Identification of Potential Allelochemicals From Donor Plants and Their Synergistic Effects on the Metabolome of Aegilops geniculata

open access: yesFrontiers in Plant Science, 2020
The need for plants to defend themselves, communicate, and somehow contribute to the social life in their ecosystems has triggered the evolution of an astonishing number of diverse chemicals, some of which involved in plant–plant interactions.

Unraveling Sorghum Allelopathy in Agriculture: Concepts and Implications

open access: yesPlants, 2021
Allelopathy is an ecological phenomenon that involves the production and release of biomolecules from different crops, cultivated plants, and bacteria or fungi into the soil rhizosphere and impacts other organisms in the vicinity. Sorghum possesses vital

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Rhizosphere effects of Helianthus annuus and Hordeum vulgare on allelochemical sorption and degradation in soil

open access: yesGeoderma
Soil plays a crucial role in determining the activity of allelochemicals in natural and agricultural ecosystems. To identify potential differences in allelochemical availability and persistence between root-influenced soil (rhizosphere) and bulk soil, we

Dynamics of biotic resistance to plant invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Responses of a native plant species from invaded and uninvaded areas to allelopathic effects of an invader

open access: yesEcology and Evolution, 2019
Invaders exert new selection pressures on the resident species, for example, through competition for resources or by using novel weapons. It has been shown that novel weapons aid invasion but it is unclear whether native species co‐occurring with ...
