A utilização de elicitinas no combate contra Phytophthora cinnamomi na doença d...
Cravador, A.; Medeira, C.; Maia, I.; Moreira, A. C.; Candeias, I.; Melo, Eduardo P.; Sousa, NelsonPhytophthora cinnamomi e P. cambivora são considerados os agentes patogénicos da doença da tinta do castanheiro. Estes agentes invadem e destroem o sistema radicular, levando à morte das árvores e a importantes perdas económicas. O declínio do montado tem sido associado a vários agentes patogénicos, pragas e factores abióticos. Phytophthora cinnamomi tem sido referido como um potencial agente patogénico do sobr...
Involvement of the beta-cinnamomin elicitin in infection and colonisation of co...
Cravador, A.; Horta, M.; Caetano, P.; Medeira, C.; Maia, I.The virulence of two wild type (PA45 and PA37) and two genetically modified (13C: hygromycin resistant; FATSS: hygromycin resistant and β-cin knock-down) Phytophthora cinnamomi strains towards cork oak (Quercus suber) was assessed via a quantitative evaluation of disease symptoms arising from a soil infestation assay, and by a istological analysis of root colonization. Comparison of virulence, as expressed by ...
Exposition of cork oak roots to cryptogein reduced the Infection by Phytophtora...
Maia, I.; Medeira, C.; Candeias, I.; Moreira, A. C.; Melo, Eduardo P.; Cravador, A.The oomycete P. cinnamomi has been described as strong contributing factor to the decline of cork oak and holm oak stands occurring in the Iberian Peninsula. There are no eradication methods available against this pathogen.
Quercus suber infected by Phytophthora cinnamomi: effects at cellular level of ...
Maia, I.; Medeira, C.; Melo, Eduardo P.; Cravador, A.Phytophthora cinnamomi has been reported to be regularly associated with cork and holm oak decline. This oomycete secretes elicitins, a group of unique highly conserved pr oteins that can enhance plant defence reactions.
Studies on the association of the Quercus suber decline disease with Phytophtho...
Moreira, A. C.; Medeira, C.; Maia, I.; Quartin, V.; Matos, Mª Céu; Cravador, A.In Portugal, the decline disease has been described in evergreen oaks (Quercus suber L. and Q.ilex subsp. rotundifolia Lam.) since the end of the 19th century. The mortality of these species affects, particularly the central and southern regions of the country, being one of the most severe forest problems. Phytophthora cinnamomi Rands is the main pathogen responsible for the cork and holm oak mortality in Portu...
