Elemental Defense

The elemental defense hypothesis supports that metal hyperaccumulation in plant tissues serves as a mechanism underpinning plant resistance to herbivores and pathogens. In this study, we investigate the interaction between Odontarrhena lesbiaca and broomrape parasitic species, in the light of the defense hypothesis of metal hyperaccumulation. Plant and soil samples collected from three serpentine sites in Lesbos, Greece were analyzed for Ni concentrations. Phelipanche nowackiana and Phelipanche nana were found to infect O. lesbiaca. In both species, Ni concentration decreased gradually from tubercles to shoots and flowers. Specimens of both species with shoot nickel concentrations above 1000 mg.kg−1 were found, showing that they act as nickel hyperaccumulators. Low values of parasite to O. lesbiaca leaf or soil nickel quotients were observed. Orobanche pubescens growing on a serpentine habitat but not in association with O. lesbiaca had very low Ni concentrations in its tissues analogous to excluder plants growing on serpentine soils. Infected O. lesbiaca individuals showed lower leaf nickel concentrations relative to the non-infected ones. Elevated leaf nickel concentration of O. lesbiaca individuals did not prevent parasitic plants to attack them and to hyperaccumulate metals to their tissues, contrary to predictions of the elemental defense hypothesis.

Ni Accumulation

Serpentinite belongs to the ultramafic group of rocks which contains naturallyoccurring heavy metals such as nickel (Ni). This study is based on the hypothesisthat Ni is present in high amounts in the soil, and it could be taken up by theplants including food crops. The study aims to evaluate the Ni content of the soiland native crops growing in the hill of Adil, Pago, Tanauan, Leyte, Philippineswhere serpentinite rocks are found. Composite soil samples from the surface soil(0-20 cm depth) and plant tissues (roots and leaf samples) were collected anddetermined their pH and Ni content using atomic absorption spectrophotometer.Results revealed that a level of extractable Ni in soils is 27.19 mg/kg-1 on averagebetween food plants and 6.35 mg/kg-1 on soils around bamboo. In terms of root Ni accumulation, pineapple rendered the highest concentration of 84.35 mg/kg-1 and bamboo with 81.15 mg/kg-1. Bamboo and guava leaves accumulated17.45 mg/kg-1 and 15.9 mg/kg-1, respectively. Since Ni is present in thenative plants grown in the area, there is a possible implication that Ni could bebiologically accumulated by people. However, no plants sampled quantified ashyperaccumulator.Keywords - Ecology and conservation, nickel accumulation in serpentinite, experimentalsurvey study, Philippines

Pontechium maculatum, a facultative metallophyte, was collected from four ultramafic localities in Serbia and analysed in terms of micro- and macroelement accumulation. The aim of the study was to reveal trace element profiles and differences in uptake and translocation of heavy metals in populations growing under heavy metal stress. The concentrations of major and trace elements in soil samples (Ca, Mg, Fe, Mn, Ni, Pb, Cr, Zn, Cu, Co, Cd) and in plant tissues (Fe, Mn, Ni, Pb, Cr, Zn, Cu, Co, Cd) are presented. The results of our analysis indicate that P. maculatum efficiently absorbs Zn and Cr, while for most of the other elements accumulation levels fit in the range of values obtained for several other species from ultramafic localities on the Balkan Peninsula.

The objective of this study was to evaluate the biomass production and to characterize a 7-year-old Eucalyptus benthamii stands in the Pampa-RS Biome. Initially, a sample inventory was performed for the dendrometric characterization of the stand. For the determination of biomass, nine trees were felled and fractionated in wood, bark, branch and leaves. Soil samples and plant tissues were collected and analyzed for nutritional characterization and determination of biological utilization coefficient (BUC). The average annual increment (AAI) with bark was 49.87 m3 ha-1. The biomass production was 192 Mg ha-1, distributed in wood (81.2%)> branches (11%)> bark (6,5%)> leaves (1,3%). The leaves component presented the highest nutrient concentration and the wood the highest amounts of nutrients allocated in the biomass, except for Ca and Mg, observed in the bark. The highest BUC was observed in the wood. Mg was the nutrient that provided the best efficiency with a yield of 6,014 kg of wood per kg of Mg used, followed by S, P, Ca, K and N.

