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.

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

Cassava mosaic geminiviruses associated with cassava mosaic disease in Rwanda
, 2018 Cassava mosaic disease (CMD), and cassava mosaic geminiviruses (CMGs), were investigated in a country-wide survey conducted in six cassava-producing prefectures (administrative regions) of Rwanda in 2001. CMD occurred throughout the country at an average

Cassava production systems optimized for double output: Seed‐cuttings and root yields
Agronomy Journal, Volume 118, Issue 3, May/June 2026.Abstract Cassava (Manihot esculenta Crantz) is a strategic crop for food security but continues to face major challenges related to low root yields and the lack of optimized systems for producing high‐quality seed‐cuttings. This study evaluated the effects of different planting densities, varieties, and agrochemical‐based seed‐cutting treatments ...

Biotechnology Reports, 2019 Cassava mosaic disease (CMD), caused by geminiviruses, is a major hurdle to cassava production. Due to the heterozygous nature of cassava, breeding for virus resistance is difficult, but cassava has been shown to be a good candidate for genetic ...

Scientific Reports, 2023 Cassava mosaic disease is caused by a complex of whitefly-transmitted begomoviruses, which often occur in co-infections. These viruses have bipartite genomes consisting of DNA-A and DNA-B that are encapsidated into separate virions.

Symptom severity of cassava mosaic disease in relation to concentration of African cassava mosaic virus in different cassava genotypes [PDF]
Plant Pathology, 2003 The concentration of African cassava mosaic virus (ACMV) was assessed by enzyme‐linked immunosorbent assay in relation to symptom severity among resistant, moderately resistant and susceptible cassava genotypes. Resistant genotype NR 8083 had significantly lower symptom severity scores (

PLDC‐Net: A Domain‐Specific Base Model for Plant Leaf Disease Classification Domain Adaptation Tasks
Plant Direct, Volume 10, Issue 4, April 2026.ABSTRACT Plant diseases are the cause of heavy losses of crop production and, therefore, a big contributor to food shortages. Identifying these diseases as early as possible is important to limit the negative effects that these diseases have on the yields, as slow response time will lead to the spread of diseases and further loss.

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.

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2187-2200, April 2026.ABSTRACT Tomato yellow leaf curl China virus (TYLCCNV) is a major agricultural pathogen and primary model for circular single‐stranded DNA (cssDNA) virus studies. The infectious clones of TYLCCNV and other cssDNA viruses are usually constructed as two tandem copies of the small viral genomes in Agrobacterium‐mediated T‐DNA vectors.
