Purification, biochemical characterization and antifungal activity of a new lip...
Zottich, Umberto; Cunha, Maura da; Carvalho, André O.; Dias, Germana Bueno; Silva, Nádia C.M.; Santos, Izabela S.; Nacimento, Viviane V. doBackground: A growing number of cysteine-rich antimicrobial peptides (AMPs) have been isolated from plants and particularly from seeds. It has become increasingly clear that these peptides, which include lipid transfer proteins (LTPs), play an important role in the protection of plants against microbial infection. Methods: Peptides from Coffea canephora seeds were extracted in Tris–HCl buffer (pH 8.0), and chro...
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 daSecretory structures are formed by many types of plants and are present on numerous diff erent 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 exudate extern...

Rabelo, Guilherme Rodrigues; Marques, Jonas de Brito Campolina; Zottich, Umberto; Dias, Germana Bueno; Miguel, Emilio de Castro(Leaf structure, microanalysis and characterization of the latex protein profile of Pachystroma longifolium (Nees) I.M. Jonhst. (Euphorbiaceae) in a seasonally dry Atlantic Forest). Pachystroma longifolium is an evergreen species of Euphorbiaceae that occurs in tabuleiro forest, a type of lowland Atlantic Forest. The site chosen for this study was a fragment of tabuleiro forest that has a history of being selec...
