Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Uganda

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the likelihood of pest freedom at entry in the EU, including both regulated and non‐regulated pests, potentially associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Uganda.

Knowledge on cassava disease management: The case of cassava brown streak disease awareness in Northern Uganda [PDF]

African Journal of Plant Science, 2013
The cassava brown streak disease (CBSD) has spread rapidly in Northern Uganda since its emergence in Uganda in 2005. Field surveys conducted in 2010 and 2011 by Ngetta Zonal Agricultural Research and Development Institute (Ngetta ZARDI) revealed high CBSD prevalence in the zone.

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

Progress and Impacts of “Omics” Technologies in Understanding the Drought Response in Cassava: Adoption for Food Security in Africa

Plant-Environment Interactions, Volume 6, Issue 6, December 2025.
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

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 ...
