The survival of Xanthomonas campestris pv. musacearum (Xcm), the cause of banana bacterial wilt disease in soil and infected banana debris was investigated. Viable cells of the pathogen were estimated on culture medium. The survival of the pathogen in soil was influenced by soil moisture and soil treatment. The survival period of Xcm was reduced 3 times(More)
Xanthomonas wilt, caused by Xanthomonas campestris pv. musacearum has, since 2001, become the most important and widespread disease of Musa in East and Central Africa. Over the past decade, new research findings and especially feedback from small-scale farmers have helped in fine-tuning Xanthomonas wilt control options. During the initial years of the(More)
A PCR-based system was developed to reliably and robustly identify group I and II members of the genus Xanthomonas. Primer sets developed from three gene targets namely fyuA, ITS and gumD were evaluated in the study. Primer sets were evaluated using DNA extracted from 45 Xanthomonas strains representing 25 species broadly covering the genus. Fifteen(More)
Banana is an important staple food crop feeding more than 100 million Africans, but is subject to severe productivity constraints due to a range of pests and diseases. Banana Xanthomonas wilt caused by Xanthomonas campestris pv. musacearum is capable of entirely destroying a plantation while nematodes can cause losses up to 50% and increase susceptibility(More)
Africa is among the continents where the battle over genetically modified crops is currently being played out. The impact of GM in Africa could potentially be very positive. In Uganda, researchers have developed transgenic banana lines resistant to banana Xanthomonas wilt. The transgenic lines expressing hrap and pflp can provide a timely solution to the(More)
Black Sigatoka disease, caused by Pseudocercospora fijiensis is a serious constraint to banana production worldwide. The disease continues to spread in new ecological niches and there is an urgent need to develop strategies for its control. The high osmolarity glycerol (HOG) pathway in Saccharomyces cerevisiae is well known to respond to changes in external(More)
Xanthomonas campestris pv. musacearum (Xcm) causing the banana Xanthomonas wilt (BXW) disease has been the main xanthomonad associated with bananas in East and Central Africa based on phenotypic and biochemical characteristics. However, biochemical methods cannot effectively distinguish between pathogenic and non-pathogenic xanthomonads. In this study,(More)
