UNSUCCESSFUL CASSAVA BROWN STREAK DISEASE (CBSD)EVALUATION ATTEMPTS IN WESTERN DEMOCRATIC REPUBLIC OF CONGO AND IMPLICATIONS WITH CASSAVA ROOT NECROSIS DISEASE (CRND) ETIOLOGY [PDF]

International Journal of Agriculture, Environment and Bioresearch, 2019
Open Access Article ; Cassava brown streak disease (CBSD) is the second most important virus disease after Cassava mosaic disease (CMD), infecting cassava (ManihotesculetaCrantz) in Africa. The disease is caused by two distinct viruses, Cassava brown streak virus [2, 3] and Ugandan Cassava brown streak virus (family, Potyviridae: genus, Ipomovirus ...

Transcriptional response of virus-infected cassava and identification of putative sources of resistance for cassava brown streak disease. [PDF]

PLoS ONE, 2014
Cassava (Manihot esculenta) is a major food staple in sub-Saharan Africa, which is severely affected by cassava brown streak disease (CBSD). The aim of this study was to identify resistance for CBSD as well as to understand the mechanism of putative ...

PAL1 gene of the phenylpropanoid pathway increases resistance to the Cassava brown streak virus in cassava [PDF]

Virology Journal, 2021
Background The phenylalanine ammonia lyase genes play crucial role in plant response to biotic and abiotic stresses. In this study, we characterized the role of PAL genes in increasing resistance to the Cassava brown streak virus that causes the ...

Epidemiological Analysis of Cassava Mosaic and Brown Streak Diseases, and Bemisia tabaci in the Comoros Islands [PDF]

Viruses, 2022
A comprehensive assessment of cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) was carried out in Comoros where cassava yield (5.7 t/ha) is significantly below the African average (8.6 t/ha) largely due to virus diseases. Observations
