Unusual occurrence of a DAG motif in the Ipomovirus Cassava brown streak virus and implications for its vector transmission. [PDF]

PLoS ONE, 2017
Cassava is the main staple food for over 800 million people globally. Its production in eastern Africa is being constrained by two devastating Ipomoviruses that cause cassava brown streak disease (CBSD); Cassava brown streak virus (CBSV) and Ugandan ...

Efficient transmission of cassava brown streak disease viral pathogens by chip bud grafting. [PDF]

BMC Res Notes, 2013
Abstract Background Techniques to study plant viral diseases under controlled growth conditions are required to fully understand their biology and investigate host resistance. Cassava brown streak disease (CBSD) presents a major threat to cassava production in East Africa.

Disparity between leaf and root symptoms and crop losses associated with cassava brown streak disease in four countries in eastern Africa [PDF]

, 2016
Cassava brown streak disease is endemic to the coastal regions of East Africa, and from around 2004, the disease resurged and became epidemic in the Great Lakes Region, where it continues to spread. In both these areas, cassava brown streak disease (CBSD)

Analysis of cassava brown streak viruses reveals the presence of distinct virus species causing cassava brown streak disease in East Africa

Journal of General Virology, 2010
Cassava brown streak virus (CBSV) isolates were analysed from symptomatic cassava collected between 1997 and 2008 in the major cultivation regions of East Africa. An analysis of complete RNA genomes of seven isolates from Kenya, Tanzania, Mozambique, Uganda and Malawi revealed a common genome structure, but the isolates clearly clustered in two ...

Characterization of Brown Streak Virus–Resistant Cassava

Molecular Plant-Microbe Interactions, 2016
Cassava brown streak disease (CBSD) has become a major constraint to cassava production in East and Central Africa. The identification of new sources of CBSD resistance is essential to deploy CBSD mitigation strategies, as the disease is progressing ...

Pro‐Vitamin A Biofortified Cavendish Banana: Trait Stability in the Field

Plant Biotechnology Journal, EarlyView.
ABSTRACT Vitamin A deficiency (VAD), a major global health concern, has driven efforts to develop staple crops with enhanced pro‐vitamin A (pVA) content. Delivering meaningful nutritional benefits, however, requires technologies that maintain elevated carotenoid levels under field conditions. Previous proof‐of‐concept work demonstrated that pVA content

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

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 ...
