Geographical Differentiation of the Population of Xanthomonas axonopodis pv. manihotis in Colombia.
Analyses of DNA polymorphism and virulence variation were used to evaluate the population structure of Xanthomonas axonopodis pv. manihotis, the pathogen causing cassava bacterial blight in Colombia. We collected strains from the major cassava-growing regions which can be grouped into different edaphoclimatic zones (ECZs) according to environmental conditions, production constraints, and econom...
متن کاملGenetic structure and population dynamics of Xanthomonas axonopodis pv. manihotis in Colombia from 1995 to 1999.
Restriction fragment length polymorphisms (RFLPs) were used to study the population genetics and temporal dynamics of the cassava bacterial pathogen Xanthomonas axonopodis pv. manihotis. The population dynamics were addressed by comparing samples collected from 1995 to 1999 from six locations, spanning four different edaphoclimatic zones (ECZs). Forty-five different X. axonopodis pv. manihotis ...

متن کاملAFLP fingerprinting: an efficient technique for detecting genetic variation of Xanthomonas axonopodis pv. manihotis.
Xanthomonas axonopodis pv. manihotis (Xam) is the causative agent of cassava bacterial blight (CBB), a worldwide disease that is particularly destructive in South America and Africa. CBB is controlled essentially through the use of resistant varieties. To develop an appropriate disease management strategy, the genetic diversity of the pathogen's populations must be assessed. Until now, the gene...
متن کاملPhysiological Studies on Xanthomonas axonopodis Pv Manihotis (Xam) Strains Isolated in Nigeria
Xanthomonas axonopodis pv manihotis (Xam) is the causal agent of cassava bacterial blight (CBB) worldwide. To develop a well-organized disease management policy in a country, the diversity of pathogens population must be known. The bacterial populations of Xanthomonas axonopodis pv manihotis (Xam) obtained as flora cassava leaves and stems, in Nigeria were characterized by their biochemical and...
