There was considerable interest and discussion related to the progress made in both the Australian and New Zealand breeding schemes that assist commercial ram breeders to incorporate selection for resistance to gastrointestinal nematode parasites into their breeding programmes along with selectio...
Susceptible A/J and more resistant C57BL/6J mice were infected with Plasmodium chabaudi chabaudi 54X, P.c. chabaudi AS and Plasmodium chabaudi adami 408XZ. As expected, most C57BL/6J mice survived the infections with the different isolates. But in contrast to previous observations, not all A/J ...

A study was carried out from 1992 to 1996 to compare the resistance to naturally acquired gastro intestinal (GI) nematode parasite infections (predominantly Haemonchus contortus) of Galla and Small East African goats in the sub humid coastal region of Kenya. A total of 204 Galla and 349 Small Eas...

A study was conducted to determine the extent of genetic diversity among African cassava (Manihot esculenta Crantz) accessions resistant to the cassava mosaic virus disease (CMD), using simple sequence repeat (SSR) markers. The accessions included a breeding stock (clone 58308), five improved lin...

La antracnosis causada por Colletotrichum lindemuthianum puede llegar a generar pérdidas hasta del 95% de la producción en fríjol (Phaseolus vulgaris L.), por eso es considerada una de las enfermedades más limitantes. Con el presente trabajo se inició un programa de mejoramiento utilizando selecc...

Se evaluó la resistencia de los padres y las progenies de la familia de yuca K (M Nga 2 x CM 2177-2), a Phytophthora tropicalis. Además de los parentales se inocularon raíces frescas de 69 individuos de la familia K. Con la evaluación fenotípica y con base en las mapas moleculares de M Nga 2 (Mad...

Background and Aims: Aluminium (Al) resistance in common bean is known to be due to exudation of citrate from the root after a lag phase, indicating the induction of gene transcription and protein synthesis. The aims of this study were to identify Al-induced differentially expressed genes and to ...

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...

Rice yellow mottle virus (RYMV) causes high losses to rice production in Africa. Several sources of varietal high resistance are available but the emergence of virulent pathotypes that are able to overcome one or two resistance alleles can sometimes occur. Both resistance spectra and viral adapta...

Background:
An interesting seed protein family with a role in preventing insect herbivory is the multi-gene, APA family encoding the ?-amylase inhibitor, phytohemagglutinin and arcelin proteins of common bean (Phaseolus vulgaris). Variability for this gene family exists and has been exploited to ...
