“…In this work, the leaf and root anatomy of the plants were in accordance with previous reports of A. imperialis as well as other species of the Bromeliaceae family (Zorger et al 2019, Martins et al 2020a, Silva et al 2020b, Faria et al 2021. Even though Se modulated the root architecture of A. imperialis plants, this metalloid did not interfere with the roots' anatomical traits.…”

“…Therefore, the decreased values of VI, verified in this work, corresponded to a relative improvement of electron transport to PSI, which was reflected in increased values of ψR0 and φR0. These results may also reflect the increased electrons flux toward the cyclic flow to improve metabolic energy (ATP) to plants (Fang et al 2020). Lower values of ψR0 are associated with reduced PSI activity (Rastogi et al 2019, Faseela et al 2020.…”

“…Together with the roots, they are used for fixation, which justifies the more elaborate character of the trichomes, enhancing the shield-fluid contact area. Thus, it favors water and nutrients' absorption as the Tillandsia species use the trichomes instead of the roots for this function (Faria et al, 2021;Ha et al, 2021;Scatena & Segecin, 2005).…”

“…Most Tillandsia species are epiphytes and adapted to xeric environments and have in their leaves epidermic trichomes capable of absorbing water and nutrients (Faria et al, 2021;Ha et al, 2021;Papini, Tani, Falco, & Brighigna, 2010;Scatena & Segecin, 2005). It is also possible to find species with rupicolous or saxicolous habits (Stefano et al, 2008).…”

Tillandsia L. is the largest genus of the family Bromeliaceae, containing 755 species and seven subgenera. Morphoanatomical studies of leaves provide useful characteristics to phylogenetic, taxonomic, and ecological analyses. This study aims to characterize and compare the leaves of 24 species of the four subgenera of Tillandsia that occur in Bahia and also perform adaptative inferences to environmental responses.The results of the species' morphoanatomical studies were compared through dissimilarity analysis. The species have rosulate leaves with varying lengths and widths. The peltate trichomes present variation in the indument density and the length of their wing and central disk. The stomata are longitudinally distributed in one or both sides of the limb. The mesophyll is dorsiventral and presents aquiferous and chlorophyllic parenchymas. The vascular bundles are collateral and partially covered by fibers, except for Tillandsia linearis. Based on the dissimilarity analysis, it was possible to identify the formation of five groups. Group G1 was composed of T. linearis, which diverged from the other species of the subgenus. Group G2 was formed by the remaining species of the subgenus Phytarrhiza. G3 and G4 presented the species of the subgenus Diaphoranthema and Tillandsia, respectively. Group G5 gathered 11 species of the subgenus Anoplophytum and presented higher variability than the other subgenera. Based on the results, the morphoanatomical characteristics can be used to characterize and group Tillandsia species, besides confirming the morphological variability of these species to the epiphyte habit in different environments, especially xeric ones.

“…Taking into account that holistic characterizations are known to greatly benefit from the use of the widest possible set of different variables, and consequently from the largest possible number of analyses, the pursuit of distinct perspectives and characterization strategies is of the utmost interest to get deeper insight into dynamic vicariant systems. In this line of thought, based on several reports of environmental effects on the composition of epicuticular waxes, ( Hull et al, 1979 ; Shepherd et al, 1995 ; Medina et al, 2004 ; Domínguez et al, 2011 ; Ortúñez and Cano-Ruiz, 2013 ; Rajčević et al, 2014 ; Menzel et al, 2017 ; Xue et al, 2017 ; Sharma et al, 2018 ) as well as on the close link established between the characteristics of epicuticular waxes of many taxa and taxonomic, ecological or evolutive issues, ( Li and Christophel, 2000 ; Versieux et al, 2012 ; Li et al, 2016 ; Mitić et al, 2016 ; Harris et al, 2017 ; Klimko et al, 2018 ; Lindelof et al, 2020 ; Weber and Schwark, 2020 ; Faria et al, 2021 ) we propose in this work an unprecedented strategy to contribute to the study of vicariant phenomena in plant science. This new strategy involves a comprehensive physical–chemical analysis of the surface of plant leaves that strengthens the more usual phylogenetic, biogeographic and ecological approaches.…”

Vicariance Between Cercis siliquastrum L. and Ceratonia siliqua L. Unveiled by the Physical–Chemical Properties of the Leaves’ Epicuticular Waxes

Classically, vicariant phenomena have been essentially identified on the basis of biogeographical and ecological data. Here, we report unequivocal evidences that demonstrate that a physical–chemical characterization of the epicuticular waxes of the surface of plant leaves represents a very powerful strategy to get rich insight into vicariant events. We found vicariant similarity between Cercis siliquastrum L. (family Fabaceae, subfamily Cercidoideae) and Ceratonia siliqua L. (family Fabaceae, subfamily Caesalpinoideae). Both taxa converge in the Mediterranean basin (C. siliquastrum on the north and C. siliqua across the south), in similar habitats (sclerophyll communities of maquis) and climatic profiles. These species are the current representation of their subfamilies in the Mediterranean basin, where they overlap. Because of this biogeographic and ecological similarity, the environmental pattern of both taxa was found to be very significant. The physical–chemical analysis performed on the epicuticular waxes of C. siliquastrum and C. siliqua leaves provided relevant data that confirm the functional proximity between them. A striking resemblance was found in the epicuticular waxes of the abaxial surfaces of C. siliquastrum and C. siliqua leaves in terms of the dominant chemical compounds (1-triacontanol (C30) and 1-octacosanol (C28), respectively), morphology (intricate network of randomly organized nanometer-thick and micrometer-long plates), wettability (superhydrophobic character, with water contact angle values of 167.5 ± 0.5° and 162 ± 3°, respectively), and optical properties (in both species the light reflectance/absorptance of the abaxial surface is significantly higher/lower than that of the adaxial surface, but the overall trend in reflectance is qualitatively similar). These results enable us to include for the first time C. siliqua in the vicariant process exhibited by C. canadensis L., C. griffithii L., and C. siliquastrum.
