“…The cuticle is separated from the outer cap cell wall, resulting in the formation of a salt collecting Chamber (Fig. 12.4b) or cuticular cavity which is similar in the species of Salsola (both annual and perennial), Aeluropus litoralis, Eremopyrum orientale, Spartina, a b Cynodon and Distichlis (Thomson 1975) and probably represents a temporary collecting compartment where secreted salts accumulate prior to elimination from the leaf. The ions seem to be compartmentalized in small vacuoles and transported to the cuticular cavity, prior to exclusion from the vegetative and reproductive organs either through cuticular pores or by rupture of the cuticle (Yordoan and Kruger 1998; Naidoo and Naidoo 1998;Rozema and Riphagen 2007).…”

Plant Adaptation and Phytoremediation

Phytoremediation, the use of plants to extract, sequester, and/or detoxify pollutants through biological processes is an effective, in situ, non-intrusive, lowcost, ecologically friendly, socially accepted technology to remediate polluted soils. Crystalline to fibrillar wax formations, appressed to surfaces of guard cells appear to originate from guard cells in the vicinity of the stomatal aperture. Formations may arise from evaporation of plant water at the interface between stomatal antechambers and substomatal cavities, leaving salt ions behind to precipitate. Many questions remain unanswered regarding their ecological and physiological significance as well as their occurrence and prevalence in both time and space. Such functions would be of considerable adaptive value in the light of their possible relationships to the impact of pollutants. An attempt has been made here to address these questions by analysing the morphology of salt glands and intracellular salt crystals using SEM micrographs of Salsola, Eremopyrum, Aeluropus litoralis, Tamarix and other desert plants.

“…Rodrigues et al (2002) avaliaram a situação em folhas do manguezal submetido às atividades petrolíferas e encontraram quantidades glandulares maiores e menores, com relação à área não impactada. Thompson (1975) atribui às glândulas de sal de plantas do gênero Avicennia (Avicenniaceae) a função de manutenção do equilíbrio osmótico, estando as quantidades sujeitas à alterações de acordo com o teor salino do ambiente. Drennan & Berjak (1982) (Lamberti 1969;Macêdo 1983), tal afirmação não pôde ser confirmada no presente estudo.…”

Enviado em outubro de 2007, aprovado em novembro de 2010. RESUMO:Atualmente, os ecossistemas conhecidos como manguezais têm sido foco das mais variadas pesquisas, envolvendo estudos de fauna, flora, ecologia, entre outros. A demanda por conhecimentos sobre esse ecossistema provém, principalmente, da necessidade de se compreender as conseqüências das atuais e futuras ações humanas. No presente estudo, objetivou-se caracterizar a anatomia e comparar, juntamente com os perfis químicos, folhas de Avicennia schaueriana e Rhizophora mangle, provenientes de manguezais impactados (estuário do município de Santos) e não impactados (estuário do município de Peruíbe) do litoral de São Paulo, correlacionando as possíveis diferenças com fontes de impacto ambiental de cada área. Para A. schaueriana não foram observadas diferenças significativas com relação aos aspectos anatômicos. Já para R. mangle, observou-se maior densidade estomática em folhas do ambiente impactado, bem como aumento na espessura do parênquima paliçádico, diminuição do parênquima esponjoso e expansão da região dos feixes vasculares, na nervura central. Com relação à análise química, os grupos dos compostos apontados nos perfis cromatográficos diferem em quantidade e qualidade para R. mangle e apenas em quantidade para A. schaueriana.

“…Salt glands function to eliminate salts to the outside of the plant or within the plant into vacuoles (Thomson, 1975). Structurally there are three types of salt glands described (Thomson, 1975); the bicellular glands of the grasses, the bladder cells of the Oxalidaceae, Chenopodiaceae and Mesembryanthemaceae and the multicellular gland found only in dicotyledons.…”

Regardless of the fact that the structure of salt glands varies greatly among different species, it is, very similar in plants within the same family or genus (Salama et al, 1999).…”

Background: The genus Plumbago distributed in warm tropical regions throughout the world is the largest genus in Plumbaginaceae. Medicinal plants are characteristic to the genus Plumbago and are cultivated and utilized worldwide. Plumbago auriculata Lam. is common in South Africa and is often cultivated for its ornamental and medicinal uses throughout the world. Materials and Methods: A comprehensive review of the genus Plumbago with focus on Plumbago auriculata was carried out and information was gathered using scientific publications, conference proceedings, the internet and books. Articles based on the morphology, pharmacological and medicinal uses of Plumbago auriculata was analysed thoroughly. Results: Plumbago auriculata plant parts posses a wide range of phytochemicals with plumbagin being the marker compound showing various pharmacological activities. Different plant parts are claimed to be used for the treatment of human and animal ailments, however they do exhibit toxic properties and need to be administered with caution. Salt secreting glands and trichomes are characteristic of Plumbaginaceae. Conclusion: This study reveals new insights on the genus Plumbago and the potential use of species in the genus as medicinal plants. Plumbago auriculata possess the bioactive compound plumbagin and secondary metabolites, thus, it is of high medicinal importance. P. auriculata is a poorly nor favourite studied species in the genus Plumbago and further research needs to be carried out to explore specific details of the species.
