Los genes de resistencia se buscaron mediante dos estrategias. La primera, por medio de hibridización con sondas de maíz y arroz, utilizando RFLP. La segunda consistió en la amplificación de regiones conservadas de ADN, con cebadores degenerados NBS y Pto kinasa, en tres genotipos de yuca resiste...
Cassava cultivars often have poor resistance to biotic stresses and lack good quality traits. Wild species of cultivated crops have frequently been used as an important source of genetic diversity. Cassava breeders are becoming increasingly interested in incorporating genes of wild relatives. In ...
En este artículo se revisa el estado del conocimiento sobre el metabolismo del almidón en las plantas superiores y específicamente los mecanismos de control y regulación de las rutas de síntesis y degradación. Se considera que para obtener almidones, mediante manipulación genética, es necesario ...
Breeding for resistant genotypes is the best strategy to offset the destructive effects of cassava mosaic disease (CMD) and cassava bacterial blight (CBB). Two sets of diallel parents were selected for the forest and the savannah ecological zones in Ghana based on good levels of resistance to CMD...
Cassava bacterial blight (CBB), caused by Xanthomonas axonopodis pv. manihotis (Xam), is a major disease of cassava (Manihot esculenta Crantz) in Africa and South America. Planting resistant varieties is the preferred method of disease control. Recent genetic mapping of an F1 cross (TMS 30572 × C...
Cassava is one of the most planted tuber crops in the tropical world. The importance of cassava is growing as a food security crop in sub Saharan Africa, where malnutrition is a menace. However, a major hindrance in the fast improvement of the crop is the long generational cycle of cassava and po...
Cassava (Manihot esculenta) is a tropical crop that is grown in Africa, Latin America and Southeast Asia. Cassava was introduced from Latin America into West and East Africa at two independent events. In Uganda a serious threat to cassava's survival is the cassava mosaic disease (CMD). Uganda has...
