Progress and Impacts of "Omics" Technologies in Understanding the Drought Response in Cassava: Adoption for Food Security in Africa. [PDF]

Plant Environ Interact
ABSTRACT Cassava is a crucial staple crop in Africa, but its productivity is increasingly threatened by the worsening impacts of drought caused by climate change. To address this challenge, an integration of “omics” and genome editing technologies has emerged as indispensable tools for understanding the complex mechanisms that govern cassava's response

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.

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

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 ...

High-Throughput Virus Screening in Crosses of South American and African Cassava Germplasm Reveals Broad-Spectrum Resistance against Viruses Causing Cassava Brown Streak Disease and Cassava Mosaic Virus Disease

Agronomy, 2022
Screening cassava lines for resistance against viruses causing cassava brown streak disease (CBSD) is cumbersome because of the unpredictable and erratic virus infections in the slow plant infection processes that are frequently not associated with ...

Nymphstar: An accurate high‐throughput quantitative method for whitefly (Aleurotrachelus socialis Bondar) resistance phenotyping in cassava

The Plant Phenome Journal, Volume 6, Issue 1, December 2023., 2023
Abstract Whitefly (Aleurotrachelus socialis Bondar) is a major pest causing significant economic losses in cassava production systems in North South America. It diminishes cassava's photosynthesis by colonizing leaves, directly feeding on phloem sap, or excreting substances that foster sooty mold growth, reducing the photosynthetic area.
