A metabolome analysis and the immunity of Phlomis purpurea against Phytophthora...
Neves, Dina; Figueiredo, Andreia; Maia, Marisa; Laczko, Endre; Pais, Maria Salomé; Cravador, AlfredoPhlomis purpurea grows spontaneously in the southern Iberian Peninsula, namely in cork oak (Quercus suber) forests. In a previous transcriptome analysis, we reported on its immunity against Phytophthora cinnamomi. However, little is known about the involvement of secondary metabolites in the P. purpurea defense response. It is known, though, that root exudates are toxic to this pathogen. To understand the invol...

De novo assembly of Phlomis purpurea after challenging with Phytophthora cinnamomi
Baldé, Aladje; Neves, Dina; García-Breijo, Francisco J; Pais, Maria S; Cravador, A.Background Phlomis plants are a source of biological active substances with potential applications in the control of phytopathogens. Phlomis purpurea (Lamiaceae) is autochthonous of southern Iberian Peninsula and Morocco and was found to be resistant to Phytophthora cinnamomi. Phlomis purpurea has revealed antagonistic effect in the rhizosphere of Quercus suber and Q. ilex against P. cinnamomi. Phlomis purpurea...
Structure, anti-Phytophthora and anti-tumor activities of a nortriterpenoid fro...
Mateus, Maria Da Conceição; Neves, Dina; Dacunha, Bruno; Laczko, Endre; Maia, Cristiana; Teixeira, Rúben; Cravador, AlfredoTo investigate bioactive compounds potentially involved in the biotic interactions exhibited by Phlomis purpurea (Lamiaceae) in rhizospheres infested with Phytophthora cinnamomi, the plant rhizome was chemically analysed. The nortriterpenoid (175)-2 alpha,3 alpha,11 alpha,23,24-pentahydroxy-19(18 -> 17)-abeo-28-norolean-12-en-18-one, was isolated and its structure was elucidated by comprehensive spectroscopic a...
