“…Although the palisade parenchyma was reduced by Cd on the adaxial leaf side, the absence of significant changes on the abaxial side may have balanced the photosynthetic capacity. In tolerant species Cd has no effect or may increase the leaf and chlorenchyma thickness (Luković et al, 2012;Jia et al, 2015;Pereira et al, 2016). It is known that T. domingensis photosynthetic activity is related to palisade parenchyma thickness (Santos et al, 2015).…”

“…Plants were transferred to plastic pots containing nutrient solution at 40% of ionic strength (Hoagland and Arnon, 1950) The Cd levels applied were selected as the control (zero Cd), the Cd concentration that caused no toxicity in Schinus molle (10 µM) and the level were Cd was toxic to these plants (50 µM) according to Pereira et al (2016) the levels of Cd were selected to compare with an tolerant species (Schinus molle) as shown by the authors. The experiment was conduced at greenhouse for 60 d; the experimental design was completely randomized with three treatments (Cd concentrations) and ten replicates.…”

Cadmium tolerance of Typha domingensis Pers. (Typhaceae) as related to growth and leaf morphophysiology

Typha domingensis (cattail) is a native macrophyte known by its capacity to tolerate several heavy metals effects and the potential use for phytoremediation. However, in despite that cadmium (Cd) is one of the most toxic pollutants; its effects in T. domingensis biology remain uninvestigated. Thus, the objective of this study was to study the tolerance of T. domingensis to cadmium contamination by evaluating its growth, Cd uptake, leaf anatomy and gas exchange. The experiment was designed using three cadmium concentrations (0, 10 and 50 µM) and ten replicates for 90 days. The cadmium uptake, growth, gas exchange, chlorophyll content and leaf anatomy were evaluated. Data was submitted to ANOVA and Scott-Knott test for P<0.05. Typha domingensis accumulates Cd proportionally to its concentration on the solution and the content of this metal was higher in roots as compared to shoots. Plants showed no significant modifications on growth parameters such as the biomass production, number of leaves, number of clones and the biomass allocation to organs. The photosynthesis, transpiration and chlorophyll content were not modified by Cd. Most anatomical traits evaluated were not modified by the metal but the stomatal density and the proportion of vascular tissues were reduced under 50 µM of Cd. In despite, the leaf anatomy showed no toxicity evidences for any Cd level. The absence of growth reduction and the stability of anatomical and physiological traits give insight about the Cd tolerance of this species. Therefore, T. domingensis is able to overcome Cd toxicity and shows potential for phytoremediation. Keywords

“…Waltheria indica was reported to be a copper (Cu) hyperaccumulator in Sri Lanka (Rajakaruna and Bohm 2002) and a nickel (Ni) hyperaccumulator in Venezuela (Barreto and Casale 2002) whilst in Queensland and Costa Rica it did not show any nickel or copper accumulation (Reeves et al 2007a). Schinus molle L. has been reported as a Cd tolerant species (Paulo-Pereira et al 2015). Buendı´a-Gonzalez et al (2010) demonstrated Pb and Ni accumulation as well as Cr and Cd hyperaccumulation in Prosopis laevigata through in vitro culture.…”

In Mexico, ultramafic complexes are present in different regions from the northwest (Baja California Norte) to the southeast (Chiapas). In this paper, we present the results of the exploration of three ultramafic (serpentine) habitats in central and southern Mexico: Cuicatlán–Concepción Pápalo (Oaxaca), Tehuitzingo–Tecomatlán (Puebla), and San Juan de Otates (Guanajuato). Previous geology studies showed that these complexes are mainly made up of serpentinized peridotites. Soil analyses demonstrated typical ultramafic characteristics such as high content of Mg in relation to Ca, and high concentrations of Fe, Cr, Co, and Ni. Soil samples from Oaxaca and Puebla had similar Ni contents around 2300 mg kg−1, while samples of Guanajuato showed the lowest Ni levels with an average of 200 mg kg−1 as well as for other metals such as Co, Cr, Mn, and Zn. During this study, 83 plant specimens were collected, of which 52 were identified at genus level and 40 at species level. The collected plants belong to 19 different families such as Anacardiaceae, Fabaceae, Acanthaceae, Asteraceae, Sterculiaceae, and Verbenaceae which are also widely present in other ultramafic areas in Iran, Brazil, Sri Lanka, and Costa Rica. Only two Mexican endemic species are included in the collection. Ni hyperaccumulators were not detected at any of the studied sites. Therefore, hyperaccumulation, as a tolerance mechanism of the flora in response to ultramafic geochemical stress, does not seem to be developed in Central Mexico, as observed in the close Costa Rican site of Santa Elena.

“…S. molle plant showed to be resistant to the harsh environmental condition such as high temperature, cold and increasing soil salinity (Lim, 2012). In addition, S. molle plants usually used for the restoration of degraded areas and showed tolerance to heavy metals (Doganlar et al, 2012;Pereira et al, 2016). Toward this approach examine the genetic diversity of S. molle plant is highly needed as no reports available.…”

This study examined the degree of variations in DNA fingerprints associated with slight altitudinal change of Schinus molle grown in Abha region, Saudi Arabia. Seven populations from Schinus molle plants located at 2193.0, 2246.0, 2197.7, 2441.0, 2372.0, 2250.6 and 2175.0 meters had been investigated. The degree of genetic variability was evaluated using random amplified polymorphic DNA (RAPD), mixed RAPD and intersimple sequence repeat markers (ISSR). The genetic similarity coefficients from RAPD analysis revealed the maximum similarity value (89.9%) was between population at 2250.6 m and population at 2175.0 m. The genetic similarity coefficients from mixed RAPD primers displayed the highest similarity value (87.6%) between population at 2246.0 m and population at 2197.7 m. Similarity coefficients from ISSR analysis revealed the highest similarity value (86.2%) among populations at 2193.0 m, 2246.0 m, 2441.0 m and at 2250.6 m. Super tree analysis (RAPD + mixed RAPD + ISSR) showed the highest similarity value (85.5%) between population at 2441.0 m and population at 2250.6 m. In conclusion, marker systems including RAPD, mixed RAPD and ISSR, alone or combined can be effectively used in determining the genetic relationship among Schinus molle plants even at very close populations.
