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

Pest 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 ...

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

Geoderma
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

The role of arbuscular mycorrhizal fungi in the competition between invasive and native plants depends on the soil nitrogen form

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant invasion and nitrogen (N) deposition are escalating global change threats. Arbuscular mycorrhizal fungi (AMF) are increasingly recognized as critical mediators of plant invasion success, largely through their role in enhancing host nutrient acquisition.

The negative effects of an allelopathic invader on native plant photosynthesis are amplified after tree canopy closure

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many invasive plants produce antimicrobial allelopathic compounds that disrupt plant–fungal symbioses of native species in the communities they invade, influencing nutrient and water provisioning that support photosynthesis.

Biological management of allelopathic plant Parthenium sp.

Open Agriculture, 2020
Globally, weeds have been considered as a major threat and act as a hindrance to crop production, even though the farmers put tremendous efforts to eliminate the weeds to get a better yield.

Reduction in litter allelochemicals promotes positive biotic interactions among alien species

Functional Ecology, EarlyView.
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.

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

Insect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

Insect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.
