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

Long‐Term Legacy of Exotic Pioneers: Over Two Decades of Biodiversity Monitoring Reveals Constrained Succession in a Restored Sanitary Landfill

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Long‐term ecological studies are critical for evaluating restoration strategies on challenging sites, such as closed landfills. This study presents a 23‐year biodiversity monitoring program (2000–2023) at the restored Southeast New Territories sanitary landfill in Hong Kong.

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

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

open access: yesPest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Allelochemicals from Plants as Herbicides

open access: yes, 1988
Allelochemicals representing numerous chemical groups have been isolated from over 30 families of terrestrial and aquatic plants. Some of the compounds also have been isolated from soil in quantities sufficient to reduce plant growth.
