“…Although average Ca concentrations were markedly high in wide gypsophiles, the effect of plant affinity to gypsum on foliar Ca concentrations was not significant, contrasting with the effects on S and Mg. The lack of significant differences in the Ca concentrations of Iberian gypsum plants when phylogeny is accounted for, agrees with the hypothesis that gypsophilic floras may have evolved from calcicole lineages (Heiden et al ., 2022), with a preadaptation to tolerate high Ca concentrations in the soil partly through Ca accumulation. This notion seems highly plausible for the Iberian Peninsula, due to the relatively high Ca concentrations of most taxa (Fig.…”

Summary The analysis of plant elemental composition and the underlying factors affecting its variation are a current hot topic in ecology. Ecological adaptation to atypical soils may shift plant elemental composition. However, no previous studies have evaluated its relevance against other factors such as phylogeny, climate or individual soil conditions. We evaluated the effect of the phylogeny, environment (climate, soil), and affinity to gypsum soils on the elemental composition of 83 taxa typical of Iberian gypsum ecosystems. We used a new statistical procedure (multiple phylogenetic variance decomposition, MPVD) to decompose total explained variance by different factors across all nodes in the phylogenetic tree of target species (covering 120 million years of Angiosperm evolution). Our results highlight the relevance of phylogeny on the elemental composition of plants both at early (with the development of key preadaptive traits) and recent divergence times (diversification of the Iberian gypsum flora concurrent with Iberian gypsum deposit accumulation). Despite the predominant phylogenetic effect, plant adaptation to gypsum soils had a strong impact on the elemental composition of plants, particularly on sulphur concentrations, while climate and soil effects were smaller. Accordingly, we detected a convergent evolution of gypsum specialists from different lineages on increased sulphur and magnesium foliar concentrations.

“…This does not preclude gypsophiles from using other physiological mechanisms to tolerate high Ca in cells. For example, some gypsophiles belonging to Caryophyllaceae display oxalate metabolism ( Palacio et al 2014 ; Muller et al 2017 ), and most of them have likely evolved from calcicolous lineages ( Heiden et al 2022 ; Palacio et al 2022 ).…”

Nutritional strategy underlying plant specialization to gypsum soils

Gypsum soils are amongst the most widespread extreme substrates of the world, occurring in 112 countries. This type of hypercalcic substrate has a suite of extreme physical and chemical properties that make it stressful for plant establishment and growth. Extreme chemical properties include low plant-available (N) and phosphorus (P) and high plant-available sulphur (S) and calcium (Ca), which impose strong nutritional imbalances on plants. In spite of these edaphic barriers, gypsum soils harbour rich endemic floras that have evolved independently on five continents, with highly specialised species. Plants that only grow on gypsum are considered soil specialists, and they have a foliar elemental composition similar to the elemental availability of gypsum soils, with high Ca, S and magnesium (Mg) accumulation. However, the physiological and ecological role of the unique foliar elemental composition of gypsum specialists remains poorly understood, and it is unknown whether it provides an ecological advantage over other generalist species on gypsum soils. This article reviews available literature on the impact of gypsum soil features on plant life and the mechanisms underlying plant adaptation to gypsum environments. We conclude with a hypothesis on the potential role of the nutritional strategy underlying plant specialisation to gypsum soils: Gypsum specialists primarily use SO42- as a counter anion to tolerate high Ca 2+ concentrations in cells and avoid P depletion, which is one of the most limiting nutrients in gypsum soils.
