Survey of cassava brown streak disease and association of factors influencing its epidemics in smallholder cassava cropping systems of coastal Kenya

Frontiers in Sustainable Food Systems, 2023
Cassava productivity is threatened by viral diseases which have become the main phytosanitary problems in cassava farmers. Cassava brown streak disease (CBSD) is a devastating viral disease caused by Cassava brown streak virus (CBSV) and Ugandan cassava ...

Genetic Diversity and Distribution of Cassava Brown Streak Virus and Ugandan Cassava Brown Streak Virus in Major Cassava-growing Regions in Kenya

Annual Research & Review in Biology, 2016
Cassava brown streak disease (CBSD) is caused by two viruses; Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV) that are genetically distinct. The disease can cause losses of up to 100 million US Dollars and it has a big impact on cassava yields.

A dataset of cassava whitefly count images

Data in Brief, 2022
Whiteflies are insect vectors that affect a variety of plants such as tomatoes, cabbages, sweet potatoes, eggplants, and cassava. In Uganda, whiteflies are a major contributor to the spread of Cassava Brown Streak Disease (CBSD).

Characterising Genetic Diversity in Cassava Brown Streak Virus [PDF]

, 2018
Abstract Plant viruses represent a significant threat to food security for many global populations. Cassava Brown Streak Virus (CBSV) causes immense damage to cassava crops in Eastern, Central and Southern Africa. The eradication of CBSV is a difficult challenge, as it has been shown to be fast-evolving and it is transmitted by flying ...

Virulence and Molecular Detection of Cassava Mosaic and Brown Streak Virus Genes on Elite Mutant Cassava Lines

Biotechnology Journal International, 2023
Unavailability of germplasm with Cassava Brown Streak Disease (CBSD) and Cassava Mosaic Disease (CMD) tolerance genes remains the main bottleneck towards management of the two diseases in tropic and sub-tropic regions in Africa. We assessed the pathogenicity of two viruses and established the presence of genes linked to CBSD and CMD among some elite ...

Incidence, severity and distribution of Cassava brown streak disease in northeastern Democratic Republic of Congo

Cogent Food & Agriculture, 2020
Cassava fields were prospected from two provinces of the Democratic Republic of Congo (Ituri and Haut Uélé) to evaluate the ampleness of Cassava brown streak disease (CBSD) infection.

Candidate genes for field resistance to cassava brown streak disease revealed through the analysis of multiple data sources

Frontiers in Plant Science, 2023
Cassava (Manihot esculenta Crantz) is a food and industrial storage root crop with substantial potential to contribute to managing risk associated with climate change due to its inherent resilience and in providing a biodegradable option in manufacturing.

First Report of Mixed Infection of Cassava Brown Streak Virus and Ugandan Cassava Brown Streak Virus on Cassava in North-eastern Democratic Republic of Congo

Plant Disease, 2019
Cassava brown streak disease (CBSD), caused by two viruses (Cassava brown streak virus and Ugandan cassava brown streak virus) is one of the most important diseases affecting cassava in East and Central Africa. The viruses are spread through infected stem cuttings and by the whitefly Bemisia tabaci.

First report of Ugandan cassava brown streak virus on cassava in Democratic Republic of Congo [PDF]

New Disease Reports, 2012
Ugandan cassava brown streak virus (UCBSV) and Cassava brown streak virus (CBSV) (Potyviridae: Ipomovirus) are causal agents of cassava brown streak disease (CBSD), a disease of cassava that presents a significant threat to the food…

Genetic diversity and SNP’s from the chloroplast coding regions of virus-infected cassava [PDF]

PeerJ, 2020
Cassava is a staple food crop in sub-Saharan Africa; it is a rich source of carbohydrates and proteins which currently supports livelihoods of more than 800 million people worldwide. However, its continued production is at stake due to vector-transmitted
