Foliar application of the triterpene derivative 24-methylen-elemo-lanosta-8,24-dien-3-one alleviates salt toxicity in grapevine

This work focused on the effect triterpene derivative 24-methylen-elemo-lanosta-8,24-dien-3-one (F3) on the induction of salt stress tolerance of the Moroccan grapevine cv. “Doukkali”. Hardwood

Conventional Medicinal Uses, Phytoconstituents, and Biological Activities of Euphorbia officinarum L.: A Systematic Review

This review aims to cover E. officinarum taxonomy, botanical description, distribution, conventional uses, and phytochemical compounds of this plant, including the biological activities of compounds isolated and of these semisynthesized compounds.

Induced resistance to wild fire disease of Nicotiana benthamiana using seed treated with triterpene derivatives from Euphorbia

Analysis of plant defense markers revealed that H2O2 and guaiacol peroxidase were only slightly activated but were primed after pathogen infiltration, underline the duality of the mode of action of the triterpenic compounds and suggest their use as plant defense inducers in crop protection.

Opportunities and Challenges in Studies of Host-Pathogen Interactions and Management of Verticillium dahliae in Tomatoes

The current knowledge on the race and population structure of V. dahliae is discussed, including pathogenicity factors, host genes, proteins, enzymes involved in defense, and the emergent management strategies and future research directions for managing Verticillium wilt in tomatoes are discussed.

Plant-Derived Protectants in Combating Soil-Borne Fungal Infections in Tomato and Chilli

This review outlines PDPs’ critical functions (including formulations) in regulating soil-borne fungal diseases, keeping tomato and chilli pathogens in the spotlight, and emphasises the advantages of the in silico approach over conventional approaches for screening plants’ secondary metabolites with target-specific fungicidal activity.

Opportunities and Challenges to Understand Host-Pathogen Interactions and Management of Verticillium dahliae on Tomato

This review discusses and summarizes the recent findings on the race and population structure of V. dahliae; pathogenicity factors; host genes, proteins, and enzymes involved in defense; the emergent management strategies, and recent approaches to managing Verticillium wilt in tomatoes.

3D-QSAR, ADME-Tox, and molecular docking of semisynthetic triterpene derivatives as antibacterial and insecticide agents

The structure of the three new triterpene derivatives can be adopted as reference for the synthesis of antibacterial drugs and also in the development of insecticides.



Phytotoxicity of Triterpenes and Limonoids from the Rutaceae and Meliaceae. 5α,6β,8α,12α-Tetrahydro-28-norisotoonafolin – a Potent Phytotoxin from Toona ciliata

Limonoids showed phytotoxic activity and 5α,6β,8α,12α-tetrahydro-28-norisotoonafolin and gedunin were the most active, with bioactivity levels similar to, and in some cases better than, those of the commercial herbicide Logran.

Induced Resistance in Tomato Plants against Verticillium Wilt by the Binuclear Nickel Coordination Complex of the Ligand 2,5-Bis(pyridin-2-yl)-1,3,4-thiadiazole.

It is demonstrated that L and Ni2L2 can be considered as new activators of plant defense responses in controlling Verticillium wilt.

Duality of acibenzolar-S-methyl in the inhibition of pathogen growth and induction of resistance during the interaction tomato/vertcillium dahliae

The results suggest that ASM protects tomato from V. dahlia directly by inhibiting the growth of pathogen and indirectly by activating plant defenses responses.

Perception of Fungal Sterols in Plants (Subnanomolar Concentrations of Ergosterol Elicit Extracellular Alkalinization in Tomato Cells)

It is demonstrated that tomato cells perceive ergosterol with a selectivity and sensitivity that resembles the perception of steroid hormones in animals.

Isolation and Phytotoxicity of Terpenes from Tectona grandis

A study was carried out on the allelopathic potential of four forest species, Tectona grandis, Aleurites fordii, Gliricidia sepium, and Maytenus buxifolia, and a new compound, abeograndinoic acid, was isolated, and elucidation of its structure showed that this compound has an unusual carbon skeleton.

Pathogenicity and Vegetative Compatibility of Verticillium dahliae Kleb. Isolates from Olive in Morocco

Thirty-eight strains of Verticillium dahliae Kleb. from diseased olive stems originating from the most important regions of olive in Morocco, were tested by vegetative compatibility analysis to

Physiology and molecular aspects of Verticillium wilt diseases caused by V. dahliae and V. albo-atrum.

Although genetic resistance has been described in several plant species, only one resistance locus against Verticillium has been cloned to date and the molecular processes underlying this physiology remain largely unknown.

An Elicitor of the Hypersensitive Lignification Response in Wheat Leaves Isolated from the Rust Fungus Puccinia graminis f. sp. tritici II. Induction of Enzymes Correlated with the Biosynthesis of Lignin

The genuine biotic elicitor from germ tube walls of Puccinia graminis f. sp. tritici (Pgt-elicitor) induces lignification, preceded by an increase in phenylalanine ammonia-lyase (PAL) activity, when

Diversity, pathogenicity, and management of verticillium species.

This review focuses on Verticillium dahliae, placing emphasis on the controversy surrounding the elevation of a long-spored variant as a new species, recent advances in the analysis of compatible and incompatible interactions, highlighted by the use of strains expressing fluorescent proteins, and the genetic diversity among Verticills spp.
