Outer cell wall structure and the secretion mechanism of colleters of Bathysa n...
Miguel,Emilio de Castro; Pireda,Saulo; Barros,Claudia Franca; Zottich,Umberto; Gomes,Valdirene Moreira; Miguens,Flavio Costa; Cunha,Maura DaABSTRACT Secretory structures are formed by many types of plants and are present on numerous different organs. Among the many types of known secretory structures, colleters are predominant on plants of the Rubiaceae. One remarkable characteristic of secretory tissues is the export of exudates; however, the precise mechanism involved in this process is still unclear. To better understand the mechanisms of exudat...

Miguel,Emilio de Castro; Klein,Denise Espellet; Oliveira,Marco Antonio de; Cunha,Maura da(Ultrastructure of secretory and senescence phase in colleters of Bathysa gymnocarpa and B. stipulata (Rubiaceae)). Colleters are secretory structures formed by a parenchymatic axis with vascular bundles, bound by a layer of secretory palisade-like epidermis. Some studies regarding the structure of colleters have focused on secretory cells structure, but not distinguished the secretory and senescent phases. Gen...
