Cassava brown streak disease in Rwanda, the associated viruses and disease phenotypes. [PDF]

Plant Pathol, 2018
Cassava brown streak disease (CBSD) was first observed on cassava ( Manihot esculenta ) in Rwanda in 2009. In 2014 eight major cassava‐growing districts in the country were surveyed to determine the distribution and variability of symptom phenotypes associated with CBSD, and the genetic ...

Cassava brown streak disease: historical timeline, current knowledge and future prospects. [PDF]

Mol Plant Pathol, 2018
Summary Cassava is the second most important staple food crop in terms of per capita calories consumed in Africa and holds potential for climate change adaptation. Unfortunately, productivity in East and Central Africa is severely constrained by two viral diseases: cassava mosaic disease (CMD) and cassava brown streak disease (CBSD ...

Comparative compositional analysis of cassava brown streak disease resistant 4046 cassava and its non-transgenic parental cultivar. [PDF]

GM Crops Food, 2021
Compositional analysis is an important component of an integrated comparative approach to assessing the food and feed safety of new crops developed using biotechnology. As part of the safety assessment of cassava brown streak disease resistant 4046 cassava, a comprehensive assessment of proximates, minerals, amino acids, fatty acids, vitamins, anti ...

Strategies for the Construction of Cassava Brown Streak Disease Viral Infectious Clones. [PDF]

Mol Biotechnol, 2019
Cassava brown streak disease (CBSD) has major impacts on yield and quality of the tuberous roots of cassava in Eastern and Central Arica. At least two Potyviridae species cause the disease: Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV). Cloned viral genome sequences known as infectious clones (ICs) have been important

Epidemiological Analysis of Cassava Mosaic and Brown Streak Diseases, and Bemisia tabaci in the Comoros Islands

Viruses, 2022
A comprehensive assessment of cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) was carried out in Comoros where cassava yield (5.7 t/ha) is significantly below the African average (8.6 t/ha) largely due to virus diseases. Observations

First report of cassava brown streak disease and associated Ugandan cassava brown streak virus in Mayotte Island [PDF]

New Disease Reports, 2014
In November 2013, symptoms of yellowing on leaves and brown necrotic rot on tuberous roots (Fig. 1) were observed on different cassava landraces (Manihot esculenta) in Dembeni on Mayotte Island, a French Overseas Department in the southwest Indian Ocean.

Eleven years of breeding efforts to combat cassava brown streak disease. [PDF]

Breed Sci, 2016
Cassava (Manihot esculenta Crantz) production is currently under threat from cassava brown streak disease (CBSD), a disease that is among the seven most serious obstacles to world's food security. Three issues are of significance for CBSD. Firstly, the virus associated with CBSD, has co-evolved with cassava outside its center of origin for at least 90 ...

Plot based heritability estimates and categorization of cassava genotype response to cassava brown streak disease. [PDF]

Crop Prot, 2018
Cassava brown streak disease (CBSD) caused by Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV) is a threat to food security in sub-Saharan Africa, where the disease persistently reduces overall root quality and quantity resulting in up to 100% yield losses. Complexities in CBSD symptom expression and the damage caused on
