Epidemiological modelling and host distribution mapping to inform pathogen surveillance: the cassava brown streak disease (CBSD) pandemic in sub-Saharan Africa

, 2019
We illustrate the process undertaken to inform surveillance for cassava brown streak disease (CBSD). CBSD is currently the most devastating cassava pathogen in East, central and southern Africa affecting a staple crop for over 700 million people on the continent and posing a major threat to West Africa. The process involved the following steps: firstly

Progress and Impacts of “Omics” Technologies in Understanding the Drought Response in Cassava: Adoption for Food Security in Africa

Plant-Environment Interactions, Volume 6, Issue 6, December 2025.
ABSTRACT Cassava is a crucial staple crop in Africa, but its productivity is increasingly threatened by the worsening impacts of drought caused by climate change. To address this challenge, an integration of “omics” and genome editing technologies has emerged as indispensable tools for understanding the complex mechanisms that govern cassava's response

Table_4_Farmer and Field Survey in Cassava-Growing Districts of Rwanda Reveals Key Factors Associated With Cassava Brown Streak Disease Incidence and Cassava Productivity.docx

, 2021
Cassava (Manihot esculenta Crantz) is a vital crop in Rwanda where it ranks as the third most consumed staple. However, cassava productivity remains below its yield potential due to several constraints, including important viral diseases, such as cassava

Global Cassava Germplasm Resources: Industrial and Technological Development

Food and Energy Security, Volume 14, Issue 5, September/October 2025.
ABSTRACT The main cassava‐producing regions include Africa, South America, Southeast Asia, and China. Due to significant differences in natural environments, industrial backgrounds, and technological resources for germplasm development across these regions, the utilization of cassava germplasm resources shows regional variation.

Progression of Cassava Brown Streak Disease (CBSD) in infected cassava roots in Uganda

Uganda Journal of Agricultural Sciences, 2015
Cassava Brown Streak disease (CBSD) has and continues to be a major threat to the cassava industry in Uganda. The most economically damaging symptom of CBSD occurs on the roots as a yellow/brown, corky necrosis. However, the onset and development of this necrosis is not known.

Evaluating Consumer Perceptions and Safety of Genetically Modified Foods in Africa: A Comprehensive Review

Food Science &Nutrition, Volume 13, Issue 6, June 2025.
The manuscript highlights the potential of GMF to address food insecurity in Africa by improving crop yields, enhancing nutritional value, and reducing reliance on agrochemicals. However, there are public concerns about safety, environmental risks, and ethical implications, coupled with misinformation and inadequate regulatory frameworks that hinder ...

Re-emergence of Cassava Brown Streak Disease in Uganda

, 2007
During November 2004, veinal chlorosis on mature cassava leaves, typical of cassava brown streak disease (CBSD), was observed at Mukono in central Uganda. Five out of 11 cultivars at the site showed CBSD symptoms (incidence range 4 to 64%).

The Transcriptome Response of African and South American Cassava (Manihot esculenta) to Infection by East African Cassava Mosaic Virus‐Uganda

Plant Pathology, Volume 74, Issue 4, Page 1068-1077, May 2025.
The early defence response in cassava plants is associated with EACMV‐Ug resistance, while the susceptible varieties' response is delayed and expresses fewer unique differentially expressed genes. ABSTRACT Cassava mosaic begomoviruses (CMBs) cause the economically important cassava mosaic disease (CMD) in cassava.
