Allelopathic potential and allelochemical composition in different soil layers of Rhododendron delavayi forest, southwest China

open access: yesFrontiers in Ecology and Evolution, 2022
Forests habituated by Rhododendron delavayi often lack understory vegetation, which could possibly be a consequence of allelopathy. It is a phenomenon by virtue of which certain plant species produce allelochemicals that affect the growth and behavior of

Evaluation of Agave angustifolia as a Sustainable Alternative to Synthetic Pesticides: Phytochemical Composition and Multi‐Trophic Bioactivity

open access: yesFlavour and Fragrance Journal, EarlyView.
The pesticidal potential of Agave angustifolia by assessing its anti‐nematic, antimicrobial, and insecticidal activities, alongside phytochemical profiling. ABSTRACT Plant diseases caused by fungi, bacteria, nematodes, and viruses contribute significantly to annual crop losses and economic hardship. Reliance on chemical pesticides, over a thousand used

Isolation of Allelochemicals from Rhododendron capitatum and Their Allelopathy on Three Perennial Herbaceous Plants

open access: yesPlants
Rhododendron capitatum community expansion is a major threat to alpine meadow. Allelopathy is an important mediator in managing relationships between plants in natural ecosystems. However, allelopathy and specific allelochemicals of R. capitatum have not

Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.

open access: yesPest Management Science, EarlyView.
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

Durum wheat and allelopathy: towards wheat breeding for natural weed management

open access: yesFrontiers in Plant Science, 2013
Wheat-derived foodstuffs represent about one-fifth of the calories consumed by humans worldwide. Bread wheat (Triticum aestivum L.) is one of the most important crops throughout the world, and it has been extensively studied for its allelopathic ...

Mycorrhizal identity of neighbouring trees shapes seedling survival and plant–soil feedbacks through trait and light interactions

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant–soil feedbacks (PSF) play a central role in determining forest community dynamics, with trees associated with arbuscular mycorrhizal fungi (AMF) often experiencing negative PSFs, while those associated with ectomycorrhizal fungi (EMF) experience positive PSFs ...

The Role of Silicon in Antiherbivore Phytohormonal Signalling

open access: yesFrontiers in Plant Science, 2019
The role of plant silicon (Si) in the alleviation of abiotic and biotic stress is now widely recognised and researched. Amongst the biotic stresses, Si is known to increase resistance to herbivores through biomechanical and chemical mechanisms, although ...

Distinct Defence Mechanisms of Allelopathic Rice Against Quinclorac‐Susceptible and ‐Resistant Barnyardgrass: Involvement of Specific Metabolites and Rhizosheath Microbiota

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Allelopathic rice is increasingly recognised as a promising strategy for sustainable weed management. Resistance to the herbicide quinclorac is widespread in barnyardgrass, but it remains unclear whether allelopathic rice exerts the same defence against herbicide‐susceptible and ‐resistant barnyardgrass. We conducted integrated transcriptomic,
