Cassava brown streak disease and the sustainability of a clean seed system [PDF]
One method of reducing disease in crops is the dissemination of disease‐free planting material from a multiplication site to growers. This study assesses the validity and sustainability of this method for cassava brown streak disease, a threat to cassava crops across East Africa.

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

Training Population Optimization for Prediction of Cassava Brown Streak Disease Resistance in West African Clones [PDF]
Cassava production in the central, southern and eastern parts of Africa is under threat by cassava brown streak virus (CBSV). Yield losses of up to 100% occur in cases of severe infections of edible roots.

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

Cassava Brown Streak Disease and Ugandan cassava brown streak virus Reported for the First Time in Zambia [PDF]
A diagnostic survey was conducted in July 2017 in two northern districts of Zambia to investigate presence or absence of cassava brown streak disease (CBSD) and its causal viruses. In total, 29 cassava fields were surveyed and cassava leaf samples were collected from 116 plants (92 symptomatic and 24 nonsymptomatic).

Cassava brown streak disease: a threat to food security in Africa [PDF]
Cassava brown streak disease (CBSD) has emerged as the most important viral disease of cassava (Manihot esculenta) in Africa and is a major threat to food security. CBSD is caused by two distinct species of ipomoviruses, Cassava brown streak virus and Ugandan cassava brown streak virus, belonging to the family Potyviridae. Previously, CBSD was reported

Genetic dissection of cassava brown streak disease in a genomic selection population [PDF]
IntroductionCassava brown streak disease (CBSD) is a major threat to food security in East and central Africa. Breeding for resistance against CBSD is the most economical and sustainable way of addressing this challenge. MethodsThis study seeks to assess the (1) performance of CBSD incidence and severity; (2) identify genomic regions associated with ...

PAL1 gene of the phenylpropanoid pathway increases resistance to the Cassava brown streak virus in cassava [PDF]
Background The phenylalanine ammonia lyase genes play crucial role in plant response to biotic and abiotic stresses. In this study, we characterized the role of PAL genes in increasing resistance to the Cassava brown streak virus that causes the ...
