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 Saccharomy...
Diamondback moth (DBM), Plutella xylostello L., is the main pest limiting cabbage production in Benin. Inthe search for biological agents to control the pest, eight isolates of the entomopathogenic fungiBeauveria bassiana and Metarhizium anisopliae indigenous to Benin were screened for virulence ...
Seed transmission of Xanthomonas campestris pv. vignicola was investigated to ascertain the importance of seed as a primary source of inoculum for bacterial blight disease in cowpea. The study was carried out using seeds of five cowpea varieties (TVx 12349, IT86D-721, IT82D-889, Ife Brown and TVx...
Studies on the effect of different storage conditions on the virulence of NPV revealed that samples stored in earthen pot and at room temperature maintained efficacy up to four months and after that virulence started decreasing. This decreased efficacy of samples stored under room temperature may...
Simple sequence repeat (SSR) markers were used to classify 116 isolates of Phakopsora pachyrhizi, the cause of soyabean rust, collected from infected soyabean leaves in four agroecological zones in Nigeria. A high degree of genetic variation was observed within the sampled populations of P. pachy...
Colletotrichum lindemuthianum is a highly variable pathogen of common beans that easily overcomes resistance in cultivars bred with single-gene resistance. To determine pathogenic variability of the pathogen in Uganda, samples of common bean tissues with anthracnose symptoms were collected in eig...
Cassava (manihot esculenta Crantz), a major food crop in tropical lowlands, is susceptible to many pathogens that decrease the yields. The most common biotic constraint to its production worldwide is Cassava Bacterial Blight (CBB) caused by Xanthomonas axonopodis pv. Manihotis (Xam).
Mycoplasmas are the smallest free-living organisms and cause a number of economically important diseases affecting humans, animals, insects, and plants. Here, we demonstrate that highly virulent Mycoplasma mycoides subspecies capri (Mmc) can be fully attenuated via targeted deletion of non-essent...
