Isometamidium chloride has remained a very important prophylactic and therapeutic drug against trypanosomosis in cattle since its introduction into the market in the 1950s with, unfortunately, a concomitant development of resistance in trypanosomosis endemic areas. Amplified Fragment Length Polym...

Cassava is one of the main carbohydrate sources in the tropics, and it has worldwide importance as basic food for millions of persons in America and Africa. This root crop is affected by cassava frog skin disease that in Colombia produces yield losses of almost 90%. A phytoplasma was associated w...

Cassava mosaic disease (CMD) is the most-important disease of cassava (Manihot esculenta) in Africa, and is a potential threat to Latin American (LA) cassava production. Although this viral disease is still unknown in LA, its vector – the whitefly – has recently been found. The disease is best co...

Cassava (Manihot esculenta) is a major food staple for nearly 600 million people in Africa, Asia, and Latin America. Major losses in yield result from biotic and abiotic stresses that include diseases such as Cassava Mosaic Disease (CMD) and Cassava Bacterial Blight (CBB), drought, and acid soils...

The application of biotechnology tools has made it possible to make significant advances in the detection of pathogens and in the study of the genetic variability of pathogen populations. As a result, adequate disease management strategies can be planned, and disease resistance markers for plants...

A genetic map was constructed with specific PCRs, DALPs and AFLPs using F8-generation sunflower recombinant inbred lines. RI lines generated from a F2 population of one cross between the two cultivated inbred lines HA89 (maintainer for Pet1 CMS) and LR4 (restorer for Pet1 CMS) were used. A total ...
