Expansion and impact of cassava brown streak and cassava mosaic diseases in Africa: A review

Frontiers in Sustainable Food Systems, 2022
Africa produces over half of global cassava; however, the continent's average yield is below the potential yields achieved under experimental conditions. Many factors contributing to low yield include lack of quality varieties, poor soils, limited access

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 ...

Early detection of plant virus infection using multispectral imaging and spatial–spectral machine learning

Scientific Reports, 2022
Cassava brown streak disease (CBSD) is an emerging viral disease that can greatly reduce cassava productivity, while causing only mild aerial symptoms that develop late in infection. Early detection of CBSD enables better crop management and intervention.

Host and virus effects on reversion in cassava affected by cassava brown streak disease [PDF]

, 2016
The phenomenon of virus-infected plants naturally recovering health is known as ‘reversion’, and is a type of resistance mechanism exploited in some crop plants for disease control.

Table_3_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

Cassava molecular genetics and genomics for enhanced resistance to diseases and pests. [PDF]

Mol Plant Pathol
Combating cassava diseases and pests requires a holistic approach that combines traditional breeding methods, genomics and biotechnology innovations such as conventional genetic engineering and genome editing. Abstract Cassava (Manihot esculenta) is one of the most important sources of dietary calories in the tropics, playing a central role in food and

Risk factors associated with cassava brown streak disease dissemination through seed pathways in Eastern D.R. Congo

Frontiers in Plant Science, 2022
Vegetatively propagated crops are particularly prone to disease dissemination through their seed systems. Strict phytosanitary measures are important to limit the impact of diseases as illustrated by the potato seed system in Europe. Cassava brown streak

Production of virus-free cassava through hot water therapy and two rounds of meristem tip culture

Cogent Food & Agriculture, 2020
Cassava genetic resources are highly threatened by devastating viral diseases. It is therefore important to conserve the specifically farmer-preferred landraces/cultivars that are highly susceptible. The study assessed the efficiency of hot water therapy
