“…Moreover, in our study of marigold, several bacterial endophytes demonstrated antagonistic activity against the plant pathogenic fungi F. oxysporum , F. solani , and R. solani . Higher proportions of endophytes with antifungal properties were previously reported among plant-associated bacteria with Hypericum perforatum [62] , [63] and Chelidonium majus L. [64] . Evidence is available that biologically active compounds of medicinal plants may affect endophytic microbes living inside the plant tissue and their physiological functions [24] , [65] , [66] .…”

<abstract> Endophytes colonizing plant tissue play an essential role in plant growth, development, stress tolerance and plant protection from soil-borne diseases. In this study, we report the diversity of cultivable endophytic bacteria associated with marigold (<italic>Calendula officinalis</italic> L.) by using 16S rRNA gene analysis and their plant beneficial properties. A total of 42 bacterial isolates were obtained from plant tissues of marigold. They belonged to the genera <italic>Pantoea, Enterobacter, Pseudomonas, Achromobacter, Xanthomonas, Rathayibacter, Agrobacterium, Pseudoxanthomonas</italic>, and <italic>Beijerinckia</italic>. Among the bacterial strains, <italic>P. kilonensis</italic> FRT12, and <italic>P. rhizosphaerae</italic> FST5 showed moderate or vigorous inhibition against three tested plant pathogenic fungi, <italic>F. culmorum, F. solani</italic> and <italic>R. solani</italic>. They also demonstrated the capability to produce hydrolytic enzymes and indole-3-acetic acid (IAA). Five out of 16 isolates significantly stimulated shoot and root growth of marigold in a pot experiment. The present study reveals that more than half of the bacterial isolates associated with marigold (<italic>C. officinalis</italic> L.) provided antifungal activity against one or more plant pathogenic fungi. Our findings suggest that medicinal plants with antimicrobial activity could be a source for selecting microbes with antagonistic activity against fungal plant pathogens or with plant growth stimulating potential. These isolates might be considered as promising candidates for the improvement of plant health. </abstract>

“…TSB medium resulted in significantly lower plant height and lower fresh biomass weight compared to H 2 0 when both treatments were tested in the absence of the fungus. Other studies did not show a phytotoxic effect of TSB medium to pecan and peach plants, lettuce seeds as well to seeds and shoots of tomatoes 10,30,31,48,49 . However, these prior studies did not have guargum added to the liquid medium.…”

The fungus, Sclerotinia sclerotiorum, causes white mold disease and infects a broad spectrum of host plants (> 500), including soybean with yield losses of up to 70%. Biological control is a potential alternative for management of this severe plant pathogen, and relative to chemical fungicides, provides broad benefits to the environment, farmers and consumers. The symbiotic bacteria of entomopathogenic nematodes, Xenorhabdus spp. and Photorhabdus spp., are characterized by the production of antimicrobial compounds, which could serve as potential sources for new bio-fungicides. The objectives of this study were to assess cell-free supernatants (CFS) of 16 strains of these bacteria cultures on S. sclerotiorum mycelium growth; assess the volatiles of X. szentirmaii cultures on the fungus mycelium and sclerotium inhibition; and evaluate the X. szentirmaii cultures as well as their CFS on the protection of soybean seeds against the white mold disease. Among the 16 strains, the CFS of X. szentirmaii showed the highest fungicidal effect on growth of S. sclerotiorum. The CFS of X. szentirmaii inhibited > 98% of fungus growth from mycelium and sclerotia, whereas the volatiles generated by the bacterium culture inhibited to 100% of fungus growth and 100% of sclerotia production. The bacterial culture diluted to 33% in water and coated on soybean seeds inhibited S. sclerotiorum and protected soybean plants, allowing 78.3% of seed germination and 56.6% of plant development. Our findings indicate potential for a safe and novel control method for S. sclerotiorum in soybean. Moreover, this is the first study to indicate that volatile organic compounds from Xenorhabdus spp. can be used in plant disease suppression.

“…In traditional medicine of Uzbekistan, around 20% of herbal plants are used for treating various ailments (Mamedov et al 2004: Shurigin et al 2018; Egamberdieva and Jabborova 2018). The plant species described in Avicenna's book, such as Malva silvestris L., Cannabis sativa L., Ferula assafoetida L., Sesamum indicum L., Pyrus malus L., Punica granatum L., and Trachyspermum ammi L. are used till today to treat various illnesses (Buranova 2015).…”

In traditional medicine of Uzbekistan, around 20% of herbal plants are used to treat various ailments, including diseases caused by pathogenic bacteria and fungi. Though conventional medicinal plants are common in Uzbekistan, many plant species potentially useful for new pharmaceuticals are less studied. They contain various biological compounds with antibacterial and antifungal activities, that could be developed into drugs. The search for novel antimicrobial compounds, especially against multidrug-resistant pathogens from aromatic and herbal plants is an essential scientific research line. However, the antimicrobial properties of several medicinally important plants from various countries are still unknown. This review aims to provide an up-to-date report on the antimicrobial activity of medicinal plants endemic to Uzbekistan widely used in traditional medicine.
