Abstract: ABSTRACT(Mucilage-secreting structures of Hibiscus pernambucensis Arruda (Malvaceae): distribution, morphoanatomical and histochemical characterization). This work studied the mucilage-secreting structures of Hibiscus pernambucensis using light and scanning electron microscopy. Known as guaxima-do-mangue, algodão-do-brejo and embira-do-mangue, this species is a native shrub that occurs in mangrove and restinga along the Brazilian coast, and is important in the production of textile fibers and cellulose, provid… Show more

“…In the mesophyll, cells with large dimensions, and a single cell occupying the space between the adaxial and abaxial epidermal surfaces (found in A. grandifolium ) are described in the literature as a secretion structure of petals (Bouchet & Deysson ; Rocha et al . ). The secreted product is mucilage, which has taxonomic significance for the Malvaceae family (Scott & Bystrom ; Pimentel et al .…”

“…The non-occurrence of proteins in the secretions exuded by the colleters seems to be common for species of the subfamily Myrtoideae and has been previously reported (Silva et al 2012). The presence of proteins in the colleter secretions was observed in families such as Apocynaceae (Leite 2012), Rubiaceae (Castro et al 2006), Caryocaraceae (Paiva & Machado 2006) e Malvaceae (Rocha et al 2011), and are understood as a defense mechanism against pathogens and herbivores (Klein et al 2004;Demarco 2005;Leite 2012).…”

“…Due to their morphological diversity, the colleters has been successfully used in taxonomic studies involving several botanical families (Woodson & Moore 1938;Thomas 1991;Rio et al 2002Simões et al 2006;Silva et al 2012). In addition, they have ecological importance because of their function of protection against dissection and pathogen attack (Lersten 1974;Mangalan et al 1990;Miguel et al 2009;Mayer et al 2011;Rocha et al 2011).…”

“…The retention of water by mucilage present in the intercellular spaces, cell walls, and vacuoles in M. flexuosa constitutes a continuous path of water retention within the plant body. Mucilage is very useful to plants, particularly under high evapotranspiration rate conditions (Morse, 1990; Arend et al, 2008) as it increases resistance to water losses in soil–plant–atmosphere systems (Ghanem et al, 2010; Rocha et al, 2011). Plant species belonging to diverse taxonomic groups, such as aquatic macrophytes and coastal algae, have developed mechanisms to adapt to daily or seasonal fluctuations in soil and air humidity (Clifford et al, 2001; Ghanem et al, 2010).…”
