Molecular evidence for the association of a strain of Uganda variant of East African cassava mosaic virus to symptom severity in cassava (Manihot esculenta Crantz) fields in Togo [PDF]

, 2009
: Problem statement: This study was carried out to demonstrate that the severity of Cassava Mosaic Disease (CMD) in Togo, is not only influenced by synergism between cassava Begomoviruses in presence, but essentially by recombination between the ...

CRISPR/Cas‐Mediated Gene Editing in Plant Immunity and Its Potential for the Future Development of Fungal, Oomycete, and Bacterial Pathogen‐Resistant Pulse Crops

Plant, Cell &Environment, EarlyView.
ABSTRACT Pulses provide myriad health benefits and are advantageous in an environmental context as a result of their leguminous nature. However, phytopathogenic fungi, oomycetes and bacteria pose a substantial threat to pulse production, at times leading to crop failure.

A discrete-time mathematical model for mosaic disease dynamics in cassava: Neimark-Sacker bifurcation and sensitivity analysis

AIMS Mathematics
Cassava mosaic disease remains a significant threat to cassava production, leading to severe yield losses and food insecurity. While several continuous-time models have been proposed to understand cassava mosaic disease transmission, there is limited ...

Dose-dependent RNAi-mediated geminivirus resistance in the tropical root crop cassava [PDF]

, 2018
Cassava mosaic disease is a major constraint for cassava production in Africa, resulting in significant economic losses. We have engineered transgenic cassava with resistance to African cassava mosaic virus (ACMV), by expressing ACMV AC1-homologous ...

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

Advanced Science, Volume 13, Issue 7, 3 February 2026.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.

Targeting dCas9‐SunTag to a Susceptibility Gene Promoter Is Sufficient for CRISPR Interference

Plant Direct, Volume 10, Issue 2, February 2026.
ABSTRACT Cassava production in sub‐Saharan Africa is severely impacted by diseases. Most pathogens require interaction with host susceptibility factors to complete their life cycles and cause disease. Targeted DNA methylation is an epigenetic strategy to alter gene expression in plants, and we previously reported that a zinc‐finger fused to DMS3 could ...

Genotype × environment interaction effects on early fresh storage root yield and related traits in cassava

Crop Journal, 2014
Cassava (Manihot esculenta Crantz) is an important root crop worldwide. It exhibits substantial differential genotypic responses to varying environmental conditions, a phenomenon termed genotype × environment interaction (GEI). A significant GEI presents

Realized Genetic Gain in Spittlebugs (Hemiptera: Cercopidae) Resistance and Tolerance at CIAT's Interspecific Urochloa Breeding Programme

Plant Breeding, Volume 145, Issue 1, Page 132-141, February 2026.
ABSTRACT The Interspecific Urochloa recurrent selection breeding programme at CIAT aims to integrate desirable traits such as resistance and tolerance to spittlebugs (Hemiptera: Cercopidae), the main insect pest affecting these pastures in Latin America.

Optimal control applied to a stage-structured cassava mosaic disease model with vector feeding behavior

Results in Control and Optimization
Cassava remains Sub-Saharan Africa’s second most crucial staple food crop after maize. However, production of sufficient yields is hampered by pests and diseases. In particular, the whitefly (Bemisia tabaci) has the potential to reduce expected yields by

Surveillance for Sri Lankan cassava mosaic virus (SLCMV) in Cambodia and Vietnam one year after its initial detection in a single plantation in 2015.

PLoS ONE, 2019
Cassava mosaic disease, one of the ten most economically important crop viral diseases in the world, was first reported in Southeast Asia from a single plantation in Cambodia in 2015.
