Idioblasts with calcium oxalate crystals (druses) were observed in cells of spongy parenchyma and were found to be visually more abundant in PG leaves. (C,D) Pedra de Guaratiba (PG) mangrove: epicuticular wax in plates (pl) in all surfaces, including next to stomata. In all samples evaluated, the cell wall of water storage parenchyma presented an intense reaction, indicating the presence of pectic mucilage. Vascular bundles were observed to be the collateral type with fibers in the most developed units forming a cap protecting the phloem (Fig. The bark is light brown with vertical ridges and can grow a single- or multi-stemmed trunk. The length of abaxial epidermal cells from plants of the three mangroves were, however, found to be statistically similar (Pad>0.05), even though longer abaxial epidermal cells were found in M (14.202.09m) compared to abaxial epidermal cells from CG (12.21.46m) (Padj=0.007; Fig. https://doi.org/10.1007/s11356-020-08606-6 (2020).

Here, we investigated, comparatively, morphoanatomical attributes/traits and the presence of PTEs in L. racemosa leaves in different mangrove areas. The amount (mg/kg) of main elements responsible for variance in component 1, consisting of Ba, Na, Ca, Mn, Ni, Pb, Cd, as well as component 2, consisting of B, Cd, Ni, Pb, Ca, Zn and Cu, did not differ significantly among leaf samples collected in CG, M and PG (Padj>0.05; see Supplementary Fig. Different studies of mangroves have shown the presence of metals, metalloids and plasticizers in leaves1,3,7,8. Laguncularia - Wikipedia J. Environ. The absence of toxin diffusion through L. racemosa leaf tissue along Sepetiba Bay suggests, as noted above, that this species is resilient to the levels of pollution in that area. https://doi.org/10.1590/S0100-204X2006000600004 (2006). (B) Mangroves around Sepetiba Bay where Laguncularia racemosa leaves were collected (*). ADS Native to the coasts of western Africa from Senegal to Cameroon, the Atlantic Coast of the Americas from Bermuda and Florida to the Bahamas, Mexico, the Caribbean, and south to Brazil; and on the Pacific Coast of the Americas from Mexico to northwestern Peru, including the Galpagos Islands. Working with others to conserve, protect and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people. We also used one-way ANOVA with Tukey's post hoc test to compare difference in measurements between the intercostal region (epidermis and mesophyll traits) and main rib (epidermis and vascular system traits) of L. racemosa leaves among the three sampled mangroves. The salts, mucilage and other substances excreted by this secretory structure first accumulate in the cavity and thereafter are most likely released to the external environment through the epidermal pore (Figs. These triterpenes also increase the permeability that helps plants eliminate salts36. Laguncularia racemosa (L.)

Laguncularia racemosa grows as medium to large trees producing trunks to 50 cm wide. PTEs like Cd, Cr, Pb and Zn present high toxicity to the environment when in high quantity, and their significant bioaccumulation causes many problems in ecosystems because they are not biologically degraded, but rather accumulate in biota and in abiotic environments as trapped particulates in mangrove sediments31. The detection of PTEs in L. racemosa leaves shows that the species has a relevant role as an ecological indicator in mangroves and that it may serve as a test organism for future studies.

The bark is light brown with vertical ridges. Establishing of reference plant` for inorganic characterization of different plant species by chemical fingerprinting. Thus, given the increasing conversion of land use and vegetative degradation on the Brazilian Atlantic coast, the suppression of L. racemosa would only further the loss of important ecosystem functions. Light microscopy anatomical analysis of Laguncularia racemosa leaves collected in different mangroves in Rio de Janeiro (Brazil). 107(1), 99107. The adaxial epidermal cells in plants from M were longer (19.303.07m) than those from PG (17.002.03m) and CG (15.102.00m) (Padj<0.05; Fig. Bull. Michael G.

Principal Component Analysis (PCA) was performed in a bidimensional plane (component/dimension 1 and 2) in order to identify the main chemical elements responsible for data variance in leaves collected throughout the study site. Sample plasticity was observed in the biometric leaf traits of L. racemosa among Marambaia (M), Coroa Grande (CG), and Pedra de Guaratiba (PG) (Fig. Adv. Biotemas 28, 2129. Location in Taxonomic Tree . Even so, the limits of PTEs considered safe in plants were not exceeded. https://doi.org/10.1007/s10265-002-0069-z (2003). A key function of calcium oxalate deposits in leaves, the main substance of the composition of druses, is to maintain a low concentration of Ca in the vicinity of the cells of the stoma. In our study, the number of salt glands varied (23 glands/mm2), different from what was observed by Silva et al.46, who found less than 1 gland/mm2, and by Lima et al.45, who cited 2.7 (adaxial surface) and 4.2 (abaxial surface) glands/ mm2 to plants growing in the southern region of Brazil. The present work determined the cold resistance level of L. racemosa and its recovery from cold stress . Technol. Inconspicuous and fragrant white flowers bloom almost year round, occurring as spikes in leaf axils or on the tips of branches. (A,E) CG mangrove; (B,F,H) M mangrove and (D,G) PG mangrove. 3(12), 119. Longer adaxial palisade parenchyma cells were observed in PG (128.779.84m) compared to those in CG (118.4311.60m) (Padj=0.019), but adaxial palisade parenchyma cells in both PG and CG were similar to those found in M (120.688.40m) (Padj>0.05; Fig. Prez-Sirvent, C., Martnez-Snchez, M. J., Martnez-Lpez, S. & Hernndez-Crdoba, M. Antimony distribution in soils and plants near an abandoned mining site. Particulate pollutants deposited on the leaf surface may be absorbed by leaf tissues, resulting in alteration of the chemical structure of epicuticular waxes, thereby causing morphoanatomical damage, such as chlorosis, necrosis, and reduction in photosynthesis and gas exchange40. Buschhaus, C. & Jetter, R. Composition and physiological function of the wax layers coating Arabidopsis leaves: -amyrin negatively affects the intracuticular water barrier. Hortic. Changes in permeability can then result in high water losses through the cuticle44. Most PTE inputs to the bay arrive from rivers, mainly as drainage from highly industrialized and urbanized areas of Sepetiba Bay5,7. Buy Laguncularia racemosa (White Mangrove). The thickness of this tissue ranged from 78.04m in leaves from M to 285.15m in leaves from CG, but no significant difference was found among the three sites (Padj>0.05; Fig. Leaf anatomy of L. racemosa was previously analyzed regarding the description of anatomical features as adaptations to the saline ecosystem45,46,47.
