Optimisation of in vitro techniques for cassava brown streak virus elimination from infected cassava clones

African Crop Science Journal, 2011
Cassava brown streak disease (CBSD), caused by Cassava brown streak virus (CBSV), is an economically important disease of cassava (Manihot esculenta Crantz) in East Africa. The objective of this study was tooptimise in vitro techniques for CBSV elimination from infected Ugandan cassava cultivars.

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.

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.

Detection of cassava brown streak ipomoviruses in aphids collected from cassava plants

Frontiers in Sustainable Food Systems, 2023
Cassava is an important staple food in Africa and a major source of carbohydrates for 800 million people globally. However, cassava suffers severe yield losses caused by many factors including pests and diseases.

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

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,…
