Relationship between Symptoms Expression and Virus Detection in Cassava Brown Virus Streak-Infected Plants

Journal of Agricultural Science, 2012
Diagnosis of Cassava brown streak disease (CBSD) has for long been based on foliar and root symptoms expression on infected plants. Variability in patterns of symptoms expression between varieties and seasons however, has meant that symptom-based diagnostics are unreliable.

Elimination of Cassava Brown Streak Virus from Infected Cassava

, 2014
Cassava brown streak disease (CBSD) is an economically important disease of cassava (Manihot esculenta crantz) caused by Cassava brown streak virus (CBSV). Use of clean planting material is one of the strategies for disease management. However, obtaining

RNAi-mediated resistance to diverse isolates belonging to two virus species involved in Cassava brown streak disease

, 2010
Cassava brown streak disease (CBSD) is emerging as one of the most important viral diseases of cassava (Manihot esculenta) and is considered today as the biggest threat to cassava cultivation in East Africa.

Gradual Emergence of East African cassava mosaic Cameroon virus in Cassava Farms in Côte d’Ivoire

Agronomy
Cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) are endemic threats to cassava production, causing significant yield losses. They are caused respectively by begomoviruses and ipomoviruses that are transmitted by whiteflies and ...

Assessing the effect of sample storage time on viral detection using a rapid and cost-effective CTAB-based extraction method

Plant Methods
Background Cassava leaf samples degrade quickly during storage and transportation from distant areas. Proper sampling and efficient, low-cost storage methods are critical for obtaining sufficient quality DNA and RNA for plant virus epidemiology and ...

Identification of immune response genes of cassava during early phases of cassava brown streak virus infection

Crop Breeding, Genetics and Genomics
Abstract Cassava brown streak disease (CBSD) caused by the ipomoviruses CBSV and UCBSV, poses a significant threat to cassava crops and the destruction of tuberous roots leads to substantial yield losses. Virus resistance identified in some South American cassava germplasm lines inhibits virus replication and movement and, is a complete

High-Throughput Field Screening of Cassava Brown Streak Disease Resistance for Efficient and Cost-Saving Breeding Selection

Agronomy
Cassava brown streak disease (CBSD) remains the most severe threat to cassava production in the Great Lakes region and Southern Africa. Screening for virus resistance by subjecting cassava to high virus pressure in the epidemic zone (hotspots) is a ...
