Artemisia species, widespread in nature, are frequently utilized for the treatment of diseases such as malaria, hepatitis, cancer, inflammation, and infections by fungi, bacteria, and viruses. Furthermore, some Artemisia constituents were found to be potential insecticides and allelopathic chemicals. This genus is receiving growing attention presumably due to: (i) the diversified biology and ch...

Allelopathy has been recently suggested as a mechanism by which macroalgae may outcompete corals in damaged reefs. Members of the brown algal genus Lobophora are commonly observed in close contact with scleractinian corals and have been considered responsible for negative effects of macroalgae to scleractinian corals. Recent field assays have suggested the potential role of chemical mediators i...

Sunflower broomrape is a noxious parasitic weed which has caused severe damage to crop ecosystems. Trap crops can release a mixture of allelochemicals to induce the germination of sunflower broomrape. We studied the allelopathic effects of soybean on sunflower broomrape. Fourteen common soybean cultivars were grown in pots. Samples were collected from soybean plants and rhizosphere soil at five...

Investigation of allelopathic substances from herbal plants may lead to the development allelochemical-based natural herbicides. Croton oblongifolius (Roxb.) is a well-known plant with long history being used for traditional medicines and source diverse range bioactive compounds. This has been reported have potential; however, its allelopathic-related not yet described. Therefore, we conducted ...

Biotic interactions in the plankton can be both complex and dynamic. Competition among phytoplankton is often chemically mediated, but no studies have considered whether allelopathic compounds are modified by biotic interactions. Here, we show that compounds exuded during Karenia brevis blooms were allelopathic to the cosmopolitan diatom Skeletonema costatum, but that bloom allelopathy varied d...

For aquatic systems, studies on allelopathic interactions among phytoplankton have increased over recent years, with the main focus on the role of the donor organism. In this study, we report on the response of a target organism to allelochemicals and whether this response was affected by stress conditions (nutrient limitation). We exposed the diatom Thalassiosira weissflogii, grown under diffe...

We investigated the nitrogen and phosphate nutrient status in the habitats of Alternanthera philoxeroides and its co-occurring algal growth in a field survey. We also determined the algicidal activity of A. philoxeroides extracts from a diversity of habitats in Chaohu Lake, China, in the laboratory. We then tested the correlation between the nutrient status and the algicidal activity of A. phil...
