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...
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 کاملPolyphasic characterization of xanthomonas strains from onion.
ABSTRACT Xanthomonas leaf blight has become an increasingly important disease of onion, but the diversity among Xanthomonas strains isolated from onion is unknown, as is their relationship to other species and pathovars of Xanthomonas. Forty-nine Xanthomonas strains isolated from onion over 27 years from 10 diverse geographic regions were characterized by pathogenicity to onion and dry bean, fa...
متن کاملVegetative compatibility and rep-PCR DNA fingerprinting groups of Fusarium solani isolates obtained from different hosts and their pathogenicity
Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...