AbstractLittle empirical evidence is available whether allopolyploid species combine or merge adaptations of parental species. The allopolyploid species Arabidopsis kamchatica is a natural hybrid of the diploid parents A. halleri, a heavy metal hyperaccumulator, and A. lyrata, a non-hyperaccumulating species. Zinc and cadmium were measured in native soils and leaf tissues in natural populations, and in hydroponic cultures of A. kamchatica and A. halleri. Pyrosequencing was used to estimate homeolog expression ratios. Soils from human modified sites showed significantly higher Zn concentrations than non-modified sites. Leaf samples of A. kamchatica collected from 40 field localities had > 1,000 µg g-1 Zn in over half of the populations, with significantly higher amounts of Zn concentrations in plants from human modified sites. In addition, serpentine soils were found in two populations. Most genotypes accumulated >3000 µg g-1 of Zn in hydroponic culture with high variability among them. Genes involved in hyperaccumulation showed a bias in the halleri-derived homeolog. A. kamchatica has retained constitutive hyperaccumulation ability inherited from A. halleri. Our field and experimental data provides a compelling example in which the inheritance of genetic toolkits for soil adaptations likely contributed to the habitat expansion of an allopolyploid species.

The aim of the present study was to compare trace element profiles and the differences in uptake and translocation of trace elements in plants from five populations (three from Greece and two from Serbia) belonging to three subspecies of Silene parnassica Boiss. & Sprun. growing on ophiolitic substrates. For comparison of the subspecies, bioconcentration and translocation factors were used, as well as Spearman’s rank correlation coefficients for concentrations of elements in root and shoot samples. Chemical characteristics of the soil samples (pH, organic C, P2O5, K2O, Ca, Fe, Mg, Mn, Ni, Zn, Cu, Cr, Co, Cd and Pb) and plant samples (P2O5, K2O, Ca, Fe, Mg, Mn, Ni, Zn, Cu, Cr, Co, Cd and Pb) were determined, as well as bioconcentration and translocation factors and correlation matrices. All the three subspecies acted as strong Ni accumulators, with equal concentrations of Ni in roots and shoots, the values being several times higher than 100 mg kg–1, exceeding concentrations of available Ni in the soil. Concentrations of Cu and Cr in the aboveground plant tissues in samples from three localities were several times higher than expected, even for plants growing on metalliferous soils, exceeding, by multiple times, the available concentrations in the soil samples.

Fertility Analysis

The eucalypt forests of the central Queensland serpentine landscape on the eastern coast of Australia are dominated by two overstorey species. These are Eucalyptus fibrosa F.Muell. subsp. fibrosa, the most dominant tree occurring throughout the landscape, and Corymbia xanthope A.R.Bean & Brooker, a serpentine endemic species which has a more restricted distribution. We hypothesised that the structure and foliage elements of the eucalypt forests could be used as biological indicators of the severity of the serpentine soils. This was tested by surveying 30 plots (50 × 20 m) within the upland landform patterns of the central Queensland serpentine landscape. The structure of the forests and abundance of the species were recorded and foliage samples from the dominant tree E. fibrosa subp. fibrosa were collected and analysed for metal and nutrient content. Soil samples from each site were collected and analysed for major cations, bio-available metals and fertility. Analysis of the data showed that there are significant correlations between the structure of the eucalypt forests and the landform patterns and soil chemistry. The relative basal area of C. xanthope is a useful measure of the severity of the serpentine soils and correlates to the soil Mg : Ca quotients. The tree E. fibrosa subsp. fibrosa was found to regulate its uptake of soil elements and cannot be used as an indicator of soil elements.

