| gibberella xylarioides sensu lato from coffea canephora: a new mating population in the gibberella fujikuroi species complex. | gibberella xylarioides heim & saccas (presumed anamorph, fusarium xylarioides steyaert) is the causal agent of coffee wilt disease, an economically important tracheomycosis in africa. in vitro crosses carried out with congolese, ugandan, and tanzanian single-ascospore/conidial isolates originating from diseased coffea canephora/excelsa demonstrated a heterothallic mating system, controlled by a single locus with two alleles, mat-1 and mat-2. compatible isolates produced fertile perithecia within ... | 2005 | 16332836 |
| gibberella xylarioides (anamorph: fusarium xylarioides), a causative agent of coffee wilt disease in africa, is a previously unrecognized member of the g. fujikuroi species complex. | tracheomycosis or coffee wilt has emerged as a major disease of robusta coffee in uganda in the past 10 years. coffee wilt historically has been associated with fusarium xylarioides steyaert (teleomorph gibberella xylarioides heim and sacc.), a species that has been classified as a member of fusarium section lateritium. we investigated the molecular phylogenetics of fusarial coffee wilt isolates by generating partial dna sequences from two protein coding regions, translation elongation factor 1- ... | 2005 | 16389971 |
| current knowledge of coffee wilt disease, a major constraint to coffee production in africa. | abstract coffee is vital to the economy of east and central africa, providing a major source of foreign exchange earnings and, as a cash crop, supporting the livelihoods of millions involved in cultivation, processing, marketing, and export. coffee wilt disease (cwd), attributed to gibberella xylarioides (fusarium xylarioides), has caused losses to coffee production in africa since 1927 but has been largely contained through the use of host resistance and in some instances wide-scale sanitation ... | 2006 | 18943187 |
