Maize Lethal Necrosis disease: review of molecular and genetic resistance mechanisms, socio-economic impacts, and mitigation strategies in sub-Saharan Africa

BMC Plant Biology, 2022
Background Maize lethal necrosis (MLN) disease is a significant constraint for maize producers in sub-Saharan Africa (SSA). The disease decimates the maize crop, in some cases, causing total crop failure with far-reaching impacts on regional food ...

Bi‐Functional Topospecific Nanoparticles to Promote Immune‐Tumor Cell Engagement as A New Immunotherapeutic Strategy

Advanced Materials, EarlyView.
A Janus‐engineered nanoplatform (J‐pHLIP‐PD1), featuring separate tumor‐ and immune‐targeting faces, bridges melanoma cells and cytotoxic T lymphocytes using toposelective pHLIP and anti‐PD‐1 presentation. This strategy elicits robust antitumor responses, promotes immunogenic tumor cell death, suppresses lung metastasis in vivo, and provides a modular,

Genetic Dissection of Resistance to Gray Leaf Spot by Combining Genome-Wide Association, Linkage Mapping, and Genomic Prediction in Tropical Maize Germplasm

Frontiers in Plant Science, 2020
Gray leaf spot (GLS) is one of the major maize foliar diseases in sub-Saharan Africa. Resistance to GLS is controlled by multiple genes with additive effect and is influenced by both genotype and environment.

Gradients of Aliveness and Engineering: A Taxonomy of Fungal Engineered Living Materials

Advanced Materials, EarlyView.
This paper explores the potential of fungal engineered living materials (ELMs), examining fungal biology and growth mechanisms, which underpin their development. It presents a classification framework based on aliveness, scaffold composition, and engineering degree. Unique properties such as self‐healing, biosensing, and bioremediation are highlighted,

Genome-Wide Association Analyses Identify QTL Hotspots for Yield and Component Traits in Durum Wheat Grown under Yield Potential, Drought, and Heat Stress Environments

Frontiers in Plant Science, 2018
Understanding the genetic bases of economically important traits is fundamentally important in enhancing genetic gains in durum wheat. In this study, a durum panel of 208 lines (comprised of elite materials and exotics from the International Maize and ...

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

Advanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Transparent, Sprayable Plastic Films for Luminescent Down‐Shifted‐Assisted Plant Growth

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
Spreading the light: A modular approach to down‐shifting europium‐containing polyoxotitanium luminescent cages is developed, allowing their incorporation into sprayable plastic coatings on agricultural greenhouses for accelerated plant growth. Abstract The world's steadily growing population and global heating due to climate change are a threat to food

Exotic alleles contribute to heat tolerance in wheat under field conditions

Communications Biology, 2023
Comparative phenotyping and genome-wide association study in a panel of 149 wheat genotypes reveal alleles associated with heat tolerance, which could be useful in future breeding programmes for wheat cultivars.
