Allelochemicals and their importance [PDF]

Allelochemicals are secondary plant metabolites capable of influencing the growth, development, and metabolism of other plants, microorganisms, or insects in their immediate environment. These substances are a key mechanism in the phenomenon of allelopathy, which refers to chemical interactions between organisms that can be either positive or negative.

Antimicrobial Activity of Catechol and Pyrogallol as Allelochemicals

Zeitschrift für Naturforschung C, 2006
Abstract Catechol and pyrogallol are allelochemicals which belong to phenolic compounds synthesized in plants. Their antimicrobial activities were investigated on three bacteria (Pseudomonas putida, Pseudomonas pyocyanea, Corynebacterium xerosis) and two fungi (Fusarium oxysporum, Penicillium italicum) phytopathogenic species as test ...

Phytotoxic Effects of Ethanolic Extracts of Magonia pubescens A.St.-Hil. (Sapindaceae) on the Germination of Emilia sonchifolia (L.) DC. Seeds. [PDF]

Chem Biodivers
Ethanolic extracts from Magonia pubescens exhibit concentration‐dependent allelopathic activity against Emilia sonchifolia. Leaf extracts strongly inhibit seed germination and seedling growth, surpassing glyphosate under the tested conditions, whereas intermediate concentrations stimulate germination, indicating hormesis.

Stability studies of cynaropicrin-major sesquiterpene lactone of Cynara cardunculus leaves. [PDF]

Pest Manag Sci
This study investigated its stability under high temperature and pH, mimicking agronomic extremes and under soil context. Bioassays demonstrated that degradation products exhibited higher phytotoxic activity than cynaropicrin and deacylcynaropicrin. This is the first study about cynaropicrin's stability, characterizing degradation products, and their ...

The regulation of three new members of the cytochrome P450 CYP6 family and their promoters in the cotton aphid Aphis gossypii by plant allelochemicals [PDF]

, 2018
BACKGROUND: The expression of P450 genes in insects can be induced by plant allelochemicals. To understand the induction mechanisms, we measured the expression profiles of three P450 genes and their promoter activities under the induction of plant ...

Saturated and unsaturated fatty acids as potential allelochemicals for aquatic ecosystems rehabilitation

, 2023
Cyanobacterial blooms (HCBs) in water bodies adversely affect aquatic ecosystems. In laboratory experiments, metabolites-allelochemicals of aquatic macrophytes, nonanoic – a monobasic saturated and palmitoleic – an Omega-7 monounsaturated fatty acids ...
