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.

Farmers' Knowledge of Cassava Streak Virus Disease in Selected Districts of Central Uganda [PDF]

, 2017
Cassava brown streak disease is one of the latest outbreaks of diseases threatening cassava production in Uganda. Although, previously reported in some parts of east African coast, CBSD was not a common problem in Uganda until over a decade ago.

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.

Editing of the MeSWEET10a promoter yields bacterial blight resistance in cassava cultivar SC8

Molecular Plant Pathology, Volume 25, Issue 10, October 2024.
Cassava cultivar South China No. 8 plants with an edited EBETALE20 region of the MeSWEET10a promoter displayed increased resistance to Xanthomonas axonopodis pv. manihotis strain Xam11 without yield penalty. Abstract Cassava starch is a widely used raw material for industrial production and food source for people. However, cassava bacterial blight (CBB)

Cassava whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), in sub-Saharan African farming landscapes: a review of the factors determining abundance [PDF]

, 2018
Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a pest species complex that causes widespread damage to cassava, a staple food crop for millions of smallholder households in Sub-Saharan Africa. Species in the complex cause direct feeding damage to

Cyanide in cassava: Understanding the drivers, impacts of climate variability, and strategies for food security

Food and Energy Security, Volume 13, Issue 4, July/August 2024.
Abstract The consumption of cassava, a vital staple food for more than 1 billion people worldwide, holds particular significance in sub‐Saharan Africa (SSA). Expansion in cassava production in SSA is driven by increasing market demand, local consumption, and adaptability to diverse environments.

Adoption determinants of improved cassava varieties and intercropping among East and Central African smallholder farmers

Journal of the Agricultural and Applied Economics Association, Volume 3, Issue 2, Page 292-310, June 2024.
Abstract A key constraint to cassava productivity in Africa is the lack of adoption of improved cassava varieties tolerant to pests and diseases. To understand the drivers of adoption behavior, we examine the simultaneous adoption of improved cassava varieties and intercropping by 1200 smallholder farmers in Malawi, Tanzania, and Uganda. Using a linear

Beyond the present: How climate change is relevant to pest risk analysis

EPPO Bulletin, Volume 54, Issue S1, Page 20-37, March 2024.
Abstract Climate change is widely recognized as a critical global challenge with far‐reaching consequences. It affects pest species by altering their population dynamics, actual and potential distribution areas, as well as interactions with their hosts and natural enemies. Climate change thus has potentially important implications for multiple areas of
