Biotechnological approaches to determine the impact of viruses in the energy crop plant Jatropha curcas

open access: yesVirology Journal, 2011
Background Geminiviruses infect a wide range of plant species including Jatropha and cassava both belonging to family Euphorbiaceae. Cassava is traditionally an important food crop in Sub - Saharan countries, while Jatropha is considered as valuable ...

Attempts to Identify Cassava Brown Streak Virus in Western Democratic Republic of Congo

open access: yesJournal of Agricultural Science, 2019
Root necrosis similar to those of the cassava brown streak disease (CBSD) were observed on cassava in western provinces of the Democratic Republic of Congo (DR.Congo) in the early 2000’s. However molecular laboratory diagnosis were not able to detect any causative agent responsible for the attacks, hence, the disease related to these symptoms

Cassava disease detection using a lightweight modified soft attention network

open access: yesPest Management Science, Volume 81, Issue 2, Page 607-617, February 2025.
The main framework of the proposed CDDNet approach. Abstract BACKGROUND Cassava is a high‐carbohydrate crop that is at risk of viral infections. The production rate and quality of cassava crops are affected by several diseases. However, the manual identification of diseases is challenging and requires considerable time because of the lack of field ...

Reprogrammed Plant Metabolism During Viral Infections: Mechanisms, Pathways and Implications

open access: yesMolecular Plant Pathology, Volume 26, Issue 2, February 2025.
This review highlights how plant viruses reprogramme host metabolism, elucidates underlying mechanisms and discusses advanced antiviral strategies, including gene‐editing and metabolomics‐guided approaches. ABSTRACT Plant viruses pose a significant threat to global agriculture, leading to substantial crop losses that jeopardise food security and ...

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

open access: yes, 2016
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.

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

open access: yes, 2023
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.

Alternative Approaches for Assessing Cassava Brown Streak Root Necrosis to Guide Resistance Breeding and Selection

open access: yesFrontiers in Plant Science, 2019
Cassava brown streak disease (CBSD) caused by the rapidly evolving cassava brown streak viruses (CBSVs), causes immense yield losses to the cassava value chain in eastern and southern Africa. Western Africa, another region that heavily depends on cassava
