Foliar secretory structures in Crotoneae (Euphorbiaceae): diversity, anatomy, and evolutionary significance
(American Journal of Botany, 2018)
Cell wall thickenings and tylosoid: developmental morphology reveals novelties for secretory canals in Protium ovatum (Burseraceae)
(2022-03-01)
We investigated the structure, histochemistry, and ultrastructure of the secretory canals in the vegetative axis of Protium ovatum from a developmental perspective. Samples of roots, stems, and leaves were analyzed using ...
A New Species of Eriosema (Leguminosae, Papilionoideae, Phaseoleae) from Mato Grosso do Sul, Brazil, with a Secretory Structure Novel to the Genus
(Magnolia Press, 2016-06-01)
Eriosema grearii, a new species for the genus (Leguminosae, Papilionoideae, Phaseoleae, Cajaninae), is described and illustrated. Similar to E. heterophyllum, it differs from it morphologically by the free (vs. joined) ...
Structure and function of secretory glochids and nectar composition in two opuntioideae (Cactaceae) species
(2020-01-01)
Cactaceae exhibit highly modified spines that are considered to be extrafloral nectaries (EFNs). Despite their ecological and taxonomical relevance in this family, little is known on their structure and function. We have ...
Developmental and structural features of secretory canals in root and shoot wood of Copaifera langsdorffii Desf. (Leguminosae-Caesalpinioideae)
(Springer, 2009-10-01)
Copaifera langsdorffii Desf., popularly known as copaiba, is an oleoresin-producing tree has been over-exploited in Brazil by the pharmaceutical, cosmetic and varnish industries. Despite the long history of the use of this ...

Secretory structures of the Adesmia clade (Leguminosae): Implications for evolutionary adaptation in dry environments
(Elsevier B.V., 2021-02-01)
The Dalbergioid Adesmia Glade comprises Adesmia DC., Amicia Kunth, Nissolia Jacq., Poiretia Vent., and Zornia J. F. Gmel., all predominantly South American genera except for Zornia which has a pantmpical distribution. These ...
Comparative study of the ultrastructure and secretory dynamic of hypopharyngeal glands in queens, workers and males of Sceptotrigona postica latreille (Hymenoptera, Apinae, Meliponini)
(Inst Histol Embriol-conicet, 2000-04-01)
The secretory cycle of hypopharyngeal glands (HPGs) in Scaptotrigona postica resembles that of Apis mellifera: in newly emerged workers the HPGs are in prefunctional state, their maximum development happens in the nurse ...
