Maf/ham1-like pyrophosphatases of non-canonical nucleotides are host-specific partners of viral RNA-dependent RNA polymerases.

PLoS Pathogens, 2022
Cassava brown streak disease (CBSD), dubbed the "Ebola of plants", is a serious threat to food security in Africa caused by two viruses of the family Potyviridae: cassava brown streak virus (CBSV) and Ugandan (U)CBSV.

Influence of Olfaction in Host-Selection Behavior of the Cassava Whitefly Bemisia tabaci

Frontiers in Ecology and Evolution, 2021
Cassava is a vital food-security crop in Sub-Saharan Africa. Cassava crops are, however, severely affected by viral diseases transmitted by members of the whitefly species complex Bemisia tabaci.

Variation in Quantitative Resistance Components to the Fungus Pseudocercospora fijiensis Causing Black Leaf Streak Disease Among Banana Genotypes

Plant Pathology, Volume 74, Issue 9, Page 2857-2879, December 2025.
We assessed the quantitative resistance components of different banana genotypes to the fungus Pseudocercospora fijiensis causing black leaf streak disease in field and controlled conditions. ABSTRACT Combining different components of quantitative resistance in new banana hybrids has potential for developing efficient and durable control of black leaf ...

miR398‐Dirigent Module Negatively Regulates Cassava Resistance to Cassava Common Mosaic Virus by Affecting the Cell Wall Lignification and Thickness

Molecular Plant Pathology, Volume 26, Issue 10, October 2025.
miR398‐Dirigent module reduces cell wall lignification in cassava, weakening resistance to cassava common mosaic virus. Overexpressing Dir increases cell wall lignification and enhances resistance. ABSTRACT Studies have demonstrated microRNA398 (miR398) hyperaccumulation in plant species infected with viruses; however, its role in a viral context ...

Global Cassava Germplasm Resources: Industrial and Technological Development

Food and Energy Security, Volume 14, Issue 5, September/October 2025.
ABSTRACT The main cassava‐producing regions include Africa, South America, Southeast Asia, and China. Due to significant differences in natural environments, industrial backgrounds, and technological resources for germplasm development across these regions, the utilization of cassava germplasm resources shows regional variation.
