Genome-wide association study of cassava brown streak disease resistance in cassava germplasm conserved in South America [PDF]

Scientific Reports
Cassava (Manihot esculenta Crantz) is a vital carbohydrate source for over 800 million people globally, yet its production in East Africa is severely affected by cassava brown streak disease (CBSD). Genebanks, through ex-situ conservation, play a pivotal

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

Virol J, 2014
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.

Genetic complexity of cassava brown streak disease: insights from qPCR-based viral titer analysis and genome-wide association studies [PDF]

Frontiers in Plant Science
Cassava, a vital global food source, faces a threat from Cassava Brown Streak Disease (CBSD). CBSD results from two viruses: Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV). These viruses frequently pose challenges to the

Cassava brown streak virus disease: Past, present and future. [PDF]

, 2002
Cassava has been an important success story in Africa's developing agriculture over the past decade. The crop's inherei'lt capacity to cope with marginal growing conditions and unpredictable rainfall, coupled with determined efforts of a number of ...

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

Unlocking Cassava Brown Streak Disease Resistance in Cassava: Insights from Genetic Variability and Combining Ability

Agronomy
Cassava brown streak disease (CBSD) threatens cassava production in sub-Saharan Africa despite the availability of resistant varieties. Extreme environmental factors weaken plant defenses, reducing CBSD resistance. This study examined CBSD inheritance in

Genetic dissection of cassava brown streak disease in a genomic selection population. [PDF]

Front Plant Sci, 2022
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 ...

Artificial microRNA-derived resistance to Cassava brown streak disease. [PDF]

J Virol Methods, 2016
Artificial miRNAs (amiRNA) were generated targeting conserved sequences within the genomes of the two causal agents of Cassava brown streak disease (CBSD): Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV). Transient expression studies on ten amiRNAs targeting 21nt conserved sequences of P1(CBSV and UCBSV), P3(CBSV and ...
