A critical reassessment of the novel weapons hypothesis and allelopathy as an adaptive strategy that facilitates plant invasion. [PDF]

New Phytol
Summary Plants have evolved an assortment of chemical adaptations that integrate environmental cues with developmental processes to regulate growth and reproduction. A subset of these phytochemicals may be considered allelopathic adaptations if they enhance fitness by suppressing competition for limiting resources.

Allelopathic Activity of Strigolactones on the Germination of Parasitic Plants and Arbuscular Mycorrhizal Fungi Growth

Agronomy, 2021
Strigolactones (SLs) are a prime example of allelochemicals, promoting parasitic plant germination and certain hyphal branching factors associated to the growth of symbiotic arbuscular mycorrhizal fungi (AMF).

Synthesis of Benzoxazinones Sulphur Analogs and Their Application as Bioherbicides: 1.4-Benzothiazinones and 1.4-Benzoxathianones for Weed Control

Agronomy, 2023
Eight different compounds inspired by benzoxazinones were synthesized in one simple step with easy purification. These compounds have a sulfur atom instead of the oxygen atom present in benzoxazinones.

Bioactive Diterpenes from the Brazilian Native Plant (Moquiniastrum pulchrum) and Their Application in Weed Control

Molecules, 2021
Even today, weeds continue to be a considerable problem for agriculture. The application of synthetic herbicides produces serious environmental consequences, and crops suffer loss of their activity due to the appearance of new resistant weed biotypes ...

Potential phytotoxic and shading effects of invasive Fallopia (Polygonaceae) taxa on the germination of dominant native species [PDF]

, 2011
Two species of the genus Fallopia (F. sachalinensis, F. japonica, Polygonaceae) native to Asia, and their hybrid (F. ×bohemica), belong to the most noxious plant invaders in Europe.

Steroidal Saponins with Plant Growth Stimulation Effects; Yucca schidigera as a Commercial Source

Plants, 2022
Plant growth-stimulation bioactivity of triterpenoid saponins is well known, especially for oleanane-type compounds. Nevertheless, a few phytotoxicity bioassays performed on some steroidal saponins have shown hormesis profiles and growth stimulation on ...

Sources and modes of action of invasive knotweed allelopathy : the effects of leaf litter and trained soil on the germination and growth of native plants [PDF]

, 2012
Invasive knotweeds, native to Eastern Asia, are among the most dominant plant invaders of European and North American temperate ecosystems. Recent studies indicate that one cause of this dominance might be allelopathy, but the possible sources and modes ...
