Response of Maize, Pea and Radish Roots to Allelochemical Stress [PDF]

open access: yes, 2011
We examined whether allelochemical stress leads to increased lipoxygenase activity in roots of sweet maize (Zea mays L. ssp. saccharata), pea (Pisum sativum L.) and radish (Raphanus sativum L. var. radicula).

Toxicity of meta-Tyrosine

open access: yesPlants, 2021
L-Tyrosine (Tyr) is one of the twenty proteinogenic amino acids and also acts as a precursor for secondary metabolites. Tyr is prone to modifications, especially under conditions of cellular redox imbalance.

Allelopathic potential and allelochemical composition in different soil layers of Rhododendron delavayi forest, southwest China

open access: yesFrontiers in Ecology and Evolution, 2022
Forests habituated by Rhododendron delavayi often lack understory vegetation, which could possibly be a consequence of allelopathy. It is a phenomenon by virtue of which certain plant species produce allelochemicals that affect the growth and behavior of

Do germination indices adequately reflect allelochemical effects on the germination process?

open access: yes, 2022
Allelopathy is often demonstrated by testing allelochemical effects on germination using many germination indices to assess them. The objective of this work was to compare four common germination indices (G(T), S, AS, and CRG) previously calculated with ...

Efficiency of Glutinous Rice Straw Extracts (RD-Six) and Water Hyacinth in Inhibiting Algal Growth and Reducing Nutrients from a Hyper-eutrophic Pond

open access: yesEnvironment and Natural Resources Journal, 2021
Eutrophication is one of the main water pollution problems, which occurs throughout Thailand. This research focused on the use of glutinous rice straw (RD-Six) extract and water hyacinth to reduce nutrients and to inhibit ...

Soil and compost humic fractions regulate the response of Sclerotinia sclerotiorum to exogenously added allelochemical compounds.

open access: yes, 2014
Allelochemical compounds released by plants to signal their presence and needs interact in soils with very important macromolecules, such as humic acids (HAs), which are able to modulate the ultimate effects on target organisms. Most of the available

Sex Differences in Mouse Exploratory Behaviour to Fel d 1, a Cat ABP-Like Protein

open access: yesAnimals, 2021
Fel d 1 is a cat protein abundantly released and found in their habitat and is closely related to mouse androgen-binding proteins (ABPs). We hypothesized that mice have developed chemical communication mechanisms to detect and avoid this protein.
