Ecological Relevance of the Degradation Processes of Allelochemicals

, 2007
Some considerations are made here on the ecological relevance of the degradation processes of allelochemicals, concerning the activity of some of the degradation products produced in soil.

Allelopathic and Bloom-Forming Picocyanobacteria in a Changing World

Toxins, 2018
Picocyanobacteria are extremely important organisms in the world’s oceans and freshwater ecosystems. They play an essential role in primary production and their domination in phytoplankton biomass is common in both oligotrophic and eutrophic waters ...

Reduction in litter allelochemicals promotes positive biotic interactions among alien species

Functional Ecology, Volume 40, Issue 9, Page 2932-2945, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract A key focus of invasion ecology is elucidating why multiple alien species accumulate within ecosystems. The invasional meltdown hypothesis proposes that one alien invader promotes further invasions through soil legacy effects.

Allelochemicals: Role in Plant-Environment Interactions

, 2009
During evolution, the plants developed new biosynthetic pathways to produce secondary metabolites (flavonoids, alkaloids, cyanogenic glycosides, glucosinolates, phenolics and tannins) known as allelochemicals.

Sesquiterpene Lactones Isolated from Centaurea cineraria L. subsp. cineraria Inhibit the Radicle Growth of Broomrape Weeds

Plants
The plant Centaurea cineraria L. subsp. cineraria has been investigated as a potential source of inhibitors of broomrape radicle growth. The latter are weeds that pose a threat to agriculture and for which there are few methods available for the control ...

Evaluation of Biological Response of Lettuce (Lactuca sativa L.) and Weeds to Safranal Allelochemical of Saffron (Crocus sativus) by Using Static Exposure Method

Molecules, 2019
Safranal, the main volatile chemical of Saffron (Crocus sativus) was studied to estimate its allelopathic effects on the photosynthetic pigment chlorophyll, leaf electrolyte leakage, fresh weight, catalase (CAT), and peroxidase (POX) activity of the test

Systemic acquired resistance: an emerging role for jasmonates in local signal biogenesis, translocation and distal signal decoding

New Phytologist, Volume 251, Issue 6, Page 3142-3158, September 2026.
Jasmonate signalling underpins establishment of plant systemic acquired resistance (SAR). Activation of the hypersensitive response (HR) not only contains the pathogen but establishes broad spectrum resistance in unchallenged leaves. The strong burst of reactive oxygen/nitrogen species initiating the HR results in lipid peroxidation (illustrated by ...

Hormesis and Antagonism in Low-Dose Phalaris Allelochemicals during Microcystis Control [PDF]

Aquatic ecosystems face significant challenges globally from cyanobacterial blooms. Phalaris arundinacea (Reed Canary Grass) is used in artificial wetlands and found in natural wetlands. We investigated whether allelochemicals released from Phalaris root

Functional Effects of the Pioneer Fern Dicranopteris on Soil Fertility and Its Spatial Patterns in Degraded Hilly Landscapes

Land Degradation &Development, Volume 37, Issue 14, Page 10340-10354, 30 August 2026.
ABSTRACT Vegetation recovery is vital for reversing soil degradation in subtropical red soil regions. This study evaluates the role of the pioneer fern Dicranopteris in enhancing soil fertility and its spatial variability across degraded hills in South China.

Plant strategies of manipulating predator-prey interactions through allelochemicals: prospects for application in pest control. [PDF]

, 1990
To understand the role of allelochemicals in predator-prey interactions it is not sufficient to study the behavioral responses of predator and prey. One should elucidate the origin of the allelochemicals and be aware that it may be located at another ...
