifolia. Given its high genetic diversity, subsp. ophiolitica appears to have arisen from subsp. laricifolia by vicariance instead of by long-distance dispersal. Genetic and geographic evidence point to the Maritime Alps populations of subsp. laricifolia as the closest relatives of subsp. ophiolitica. We hypothesize that M. laricifolia was also able to grow on nonserpentine rocks in the northern Apennines during glacial periods when the vegetation was more open, but that only the serpentine-adapted populations were able to persist until the present due to their competitive exclusion from more favourable habitats.

“…Also results for vascular plants are not always supportive. Quintela-Sabarís et al (2010) and Kolář et al (2014b) report no evidence of genetic differentiation between serpentinite and non-serpentinite populations of target vascular plants. Kolář et al (2014a), by contrast, report Mg stress as an adaptive character of Knautia arvensis.…”

Peat mosses are a key functional group in peatlands, driving biogeochemical cycles, habitat development and changes in species composition. They are generally intolerant of calcium and magnesium bicarbonate, but some species are adapted to mineral-rich fens. A previous study found a coincidence between genetic variation and the ability to tolerate high pH/calcium levels in Sphagnum warnstorfii. Here we compare its microsatellite variation with that of two rarer calcium-tolerant species (Sphagnum subnitens, S. contortum), using a novel data set from Eurasia. Because physiological experiments indicate that S. warnstorfii can tolerate high magnesium levels, we included also samples from dolomite and serpentinite. Genetic diversity of S. warnstorfii was higher than that of other species. The Bayesian analysis in program Structure resulted in two population groups of S. warnstorfii. One group coincided with dolomite (Italy, Austria, Estonia) and moderately magnesium-rich (but calcium-poor) rocks (serpentinite, metadolerite, cordieritebearing migmatite on the Bohemian Massif), while the second one coincided with magnesiumpoor bedrock across Eurasia. The principal coordinate analysis revealed a cline between populations from magnesium-rich and magnesium-poor bedrocks, with populations from dolomite and serpentinite forming one extreme. Populations from magnesium-poor bedrock located far from any dolomite or serpentinite formed the opposite extreme of the cline. We demonstrate for the first time that magnesium toxicity may drive bryophyte microevolution, as has repeatedly been shown for vascular plants, including ferns. K e y w o r d s: Bryophyta,
