ORIGINAL_ARTICLE The genus Diaporthe Fuckel consists of a large number of species recorded as pathogens, saprobes, and endophytes. While more than 1200 species of Diaporthe have been recorded to date, only pathogenic strains of Diaporthe were reported from Japan, notably affecting economically important plants. This study successfully elucidated the diversity of endophytic Diaporthe spp. from Prunus sensu lato (s.l.), commonly known as the Sakura tree, along with the addition of two novel species of Diaporthe to the Japanese mycobiota. In this study, a polyphasic approach was employed, using multi-locus analysis of 5 loci, including internal transcribed spacer (ITS) region, partial sequence of translation elongation factor 1–alpha (TEF), beta-tubulin (TUB), histone H3 (HIS) and calmodulin (CAL) genes. Additionally, morphological observation was also conducted by inducing sporulation of the isolates in artificial media. As a result, two novel species were introduced: Diaporthe endoprunicola A.H. Ujat & Y. Hattori and Diaporthe pseudoamygdali A.H. Ujat & Y. Hattori, along with confirmation of previously documented Diaporthe species in Prunus s.l. https://plantfungalres.az/uploads/2024-1/1.pdf 2024-06-14 https://doi.org/10.30546/2664-5297.2024.7.1.2 Diaporthaceae multi-locus phylogeny new taxa taxonomy systematics Anysia Hedy Ujat 1 AUTHOR Yukako Hattori 2 AUTHOR Hayato Masuya 3 AUTHOR Abd Hadi Kamil Farhana Fatin 4 AUTHOR Chiharu Nakashima 5 AUTHOR

ORIGINAL_ARTICLE Many species belonging to the Lamiaceae family are commonly used in traditional Lebanese cuisine and medicine. The essential oils (EOs) obtained from these plants are rich in active compounds with potential applications in various fields including the food sector. Their strong ability to protect foods from pathogenic and decaying microorganisms has been documented. In this context, the effectiveness of EOs obtained from Lavandula angustifolia Mill., Satureja thymbra L. and Thymbra capitata (L.) Cav. (syn. Coridothymus capitatus Rchb.f.) collected in Lebanon was evaluated against eight bacteria (Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa, Proteus mirabilis, Listeria monocytogenes, Staphylococcus aureus, Bacillus cereus and Enterococcus faecalis) and two yeasts (Candida albicans and C. parapsilosis) by in vitro test. S. thymbra showed the highest antibacterial activity followed by T. capitata and L. angustifolia. P. aeruginosa proved to be the most resistant microorganism. All three EOs were able to completely inhibit the C. albicans and C. parapsilosis growth. S. thymbra was further tested in vivo against S. aureus used to experimentally contaminate chicken breast samples where EO managed to significantly counteract its growth up to 72 (bacterial suspension at 3 log CFU/g) and 48 hours (bacterial suspension at 8 log CFU/g). https://plantfungalres.az/uploads/2024-1/2.pdf 2024-06-14 https://doi.org/10.30546/2664-5297.2024.7.1.25 antifungal activity aromatic plants biopreservation CFU food pathogens secondary metabolites Lisa Vallone 1 AUTHOR Marc El Beyrouthy 2 AUTHOR Sara Vitalini 3 AUTHOR Marcello Iriti 4 AUTHOR

ORIGINAL_ARTICLE This investigation presents ecological characteristics of Betula medwediewii Regel, a relict woody species and Veratrum album L., an important medicinal plant, both naturally distributed in Western Transcaucasia. Elemental analyses in plants and soils was carried out and soil-plant relationships in the leaves evaluated. The findings obtained from leaves of B. medwediewii revealed that nitrogen, phosphorus, potassium, calcium, iron and copper concentrations were within the limit values in contrast to those of, magnesium and nickle, which were higher. It was also seen that in the lower cauline leaves of V. album, the nitrogen, phosphorus, potassium, calcium, magnesium and copper showed normal values while iron and nickle concentrations exceeded the normal levels. In general, the concentrations of all elements investigated in the soil samples of both species were low. https://plantfungalres.az/uploads/2024-1/3.pdf 2024-06-14 https://doi.org/10.30546/2664-5297.2024.7.1.33 Conservation ecology plant-soil interactions Medwediew's birch relict white hellebore Munir Ozturk 1 AUTHOR Volkan Altay 2 AUTHOR Alvina Gul 3 AUTHOR Ernaz Altundag 4 AUTHOR Mahir Kucuk 5 AUTHOR

