Plant disease resistance genes (R genes) show significant similarity amongst themselves in terms of both their DNA sequences and structural motifs present in their protein products. Oligonucleotide primers designed from NBS (Nucleotide Binding Site) domains encoded by several R-genes have been us...

El añublo del arroz causado por Pyricularia grisea (Magnaporthe grisea) es el principal limitante de la producción en Colombia. La perdida de la resistencia ocurre en penodos de uno a tres años, con la excepción de los cultivares Oryzica Llanos 5 liberado en 1989 y Fedearroz 50 liberado en 1998. ...

Con el objetivo de evaluar bajo condiciones de invernadero genotipos de plátano y banano frente a poblaciones de Mycosphaerella fijiensis Morelet de diferente virulencia y origen, se estableció una colección de 125 aislamientos monospóricos obtenidos en 10 departamentos de Colombia. Se selecciona...

El añublo ô quemazón del arroz, causado por el hongo P. grisea (Sacc), es la enfermedad más limitante del cultivo en todo el mundo. La resistencia varietal ha sido y continua siendo la base para el control de la pyricularia, sin embargo, ésta resistencia se pierde rápidamente debido al surgimient...

Common bacterial blight (CBB) is the most serious bacterial disease of common bean in Uganda. It causes severe yield losses of up to 62%. Genetic resistance is the most effective option for controlling CBB in smallholder common bean production systems. This study was carried out to determine the ...

The effectiveness of protein supplementation and genetic selection to enhance the resistance of periparturient Merino ewes to infection from gastrointestinal parasites was tested in a replicated grazing experiment. One hundred and twenty ewes from lines selected for increased resistance (R) to Ha...
Resistance and resilience to naturally acquired gastro-intestinal (GI) nematode parasite infections (predominantly Haemonchus contortus) were studied in 1785 lambs born over six lambings (1991 to 1996) consisting of 212 Red Maasai, 311 Dorper and 1262 crossbred (Red Maasai-Dorper) lambs in the su...

Cassava is an important crop in Colombia grown on approximately 196 000 hectares of land. One of the limiting factors for production is Xanthomonas axonopodis pv. manihotis (Xam). The geographical distribution of the disease and its incidence are described for different ecological zones of Colomb...
