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...
Movement of genotypes of Ceratocystis fimbriata within and among Eucalyptus pla...
Ferreira, Maria A.; Harrington, Thomas C.; Alfenas, Acelino C.; Mizubuti, Eduardo S. G.Ceratocystis wilt on eucalyptus, caused by Ceratocystis fimbriata, was first recognized in 1997 in the state of Bahia, Brazil, but is now known in five other states and in four other countries. C. fimbriata is a native, soilborne pathogen in some parts of Brazil but we hypothesized that genotypes of the pathogen have been moved among plantations in rooted cuttings collected from diseased trees and within planta...
Species or genotypes? reassessment of four recently described species of the Ce...
Oliveira, Leonardo S. S.; Harrington, Thomas C.; Ferreira, Maria A.; Damacena, Michelle B.; Al-Sadi, Abdullah M.; Al-Mahmooli, Issa H. S.Ceratocystis wilt is among the most important diseases on mango (Mangifera indica) in Brazil, Oman, and Pakistan. The causal agent was originally identified in Brazil as Ceratocystis fimbriata, which is considered by some as a complex of many cryptic species, and four new species on mango trees were distinguished from C. fimbriata based on variation in internal transcribed spacer sequences. In the present study...
