Defensive role of allelopathic secondary compounds in plants: a review of data on two independent general hypotheses [PDF]

open access: yes, 2018
This review examines and whenever appropriate, reanalyses published literature related to two general and independent hypotheses having the underlying assumption that phytoactive secondary compounds produced by plants evolved primarily as plant defences ...

Allelochemicals and Signaling Chemicals in Plants [PDF]

open access: yesMolecules, 2019
Plants abound with active ingredients. Among these natural constituents, allelochemicals and signaling chemicals that are released into the environments play important roles in regulating the interactions between plants and other organisms. Allelochemicals participate in the defense of plants against microbial attack, herbivore predation, and/or ...

Ecological and genomic variation in ectomycorrhizal fungal exploration types

open access: yesNew Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

The search for exudates from Eurasian watermilfoil and hydrilla [PDF]

open access: yes, 2002
Secondary metabolites are produced by aquatic plants, and in some instances, exudation of these metabolites into the surrounding water has been detected.

Effects of Aspen Phenolic Glycosides on Gypsy Moth (Lepidoptera: Lymantriidae) Susceptibility to \u3ci\u3eBacillus Thuringiensis\u3c/i\u3e [PDF]

open access: yes, 2017
Performance of the gypsy moth, Lymantria dispar, on quaking aspen, Populus tremuloides, is strongly affected by foliar concentrations of phenolic glycosides.

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,

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

Biological management of allelopathic plant Parthenium sp.

open access: yesOpen 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.

Allelopathic Observations in Rice (Oryza sativa L.) to Ducksalad (Heteranthera limosa) [PDF]

open access: yes, 1989
More than 50 weed species infest drill-seeded rice in the U.S. and one of the most prevalent aquatic weeks is ducksalad (Heteranthera limosa). During the summer of 1988, a field experiment was conducted to identify rice accessions from the USDA/ARS rice ...

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...
