“…Plant defense responses to colonization by pathogenic fungi usually involve the induction of enzymes that can degrade the fungal cell wall, as well as pathogenesis-related (PR) proteins and proteins involved in plant cell wall modification [ 57 , 58 ]. Although two PR proteins were found by proteomics to be more expressed in mycorrhizal roots of O. maculata , transcriptomic data indicated that plant defense responses were lower in mycorrhizal roots than in non-mycorrhizal roots.…”

Orchids form endomycorrhizal associations with fungi mainly belonging to basidiomycetes. The molecular events taking place in orchid mycorrhiza are poorly understood, although the cellular changes necessary to accommodate the fungus and to control nutrient exchanges imply a modulation of gene expression. Here, we used proteomics and transcriptomics to identify changes in the steady-state levels of proteins and transcripts in the roots of the green terrestrial orchid Oeceoclades maculata. When mycorrhizal and non-mycorrhizal roots from the same individuals were compared, 94 proteins showed differential accumulation using the label-free protein quantitation approach, 86 using isobaric tagging and 60 using 2D-differential electrophoresis. After de novo assembly of transcriptomic data, 11,179 plant transcripts were found to be differentially expressed, and 2175 were successfully annotated. The annotated plant transcripts allowed the identification of up- and down-regulated metabolic pathways. Overall, proteomics and transcriptomics revealed, in mycorrhizal roots, increased levels of transcription factors and nutrient transporters, as well as ethylene-related proteins. The expression pattern of proteins and transcripts involved in plant defense responses suggested that plant defense was reduced in O. maculata mycorrhizal roots sampled in nature. These results expand our current knowledge towards a better understanding of the orchid mycorrhizal symbiosis in adult plants under natural conditions.

The object of research: morphological and cultural characteristics of micromycetes: yeast Saccharomyces cerevisiae and mycelial fungi Mucorracemosus grown on agar medium.The subject of research: flax seed suspension, ultrafine powder of double oxide of divalent and trivalent ferrum, micromycetes: yeast Saccharomyces cerevisiae and mycelial fungi MucorracemosusInvestigated problem: ensuring the bacteriostatic properties of raw materials and obtaining products with an extended dates of expiry.The subject in scientific results: the impact of nanoparticles (NP FeO×Fe2O3) on the bacteriostatic (protective) properties of flax seeds against fungal infections has been studied and the dependence of bacteriostatic properties on the amount of nanomagnetite has been determined. The ability of nanomagnetite to improve the bacteriostatic properties of flax seeds has been proven: addition of 0.1 %; 0.15 %; 0.2 % of nanomagnetite suppresses the development of microflora (micromycetes) in flax seed samples by 8–20 times. A reduction in the number of micromycetes (yeast Saccharomycescerevisiae and mycelial fungi Mucorracemosus) by 8–10 times and the size by 10–20 times was established compared to the control. The rational content of nanoparticles (NPs FeO×Fe2O3–nanomagnetite) has been determined as 0.15 % of the weight of the recipe mixture. The proposed mathematical model makes it possible to predict the effectiveness of using NP FeO×Fe2O3 – nanomagnetite to inhibit the growth of mycelial fungi to ensure the bacteriostatic properties of raw materials, in particular, flax seeds. The area of practical use of the research results: food industry enterprises specializing in the production of bakery and flour confectionery products using a mixture of wheat and rye flour with the addition of food additives. Innovative technological product: flour raw material with a mineral nano-additive suspension based on the double oxide of divalent and trivalent ferrum, which allows to ensure quality and extend dates of expiry of the product. Scope of the innovative technological product: to enhance the quality of food supply of the troops in extreme conditions

“…Endophytic fungi can degrade the plant cell wall and change its structure by secreting cell wall degradative enzymes (CWDEs) such as cellulase, laccase, pectinase, and xylanase, thereby infiltrating, colonizing and proliferating tissues in plant [ 22 ]. The findings of Fourier transform infrared spectroscopy (FTIR) detection demonstrated that pathogens had a similar reaction to the plant cell wall.…”

“…The findings of Fourier transform infrared spectroscopy (FTIR) detection demonstrated that pathogens had a similar reaction to the plant cell wall. However, most endophytes do not break down lignin and carbohydrates, resulting in nonpathogenic and asymptomatic responses to infected hosts [ 22 ]. Additionally, under the same conditions, endophytes have a stronger ability to infect the host than do pathogens [ 23 ].…”

Endophytic fungi infect plant tissues by evading the immune response, potentially stimulating stress-tolerant plant growth. The plant selectively allows microbial colonization to carve endophyte structures through phenotypic genes and metabolic signals. Correspondingly, fungi develop various adaptations through symbiotic signal transduction to thrive in mycorrhiza. Over the past decade, the regulatory mechanism of plant-endophyte interaction has been uncovered. Currently, great progress has been made on plant endosphere, especially in endophytic fungi. Here, we systematically summarize the current understanding of endophytic fungi colonization, molecular recognition signal pathways, and immune evasion mechanisms to clarify the transboundary communication that allows endophytic fungi colonization and homeostatic phytobiome. In this work, we focus on immune signaling and recognition mechanisms, summarizing current research progress in plant-endophyte communication that converge to improve our understanding of endophytic fungi.
