Ontogenic variations in n-alkanes during somatic embryogenesis of flax (Linum usitatissimum L.) [PDF]

open access: yes, 2001
Hypocotyl segments of flax seedlings germinated in vitro, were used to induce indirect somatic embryogenesis on solid medium. The composition and distribution of n-alkanes in flax tissues collected at different developmental stages were studied by GC and

Spatial Cell Death and Oxidative Stress Dynamics in Gas Plasma‐Treated Tumor Tissues

open access: yesAdvanced NanoBiomed Research, EarlyView.
Schematic representation of the four experimental models to study tissue penetration and oxidation. Four tissue models were used. Human pancreatic cancer cells were grown on the chorioallantois membrane of chicken embryos and gas plasma‐treated in ovo, murine colorectal tumor tissue was gas plasma‐exposed ex vivo, murine squamous cell carcinoma cells ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Environmental Transformation and Trophic Transfer of Engineered Nanomaterials in the Agri‐Food Chain and Implications for human Health

open access: yesChemFoodChem, EarlyView.
ABSTRACT Engineered nanomaterials (ENMs) are increasingly applied in agriculture to improve crop yield, nutrient efficiency, and food quality. This study examines the environmental transformation of ENMs, their uptake in plants, and their transfer across the agri‐food chain leading to human exposure.

Leaf cuticular wax composition of a genetically diverse collection of lettuce (Lactuca sativa L.) cultivars evaluated under field conditions

open access: yesHeliyon
Cuticular waxes of plants impart tolerance to many forms of environmental stress and help shed dangerous human pathogens on edible plant parts. Although the chemical composition of waxes on a wide variety of important crops has been described, a detailed

Influence of Nanomaterials and Nanocomposites on the Nutrient Composition

open access: yesFood Safety and Health, EarlyView.
Nanomaterials and nanocomposites enhance crop nutrition and food quality by improving nutrient availability, plant uptake, and bioavailability through controlled delivery and nano‐encapsulation. Their applications in agriculture and food systems enable sustainable biofortification, improved preservation, and functional foods, while emphasizing safety ...

Navigating the future of nano‐pesticides: A perspective on design, efficacy, mechanisms, and environmental stewardship

open access: yesiMeta, EarlyView.
Nano‐pesticides are driving a paradigm shift toward sustainable plant protection. This review systematically synthesizes recent advances across four interconnected domains: (i) intelligent formulation design for targeted delivery and controlled release; (ii) interfacial behavior regulation to enhance foliar deposition; (iii) multi‐omics elucidation of ...

Leaf Optical Responses to Light and Soil Nutrient Availability in Temperature Deciduous Trees [PDF]

open access: yes, 2005
Leaf optical parameters influence light availability at the cellular, leaf, and canopy scale of integration. While recent studies have focused on leaf optical responses to acute plant stress, the effects of changes in plant resources on leaf optics ...

Foliar lead uptake by lettuce exposed to atmospheric fallouts [PDF]

open access: yes, 2010
Metal uptake by plants occurs by soil−root transfer but also by direct transfer of contaminants from the atmosphere to the shoots. This second pathway may be particularly important in kitchen gardens near industrial plants.