A study was conducted over 15 years in apple, peach, pear, citrus, grapevine and olive orchards in different locations in Syria. The study aimed at monitoring and evaluating the long-term nutrient behaviour in plants and soil in order to suggest measures for nutrient management improvement. Leaf and soil samples were collected in the years 1982, 1987, 1990 and 1997. The soils were characterized by high pH values, high CaCO 3 and low to medium organic matter contents. Due to the unfavourable soil conditions and ill-chosen fertilizer use, the nutrient balance in the plant tissues was disturbed. To correct the situation, the application of improved nutrient management practices was suggested.

Toxic Heavy Metals

Serpentine soils are a stressful growing environment for plants, largely due to nutrient deficiencies and high concentrations of toxic heavy metals (e.g., Ni). Plants have evolved various adaptations for tolerating these extreme environments, including metal hyperaccumulation into above-ground tissues. However, the adaptive significance of metal hyperaccumulation is a topic of debate, with several non-mutually-exclusive hypotheses under study. For example, the inadvertent uptake hypothesis (IUH) states that heavy metal accumulation is a consequence of an efficient nutrient-scavenging mechanism for plants growing in nutrient-deficient soils. Thus, it is possible that metal hyperaccumulation is simply a byproduct of non-specific ion transport mechanisms allowing plants to grow in nutrient-deficient soils, such as serpentine soils, while simultaneously tolerating other potentially toxic heavy metals. Furthermore, some nutrient needs are tissue-specific, and heavy metal toxicity can be more pronounced in reproductive tissues; thus, studies are needed that document nutrient and metal uptake into vegetative and reproductive plant tissues across species of plants that vary in the degree to which they accumulate soil metals. To test these ideas, we grew nine plant species that are variously adapted to serpentine soils (i.e., Ni-hyperaccumulating endemic, non-hyperaccumulating endemic, indicator, or indifferent) in a common garden greenhouse experiment. All species were grown in control soils, as well as those that were amended with the heavy metal Ni, and then analyzed for macronutrient (Ca, Mg, K, and P), micronutrient (Cu, Fe, Zn, Mn, and Mo), and heavy metal (Cr and Co) concentrations in their vegetative and reproductive organs (leaves, anthers, and pistils). In accordance with the IUH, we found that hyperaccumulators often accumulated higher concentrations of nutrients and metals compared to non-hyperaccumulating species, although these differences were often organ-specific. Specifically, while hyperaccumulators accumulated significantly more K and Co across all organs, Cu was higher in leaves only, while Mn and Zn were higher in anthers only. Furthermore, hyperaccumulators accumulated significantly more Co and Mo across all organs when Ni was added to the soil environment. Our work provides additional evidence in support of the IUH, and contributes to our understanding of serpentine adaptation in plants.

Phytoremediation is an alternative to traditional chemical and ways of treating polluted soils. The current study was carried out to investigate the phytoremediation of soil contaminated with nickel (Ni) by Lepidium sativum. Soil samples from 0 to 10 cm depth were collected. Lepidium sativum was transplanted in pots containing 5 kg of the collected soils. Central composite design and response surface methodology were employed in order to illustrate the nature of the response surface in the experimental design and explain the optimal conditions of the independent variables. Different concentrations for Ni (1 to 20 mg kg-1) and times for collecting samples (10 to 40 days) were used. The results showed the amount of Ni removed was ranged from 8.62 mg kg-1 (Ni concentration of 20 mg kg-1 and time for taking samples of 10 days) to 7.066 mg kg-1 (Ni concentration of 10.50 mg kg-1 and time for taking samples of 40days). Additionally, the findings explained that the Lepidium sativum is an effective accumulator plant for phytoremediation of Ni polluted soils. Optimum conditions for nickel concentration and time for taking samples were 19.66 mg kg-1 and 39.28 days, respectively. For the optimum condition, the amount of Ni removed was 10.8095 mg kg-1.