ORIGINAL_ARTICLE Cryphonectria parasitica, the causal agent of chestnut blight, was officially found in Azerbaijan in 2004. Currently, the disease is widespread and causes severe damage in seven out of eight forest districts where sweet chestnut (Castanea sativa) is native. Studies conducted in 2015 and 2023 showed that the local fungal population is dominated by a single vegetative compatibility type which is also widespread in neighboring Georgia. All 296 sampled and analyzed bark cankers were caused by hypovirus-free C. parasitica strains suggesting that the hypovirulenceinducing virus CHV1 is still not present in Azerbaijan. Here we discuss the possibility of artificially introducing this virus into Azerbaijani C. parasitica populations by treating virulent cankers with CHV1-infected fungal strains. https://plantfungalres.az/uploads/2024-1/5.pdf 2024-06-14 https://doi.org/10.30546/2664-5297.2024.7.1.45 biological control Cryphonectria parasitica disease incidence hypovirulence mycovirus Dilzara N.

ORIGINAL_ARTICLE The genus Ferula L. (Apiaceae) has 130 species, widespread in the Caucasus, Central Asia, Siberia, China (Xinjiang), Afghanistan, Iran and North Africa. There are eight species of this genus in the Republic of Azerbaijan. The main part of the chemical substances of the plants of genus Ferula species are sesquiterpene coumarins, lactones, alcohol esters and essential oils. For the first time, a crystalline substance with the composition C24H32O5 with a melting point of 157-159°C was isolated from an ethanol extract of Ferula persica roots collected in the phase of full ripening of seeds using column chromatography. Based on spectral (UV)-ultraviolet, (IR)-infrared, (NMR)-nuclear magnetic resonance PMR and 13C NMR, DEPT and two-dimensional experimental methods COSY, HSQC, HMBC and physical indicators (polarometry, melting point) data, it has been proven that this substance has a structure identical to mogoltavidin. To determine the configuration of a substance in the PMR spectrum, were used which is a classical method the chemical shift and the value of the spin-spin interaction constant. The purpose of the current study was to identify the coumarin content of F. persica roots. Obtained results in the future can be assessed for identifying chemotoxonomic position of the species within the genus. https://plantfungalres.az/uploads/2024-1/6.pdf 2024-06-14 https://doi.org/10.30546/2664-5297.2024.7.1.51 chemical shift sesquiterpen lactone spinspin interaction constant Woodward-Fieser rules UV IR NMR configuration Elvin H.

ORIGINAL_ARTICLE One way to preserve the purity of ecosystems is the use of polyene antibiotics (PA) with specificity and selectivity of their action on viral and fungi plant cells. In the process of our prolonged scientific activity on the base of polyene antibiotics was discovered a new membrane-active preparation whose basic action is connected with its ability to quickly, high selectivity, and efficiency to destroy simultaneously viral and fungi infections of plants. The most effective of the studied PA were amphotericin B and levorin A2, produced respectively by soil microorganisms Actinomyces nodosus and Actinomyces levoris. A theoretical analysis of practical aspects of the use of PA is presented to develop an ecological model of environmental protection from carriers of infection. The relationship between the structure of antibiotics and their function inmembranes has been established. The physicochemical properties and biological role of dimethyl sulfoxide (DMSO) in combination with PA were studied for the first time. It was found that the use of amphotericin B and levorin A2 in the DMSO complex enhances the biological activity of the initial antibiotics. It was found that the studied antibiotics have a steep dependence of conductivity on their concentration, which made it possible to identify the effective concentrations of each of them in the formation of ion channels. The conducted research allowed to theoretically substantiate and present practical recommendations for the targeted synthesis of PA and their derivatives with specified properties. For example, alkylation of the polar part of PA molecules increases the biological activity and selectivity of their action on cell membranes. As a result of the conducted research, for the first time it was possible to identify a new compound Infanvir, which has the ability to effectively and selectively suppress the growth of pathogenic viral infections in plant cells. A Eurasian patent has been obtained for the developed drug. https://plantfungalres.az/uploads/2024-1/7.pdf 2024-06-14 https://doi.org/10.30546/2664-5297.2024.7.1.61 crops fungi infection INFANVIR polyene antibiotics viral infection Gulnar H.
