Cassava Brown Streak Disease Response and Association With Agronomic Traits in Elite Nigerian Cassava Cultivars [PDF]

Frontiers in Plant Science, 2021
Cassava mosaic geminiviruses (CMGs) and cassava brown streak viruses (CBSVs) cause the highest yield losses in cassava production in Africa. In particular, cassava brown streak disease (CBSD) is and continues to be a significant constraint to optimal ...

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

Journal of Virological 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 ...

Community phytosanitation to manage cassava brown streak disease [PDF]

Virus Research, 2017
Cassava viruses are the major biotic constraint to cassava production in Africa. Community-wide action to manage them has not been attempted since a successful cassava mosaic disease control programme in the 1930s/40s in Uganda. A pilot initiative to investigate the effectiveness of community phytosanitation for managing cassava brown streak disease ...

Resistance Against Cassava Brown Streak Viruses From Africa in Cassava Germplasm From South America [PDF]

Frontiers in Plant Science, 2019
Cassava brown streak disease (CBSD) is a severe virus disease of cassava and prevalent in the eastern regions of Africa. The disease is characterized by distinct vein chlorosis and streak symptoms on leaves and stems and necrosis of storage roots.

Metagenomics Analysis of Viruses Associated with Cassava Brown Streak Disease in Kenya [PDF]

Viruses
Cassava brown streak disease (CBSD), caused by cassava brown streak virus (CBSV; Ipomovirus brunusmanihotis) and Ugandan cassava brown streak virus (UCBSV; Ipomovirus manihotis) (family Potyviridae, genus Ipomovirus), is increasingly becoming a threat to

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

Crop Protection, 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

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

Transcriptional response of virus-infected cassava and identification of putative sources of resistance for cassava brown streak disease. [PDF]

PLoS ONE, 2014
Cassava (Manihot esculenta) is a major food staple in sub-Saharan Africa, which is severely affected by cassava brown streak disease (CBSD). The aim of this study was to identify resistance for CBSD as well as to understand the mechanism of putative ...

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
