Journal Article 2000

Autor: Ojeda, S Verdier, Valérie

Cassava bacterial blight, caused by Xanthomonas axonopodis pv. manihotis (Xam), is a particularly destructive disease in South America and Africa. Because of quarantine procedures, international exchange of cassava germplasm is limited and occurs through true seeds or material propagated in vitro...

Cassava bacterial blight, caused by Xanthomonas axonopodis pv. manihotis (Xam) is a destructive disease occurring in most cassava growing-areas. Although Colombian isolates of Xam differ in DNA polymorphism and pathogenicity, no suitable host differentials have been identified to demonstrate phys...

DNA polymorphism and variation in virulence of Xanthomonas axonopodis pv. manihotis (Xam), the causal agent of cassava bacterial blight, were studied within a pathogen population from Venezuela. Collections were made in several fields at different sites within an edaphoclimatic zone where cassava...

We evaluated cassava bacterial blight (CBB) infection in an pair-cross population of 150 individuals derived from an intra-specific cross between two non-inbred cassava (Manihot esculenta Crantz) lines. The replicated trials were carried out in the field under high disease pressure over two conse...

Cassava bacterial blight, caused by Xanthomonas axonopodis pv. manihotis, is of significant concern wherever cassava is grown. The movement of infected, asymptomatic stems is a major means of pathogen dispersal. A reliable and sensitive diagnostic procedure is necessary for the safe movement of c...

Xanthomonas oryzae pathovar oryzae (Xoo) and X. oryzae pv. oryzicola (Xoc) cause bacterial diseases in rice: leaf blight and leaf streak, respectively. Although both the Asian and the African strains of Xoo induce similar symptoms, they are genetically different, with the African Xoo strains bein...

Cassava is an important crop in Colombia grown on approximately 196 000 hectares of land. One of the limiting factors for production is Xanthomonas axonopodis pv. manihotis (Xam). The geographical distribution of the disease and its incidence are described for different ecological zones of Colomb...
