According to studies in human and mouse species it is apparent that both CD40 ligand and tumor necrosis factor alpha (TNF alpha) are members of a novel family of cytokines, referred to as the TNF - superfamily. This article reports the cloning of the cattle CD40 lignad and cattle TNF alpha, and s...

El añublo del arroz causado por Pyricularia grisea (Sacc) es la principal enfermedad del cultivo en todo el mundo. El desarrollo dc variedades resistentes es el método preferido para el control de la enfermedad; sin embargo, las variedades pierden su resistencia en períodos de 1 a 2 años después ...

Cassava is the staple food in the Democratic Republic of Congo (DRC) where both the roots and leaves are consumed. This crop is susceptible to several viral diseases, including Cassava Mosaic Disease(CMD) and Cassava Brown Streak Disease(CBSD) in eastern DRC. Following earlier studies that show r...

Bean common mosaic virus (BCMV) is seed transmitted and the most important virus disease of beans in Africa. A breeding programme was initiated in 1990 in Uganda to develop lines with resistance to necrotic strains that predominate in the continent. Evaluation of field layout on infection level s...

Cassava brown streak disease (CBSD) is an economically important virus disease causing significant losses to cassava root yield and quality in east, central and southern Africa. Breeding for resistance in cassava requires an understanding of the underlying genetic control of CBSD resistance. Sour...

Studies were undertaken to determine disease interactions involving P. goodeyi and a non-pathogenic strain of F. oxysporum, both responsible for root-rotting and subsequent toppling of 2 banana cultivars in Kenya. Thirty days after inoculation of young banana plants with P. goodeyi alone or in co...

High necrosis and poor survival rate of target plant tissues are some of the major factors that affect the efficiency of Agrobacterium-mediated T-DNA transfer into plant cells. These factors may be the result of, or linked to, hypersensitive defense reaction in plants to Agrobacterium infection, ...
