Image Analysis and Untargeted Metabolomics Reveal Potential Phytotoxins from Against Major Parasitic Weed (L.) Pomel.

Branched broomrape ( (L.) Pomel), an obligate parasitic weed with a wide host range, is known for its devasting effects on many crops worldwide. Soil fungi, notably sp.

Host-associated genetic differentiation and origin of a recent host shift in the generalist parasitic weed .

Branched broomrape, (L.) Pomel, is a globally distributed parasitic weed of economic importance. In Europe, where it is native, it can infest several crops, notably tomato, tobacco, and hemp.

Aggregation of magnetic nanoparticles functionalized with trans-resveratrol in aqueous solution.

In the framework of a protein-ligand-fishing strategy to identify proteins that bind to trans-resveratrol, a natural phenolic compound with pharmacological benefits, we have developed magnetic nanoparticles covalently linked to trans-resveratrol through three different derivatives and examined their aggregation behavior in aqueous solution. The monodispersed magnetic core (18 nm diameter) with its mesoporous silica shell (93 nm diameter) exhibited a notable superparamagnetic behavior useful for magnetic bioseparation. The hydrodynamic diameter, deduced from dynamic light scattering analysis, of the nanoparticle increased from 100 to 800 nm when the aqueous buffer changed from pH 10.

Screening for potential mycoherbicides within the endophyte community of Phelipanche ramosa parasitizing tobacco.

Branched broomrape (Phelipanche ramosa (L.) Pomel) is an achlorophyllous root parasitic plant with a wide host range. Its complex management is leading to the abandonment of tobacco or oilseed rape cultivation in the most affected regions in France.

Weeds Harbor an Impressive Diversity of Fungi, Which Offers Possibilities for Biocontrol.

The use of herbicides for weed control is very common, but some of them represent a threat to human health, are environmentally detrimental, and stimulate herbicide resistance. Therefore, using microorganisms as natural herbicides appears as a promising alternative. The mycoflorae colonizing different species of symptomatic and asymptomatic weeds were compared to characterize the possible mycoherbicidal candidates associated with symptomatic weeds.
