“…The literature reports supported these findings concerning other medicinal plants. Indeed, several studies have reported the chemical composition of LSEO, with some indicating that, in addition to the fenchone/camphor chemotypes, the chemical compositions of LSEO collected in Morocco and Greece contained 1,8-cineole and camphene, and α-cardinol, respectively, while others disclosed the presence of myrtenyl acetate, bornyl acetate, linalyl acetate, camphene, linalool, borneol, γ-terpinene, lavandulyl acetate, and caryophyllene as major compounds [ 10 , 18 , 43 , 44 , 45 , 46 ]. Besides the presence of some main compounds, our study clearly revealed the chemical composition quantitative and qualitative variability of L. stoechas plants collected from three different regions.…”

The aim of this study was the determination of the chemical compounds of Lavandula stoechas essential oil from Aknol (LSEOA), Khenifra (LSEOK), and Beni Mellal (LSEOB), and the in vitro investigation of their antibacterial, anticandidal, and antioxidant effects, and in silico anti-SARS-CoV-2 activity. The chemical profile of LSEO was determined using GC-MS-MS analysis, the results of which showed a qualitative and quantitative variation in the chemical composition of volatile compounds including L-fenchone, cubebol, camphor, bornyl acetate, and τ-muurolol; indicating that the biosynthesis of essential oils of Lavandula stoechas (LSEO) varied depending on the site of growth. The antioxidant activity was evaluated using the ABTS and FRAP methods, our results showed that this tested oil is endowed with an ABTS inhibitory effect and an important reducing power which varies between 4.82 ± 1.52 and 15.73 ± 3.26 mg EAA/g extract. The results of antibacterial activity of LSEOA, LSEOK and LSEOB, tested against Gram-positive and Gram-negative bacteria, revealed that B. subtilis (20.66 ± 1.15–25 ± 4.35 mm), P. mirabilis (18.66 ± 1.15–18.66 ± 1.15 mm), and P. aeruginosa (13.33 ± 1.15–19 ± 1.00 mm) are the most susceptible strains to LSEOA, LSEOK and LSEOB of which LSEOB exhibits bactericidal effect against P. mirabilis. furthermore The LSEO exhibited varying degrees of anticandidal activity with an inhibition zones of 25.33 ± 0.5, 22.66 ± 2.51, and 19 ± 1 mm for LSEOK, LSEOB, and LSEOA, respectively. Additionally, the in silico molecular docking process, performed using Chimera Vina and Surflex-Dock programs, indicated that LSEO could inhibit SARS-CoV-2. These important biological properties of LSEO qualify this plant as an interesting source of natural bioactive compounds with medicinal actions.

“…The antifungal and antibacterial effects of essential oils against fungi and bacteria that infect both humans and plants have been demonstrated by many studies. Additionally, new studies have revealed the antiphytoviral activities of essential oils against plant viruses, even though numerous studies have already shown their antiviral activities against viruses that infect humans and animals (Kalemba and Kunicka, 2003;Bozkurt et al, 2020;Ma and Yao, 2020;Wani et al, 2021;Parikh et al, 2021;Taglienti et al, 2022). There is not any study that discusses the docking technique of essential oils against plant viruses, despite the fact that several studies in the scientific literature demonstrate the antiviral potential of essential oils against viruses that infect humans using an in silico docking approach.…”

In 2021, a study was conducted in the Denizli region of Türkiye to investigate the phylogenetic relationship and presence of alfalfa mosaic alfamovirus (AMV) infecting pepper plants exhibiting viral disease symptoms. A total of 57 samples were collected, of which twenty-four tested positive for AMV with reverse transcriptase polymerase chain reaction (RT-PCR) assays. Samples from pepper plants displaying virus symptoms gave positive bands on the agarose gel, while healthy plants yielded negative results. One of the positive samples was randomly selected, cloned and sequenced. This sequence of the Denizli AMV isolate (753 bp) was recorded in the GenBank database with accession number OQ845956. The nucleotide sequence showed a high nucleotide consensus of 97%-99% compared with the nucleotide sequences of the same variants from different origins in GenBank. According to the phylogenetic tree generated through the Neighbour Joining (NJ) method, this AMV isolate belongs to the same group as Iranian isolates from various of hosts. Furthermore, in silico docking analysis of the coat protein (CP) of the AMV isolate and promising 12 essential oil compounds was performed to enable potential antiviral drug development. Docking study showed that eucalyptol, eugenol and carvacrol can make important contributions to the advancement of drug-based strategies for the managing of plant viruses by interacting with the virus coat protein of high binding energies, -5.3, -5.2 and -5.0 kcal mol-1, respectively. Although the presence of AMV in Denizli province has been reported previously, this study reports the phylogenetic relationships and docking analysis of the new AMV isolate in pepper crops.

“…on the stems Although all applications were found to be successful in suppressing the speck disease symptoms on the leaves and stem, Turf-Set, ISR-2000 and Sergomil applications were determined to be the most successful applications. In many studies, the antimicrobial activities of essential oils and nanoparticles have been also investigated against many plant pathogenic bacteria and it has been reported that they have high efficacies (Bozkurt et al, 2020;Şahin et al, 2021;Soylu et al, 2022;Şahin et al, 2022). Reduced phosphorus (P) compounds containing phosphite (Phi) have been investigated since the 1930s as potential sources to meet P requirements (MacIntire et.…”

This study tested the efficacy of five different phosphites (calcium, copper, magnesium, potassium and zinc/manganese phosphites) and a fungicide Fosetyl-Aluminum to inhibit bacterial speck disease severity caused by Pseudomonas syringae pv. tomato (Pst) on tomato leaves. The phosphites were applied at the recommended doses to the Pst inoculated plants in pots by foliar spraying at one-week intervals for a total of 4 weeks. The plants were kept in a controlled greenhouse under relative humidity (%75-90) and temperature (22-24 °C) until disease symptoms appeared in the control plants. Phosphites and Fosetyl-Aluminum inhibited the Pst symptoms on tomato leaves by 42.1-75.0% in the first and 22.8-90.3% in the second experiments. This study demonstrated the direct influence of phosphites on tomato bacterial speck. The study suggested that phosphites can be an effective alternative for the chemical control of tomato bacterial disease. The bacterial agent, Pst, causes bacterial speck disease in tomatoes. The initial symptoms of the disease are water-soaked, small dark brown spots surrounded by a yellow halo on tomato leaves. Since the pathogen is seed-borne, control of the disease is difficult.
