Analyses of Twelve New Whole Genome Sequences of Cassava Brown Streak Viruses and Ugandan Cassava Brown Streak Viruses from East Africa: Diversity, Supercomputing and Evidence for Further Speciation. [PDF]

PLoS ONE, 2015
Cassava brown streak disease is caused by two devastating viruses, Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV) which are frequently found infecting cassava, one of sub-Saharan Africa's most important staple food crops.

High-Throughput Virus Screening in Crosses of South American and African Cassava Germplasm Reveals Broad-Spectrum Resistance against Viruses Causing Cassava Brown Streak Disease and Cassava Mosaic Virus Disease

Agronomy, 2022
Screening cassava lines for resistance against viruses causing cassava brown streak disease (CBSD) is cumbersome because of the unpredictable and erratic virus infections in the slow plant infection processes that are frequently not associated with ...

A dataset of necrotized cassava root cross-section images

Data in Brief, 2020
Cassava brown streak disease is a major disease affecting cassava. Along with foliar chlorosis and stem lesions, a very common symptom of cassava brown streak disease is the development of a dry, brown corky rot within the starch bearing tuberous roots ...

Farmer and Field Survey in Cassava-Growing Districts of Rwanda Reveals Key Factors Associated With Cassava Brown Streak Disease Incidence and Cassava Productivity

Frontiers in Sustainable Food Systems, 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

Occurrence of cassava brown streak disease and associated #Ugandan cassava brown streak virus# in Mayotte Island (Mozambique Channel). [SP4-10] [PDF]

, 2016
International audienceIn November 2013, symptoms of yellowing on leaves and brown necrotic rot on tuberous roots were observed on different cassava landraces (Manihot esculenta) in Dembeni on Mayotte Island, a French Overseas Department in the south-west

Exploiting the combination of natural and genetically engineered resistance to cassava mosaic and cassava brown streak viruses impacting cassava production in Africa. [PDF]

PLoS ONE, 2012
Cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) are currently two major viral diseases that severely reduce cassava production in large areas of Sub-Saharan Africa. Natural resistance has so far only been reported for CMD in cassava.

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

New Disease Reports, 2011
Cassava brown streak disease (CBSD) is a virus disease of great economic importance in East and Central Africa. The earliest reports recognised CBSD as a virus disease spread both through infected cuttings and by a whitefly vector (Storey,…

Survey of cassava brown streak disease and association of factors influencing its epidemics in smallholder cassava cropping systems of coastal Kenya

Frontiers in Sustainable Food Systems, 2023
Cassava productivity is threatened by viral diseases which have become the main phytosanitary problems in cassava farmers. Cassava brown streak disease (CBSD) is a devastating viral disease caused by Cassava brown streak virus (CBSV) and Ugandan cassava ...

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
