Gentianaceae; adults; apical meristems; electron microscopy; endoplasmic reticulum; head; leaves; ontogeny; peduncle; polysaccharides; programmed cell death; secretion; synapomorphy; trichomes
Abstract:
... Colleters are secretory structures involved in the protection of young and developing plant organs. Although the presence of colleters in Gentianales is described as a synapomorphy, studies on the morphofunctionality of colleters and the mechanisms underlying the synthesis and release of colleter secretion in Gentianaceae are scarce. Here, we described the ontogeny and the morphological and functi ...

Bonnetiaceae; Calophyllaceae; Clusia; Hypericaceae; Podostemaceae; benzophenones; latex; ovules; quinones; resins; secretion; synapomorphy; xanthones
Abstract:
... The Clusioid clade is quite diverse, encompassing the five families Clusiaceae, Bonnetiaceae, Calophyllaceae, Hypericaceae, and Podostemaceae. However, its members have important synapomorphies, such as the presence of xanthones, polyisoprenylated benzophenones, and quinones, as well as schizogenous secretory ducts and cavities, and tenuinucellate ovules. Owing to the milky appearance of the exuda ...

3. Diversity of leaf secretory structures in five Neotropical genera of Primulaceae: ecological aspects and evolutionary significance

Botany 2019 v.97 no.1 pp. 35-51
ISSN:

Subject:
Primulaceae; environmental factors; fluorescence microscopy; leaves; meristems; secretion; synapomorphy; trichomes
Abstract:
... Many species of Primulaceae have chemical or medicinal importance, directly related to the presence of an important set of secretory structures distributed throughout the entire plant. Such structures are not only relevant in a pharmaceutical context, but also for taxonomic, systematic, and evolutionary studies within the family. Despite this, studies of the secretory structures in Primulaceae are ...

Subject:
Blattodea; Termitidae; exocrine glands; secretion; synapomorphy
Abstract:
... Termites have developed many exocrine glands, generally dedicated to defence or communication. Although a few of these glands occur in all termite species, or represent synapomorphies of larger clades, others are morphological innovations of a single species, or a few related species. Here, we describe the nasus gland, a new gland occurring at the base of the nasus of Angularitermes soldiers. The ...
