Genetic variation, morphology and pathogenicity of Ceratocystis fimbriata on He...
Valdetaro, Denise C. O. F.; Oliveira, Leonardo S. S.; Guimarães, Lúcio M. S.; Freitas, Rodrigo G.; Alfenas, Acelino C.; Ferreira, Maria A.Ceratocystis fimbriata causes diseases on a wide variety of plants in Brazil, including rubber tree (Hevea brasiliensis), on which it causes gray mold or moldy rot on tapping panels affecting latex yield. However, C. fimbriata isolated from rubber tree have not been critically studied. Phylogenetic analyses of sequences of ITS rDNA and a mating type gene placed rubber tree isolates from Acre and Bahia among Bra...
A host specialized form of Ceratocystis fimbriata causes seed and seedling blig...
Valdetaro, Denise C. O. F.; Oliveira, Leonardo S. S.; McNew, Douglas L.; Pimenta, Lucas V. A.; Gonçalves, Rivadalve C.; Schurt, Daniel A.Ceratocystis fimbriata Ellis & Halsted recently was recorded causing seed and seedling blight on Carapa guianensis Aubl. (andiroba), a tree species native to the Amazon Rainforest and prized for its valuable timber and medicinal seed oil. C. fimbriata more commonly causes wilt type diseases in woody hosts, especially on non-native host trees. However, on andiroba the disease occurs on seedlings and seeds, affec...
Ceratocystis fimbriata isolates on Mangifera indica have different levels of ag...
Oliveira, Leonardo S. S.; Damacena, Michelle B.; Guimarães, Lúcio M. S.; Siqueira, Dalmo L.; Alfenas, Acelino C.Mango is amongst the most exported fruits worldwide and the mango tree has been cultivated in many countries with tropical and subtropical climates. Currently, Ceratocystis wilt caused by Ceratocystis fimbriata is among the most important diseases on mango tree. Planting of resistant genotypes is the best strategy for disease control. In the selection of resistant plants a highly aggressive isolate should be us...
