“…Hence, this leads to the inhibition of the pathogenicity of F. oxysporum. These proteins are vital elements of the pathway of a transduction signal that controls numerous F. oxysporum infection processes [33]. Several studies have explained the importance of specific pathogenicity proteins, e.g., FMK1, SET7, SET12, AreA, MeaB, Rho1, MKK1,2, SEG1, XINR, and Hog, in various pathways that are responsible for the virulence of F. oxysporum and that have a role in disease control [18,35].…”

“…The injector temperature was 250 • C. The flow rate of the carrier gas (helium) was 1.41 mL/min. The mass spectra were recorded according to the following conditions: filament emission current (equipment current), 60 mA; ionization voltage, 70 eV; ion source, 200 • C. Diluted samples (1% v/v) were injected via the split mode (split ratio: 1:15) [33].…”

Background: The present study investigated the antifungal activity and mode of action of four Olea europaea leaf extracts, Thymus vulgaris essential oil (EO), and Boswellia carteri EO against Fusarium oxysporum. Methods:Fusarium oxysporum Lactucae was detected with the internal transcribed spacer (ITS) region. The chemical compositions of chloroform and dichloromethane extracts of O. europaea leaves and T. vulgaris EO were analyzed using GC-MS analysis. In addition, a molecular docking analysis was used to identify the expected ligands of these extracts against eleven F. oxysporum proteins. Results: The nucleotide sequence of the F. oxysporum Lactucae isolate was deposited in GenBank with Accession No. MT249304.1. The T. vulgaris EO, chloroform, dichloromethane and ethanol efficiently inhibited the growth at concentrations of 75.5 and 37.75 mg/mL, whereas ethyl acetate, and B. carteri EO did not exhibit antifungal activity. The GC-MS analysis revealed that the major and most vital compounds of the T. vulgaris EO, chloroform, and dichloromethane were thymol, carvacrol, tetratriacontane, and palmitic acid. Moreover, molecular modeling revealed the activity of these compounds against F. oxysporum. Conclusions: Chloroform, dichloromethane and ethanol, olive leaf extract, and T. vulgaris EO showed a strong effect against F. oxysporum. Consequently, this represents an appropriate natural source of biological compounds for use in healthcare. In addition, homology modeling and docking analysis are the best analyses for clarifying the mechanisms of antifungal activity.

“…The excessive and indiscriminate use of available pesticides to control the losses of stored crops and to reduce insect-borne diseases as malaria, filaria and trypanosomiasis induced disturbances in ecosystem functioning [1,2]. Moreover, synthetic fungicides and fungal-drugs utilization to treat environmental and animal molds are not in a lesser class, when we talk about the negative effects and the appearance of fungicide-resistant pathogens [3,4]. Therefore, there is an increasing concern to search for new highly selective and eco-friendly alternatives of beneficial pest control materials to feed the growing human population in a healthy environment.…”

The present investigation was focused on the study of the chemical composition variability and biological activities of the essential oils from Clinopodium nepeta subsp. nepeta and subsp. glandulosum. Essential oils extraction was performed using hydrodistillation and the separation of the constituents was carried out by gas chromatography coupled with mass spectrometry (GC-MS). Antifungal activities were tested against Aspergillus flavus, Aspergillus terreus, Microsporum canis, Microsporum gypseum, Trichophyton mentagrophytes, and Candida albicans. Toxicity and repellency were evaluated against the stored product pests Tribolium confusum and Sitophilus zeamais. Both essential oils were characterized by a high content of oxygenated monoterpenes. Piperitone ranks first in the subspecies nepeta and piperitenone oxide is the dominant constituent in the subspecies glandulosum. All tested samples displayed noteworthy antifungal properties, with the highest activity observed for the essential oil of C. nepeta subsp. glandulosum, collected in Béni-M’tir, against T. mentagrophytes (MIC = 40 µg/mL). The essential oil samples of C. nepeta subsp. glandulosum were strongly repellent to the insect species (PR > 80%, after 2h) and highly toxic to S. zeamais reaching 97.5%–100% mortality after 24 h of exposure. In conclusion, this study showed considerable intra-specific changes in the quality of C. nepeta essential oils, which is reflected in different rates of antifungal and insecticidal activity.

Introduction Medicinal plants have been used in healthcare since time immemorial, as have their therapeutic activities and the production of plant‐based medicines. Objectives This study aims to use gene‐targeted molecular markers for genetic diversity analysis of 16 medicinal plants. Besides, phytochemical analysis antibacterial and antifungal activities of some medicinal plant extracts commonly used in Egypt are compared to major compounds. Methods DNA‐based classification of 16 medicinal species using Conserved DNA‐Derived Polymorphism (CDDP) and Start Codon Targeted (SCoT) primers. Three species representing three orders (Pelargonium graveolens, Matricaria chamomilla, and Hyoscyamus muticus were analysed [high‐performance liquid chromatography (HPLC), gas chromatography‐mass spectrometry (GC‐MS)] and evaluated for their antibacterial and antifungal activities against (Escherichia coli O157: H7 ATCC 93111, Salmonella typhimurium ATCC 14028, Methicillin‐resistant Staphylococcus aureus (MRSA) ATCC 43300, Bacillus ceruse ATCC 33018, and Sclerotinia sclerotiorum in comparison with some of their antimicrobial components. Results Our results revealed 309 and 349 polymorphic bands with 100% polymorphism. Among them, 51 and 57 were unique loci for CDDP and SCoT, respectively. The 16 species were categorised into three groups depending on the similarity matrix. The results of antibacterial and antifungal activities revealed that Pelargonium oil showed significant antifungal and antibacterial activities against the tested pathogens. Gallic acid severely reduced all tested bacteria's growth, but atropine severely reduced the growth of the B. ceruse only. Molecular modelling revealed their activity against sclerotium development. Conclusion The gene‐targeted marker techniques were highly useful tools for the classification of the 16 medicinal plant species, despite displaying high similarities at morphological and phytochemical analyses but, have antifungal and antibacterial activities.
