Eleven years of breeding efforts to combat cassava brown streak disease [PDF]

Breeding Science, 2016
Cassava (Manihot esculenta Crantz) production is currently under threat from cassava brown streak disease (CBSD), a disease that is among the seven most serious obstacles to world's food security. Three issues are of significance for CBSD. Firstly, the virus associated with CBSD, has co-evolved with cassava outside its center of origin for at least 90 ...

Targeting dCas9‐SunTag to a Susceptibility Gene Promoter Is Sufficient for CRISPR Interference [PDF]

Plant Direct, Volume 10, Issue 2, February 2026.
ABSTRACT Cassava production in sub‐Saharan Africa is severely impacted by diseases. Most pathogens require interaction with host susceptibility factors to complete their life cycles and cause disease. Targeted DNA methylation is an epigenetic strategy to alter gene expression in plants, and we previously reported that a zinc‐finger fused to DMS3 could ...

Cassava brown streak virus disease: Past, present and future. [PDF]

, 2002
Cassava has been an important success story in Africa's developing agriculture over the past decade. The crop's inherei'lt capacity to cope with marginal growing conditions and unpredictable rainfall, coupled with determined efforts of a number of countries to move away from over-reliance on maize, have helped establish it as the continent's number one

Survey of cassava mosaic and brown streak diseases and their vector whiteflies in Malawi

Discover Agriculture
Cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) are the two major threats to cassava production in eastern and southern Africa. There have been several interventions over the years in the fight against the two diseases. Whether these

Occurrence of cassava brown streak disease and associated Cassava brown streak virus and Ugandan cassava brown streak virus in the Comoros Islands [PDF]

New Disease Reports, 2017
Cassava brown streak disease (CBSD) has emerged as the most important viral disease of cassava (Manihot esculenta) in Africa and is a major threat to food security. The expanding CBSD epidemic in East and Central Africa is caused by two…

Differential Tropism in Roots and Shoots of Resistant and Susceptible Cassava (Manihot esculenta Crantz) Infected by Cassava Brown Streak Viruses

Cells, 2021
Cassava brown streak disease (CBSD) is a destructive disease of cassava in Eastern and Central Africa. Because there was no source of resistance in African varieties to provide complete protection against the viruses causing the disease, we searched in ...
