Abstract
Sixteen isolates of Fusarium sp. were isolated from
robusta coffee trees in Uganda with symptoms of vascular
wilt and characterized based on morphology and partial
DNA sequences of translation elongation factor 1-alpha
(ef) and beta-tubulin (bena). Fusarium sp. isolates
from robusta and arabica coffee trees in Zimbabwe,
New Caledonia and Ethiopia were also characterized.
Phylogenetic analyses indicated that these isolates
represent a new species lineage in the African clade of the
Gibberella fujikuroi species complex (GFC). The species
most commonly associated with this disease, Fusarium
xylarioides, is not a member of GFC, suggesting that
recent outbreaks of vascular wilt in Uganda may have
been caused by a new pathogen
