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.

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 ...

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.

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.

Surveillance and distribution of the emergent Sri Lankan cassava mosaic virus in China

Phytopathology Research, 2020
Cassava (Manihot esculenta Crantz) is a major staple food crop for more than a billion people in the world. Cassava mosaic virus (CMV), belonging to the Geminiviridae family, is a primary threat to cassava production.

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

African Cassava Mosaic Disease

, 2008
Cassava mosaic disease (CMD), recognized in Africa for more than a century, is now known to be caused by a group of geminiviruses in the genus Begomovirus from the family Geminiviridae. All are transmitted in a persistent manner by the whitefly vector, Bemisia tabaci.

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

Population Ecology, Volume 68, Issue 1, January 2026.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...
