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 ...

Field evaluation of selected cassava genotypes for cassava brown streak disease based on symptom expression and virus load [PDF]

, 2016
Background Production of cassava (Manihot esculenta Crantz), a food security crop in sub-Saharan Africa, is threatened by the spread of cassava brown streak disease (CBSD) which manifests in part as a corky necrosis in the storage root.

Improved cross entropy loss for noisy labels in vision leaf disease classification

IET Image Processing, Volume 16, Issue 6, Page 1511-1519, May 2022., 2022
Abstract The predictive performance of supervised learning algorithms depends on the quality of labels. In a typical label collection process, multiple annotators provide subjective noisy estimates of the “truth” under the influence of their varying skill‐levels and biases.

The role of the whitefly, Bemisia tabaci (Gennadius), and farmer practices in the spread of cassava brown streak ipomoviruses [PDF]

, 2017
Cassava brown streak disease (CBSD) is arguably the most dangerous current threat to cassava, which is Africa's most important food security crop. CBSD is caused by two RNA viruses: Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus

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).

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 ...

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.

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.
