Sprayable solutions containing sticky rice oil droplets reduce western flower thrips damage and induce changes in leaf chemistry.

Thrips are one of the most challenging pests in agricultural crops, including . In this study we tested via two plant assays whether solutions containing sticky rice germ oil (RGO) droplets could effectively trap thrips and lower thrips damage on . In the first assay, we additionally assessed the metabolomic effects of these RGO droplet sprays and thrips presence on plant chemistry via H NMR and headspace GC-MS on multiple timepoints to investigate which plant metabolites were affected by spraying and their potential relation to plant resistance against thrips.

Isolation and Identification of Coumarins from Citrus latifolia Leaves Using Advanced Chromatographic Techniques.

Coumarins are a class of natural compounds that exhibit a wide range of biological activities, which include anticoagulant, anti-inflammatory, anticancer, and antimicrobial effects. This class of compounds has drawn considerable interest in recent years. The exploration of such properties contributes to our understanding of the potential of coumarins as valuable agents in various clinical applications.

Dissecting negative effects of two root-associated bacteria on the growth of an invasive weed.

Plant-associated microorganisms can negatively influence plant growth, which makes them potential biocontrol agents for weeds. Two Gammaproteobacteria, Serratia plymuthica and Pseudomonas brassicacearum, isolated from roots of Jacobaea vulgaris, an invasive weed, negatively affect its root growth. We examined whether the effects of S.

Cultivar-dependent phenotypic and chemotypic responses of drug-type L. to polyploidization.

L. is a plant with a wide range of potential medicinal applications. In recent years, polyploidy has gained attention as a potential strategy for rapidly improving , which, unlike other modern crops, has not yet benefitted from this established biotechnological application.

Metabolomic Investigation of and the Putative Role of Coumarins in Resistance to Black Spot Disease.

Citrus black spot (CBS) is a disease caused by the fungus that affects citrus plants, causing fruit blemish and premature drop that result in severe economic losses in commercial citrus orchards. However, CBS symptoms and effects may vary depending on the citrus species: (lemon) is susceptible and highly affected by the disease, while no CBS-related damage has ever been observed for (Tahiti lime), implying that it must be resistant to the disease. The difference in the response to this disease provided the opportunity to gain insight into the metabolites responsible for the resistance by comparison of the metabolomic profiles of these two citrus species.
