Arbuscular Mycorrhizal Fungi in Biotic and Abiotic Stress Conditions: Function and Management in Horticulture
(Elsevier, 2022) Demir, S.; Danesh, Y.R.; Boyno, G.; Najafi, S.
Rhizosphere can be defined as the dynamic microcosm between the plant, microorganisms, and soil components in a narrow region where the habitats of plant roots are formed. Mycorrhizal fungi, particularly arbuscular mycorrhizal fungi, are known to promote plant development, increase plant nutrient absorption, promote plant resilience to biotic and abiotic stress conditions, and improve soil structure, and members of the rhizosphere’s mutual microsymbiosis. As the ecological function of mycorrhizal symbiosis has become much better understood in recent years, this biodiversity and its evolution is no longer considered a black box but a source of extensive networking and molecular communication in the rhizosphere. In this review, it has been tried to describe the effect and mechanism of action of arbuscular mycorrhizae against environmental and cultural stress factors in horticultural production systems. © 2022 Elsevier Inc.

Effect of Microwave Radiation on the Germination and Growth Characteristics of Maize (Zea Mays)
(Scibulcom Ltd., 2017) Danesh, Y.R.; Ghiyasi, M.; Najafi, S.; Amirnia, R.
In order to study the effect of microwave radiation on germination and growth characteristics of maize (Zea mays), an experiment was carried out in the year 2010 in seed physiology laboratory at the Department of Agriculture, Urmia University in a factorial experiment with completely randomised blocks design with four replicates. The first factor was three different powers (100, 200 and 300 Ws) and the second factor was five different times (0, 30, 60, 90 and 120 s). The results showed the significant differences among interaction between power and time treatments on germination, radicle and stem length, fresh and dry weight, germination rate as well as time of reaching 50% germination (T50) at the probability level of 1%. The highest rate of germination, radicle and stem length was observed in the treatment of 200 Ws power with duration of 90 s. The least rate of germination, radicle and stem length as well as dry weight was found at the treatment of 300 Ws power with maximum time duration. © 2017, Scibulcom Ltd. All rights reserved.
Nanoparticles From Microbes: the Next Generation Tool for Combatting Plant Diseases
(CRC Press, 2024) Boyno, G.; Teniz, N.; Durak, E.D.; Danesh, Y.R.; Demir, S.
Microbe-synthesized NanoParticles (MNPs) show great potential for controlling plant diseases, offering advantages over chemical pesticides. MNPs possess unique physical and chemical properties, leading to higher efficacy, lower toxicity, and environmental safety. They can be produced using cost-effective and eco-friendly methods, making them a viable alternative. MNPs exhibit diverse mechanisms of action, including antifungal, antibacterial, and antiviral activities. They can penetrate pathogen cell walls, disrupting their normal processes and causing death or reduced virulence. Additionally, MNPs can activate plant defence mechanisms, enhancing resistance to infections. This chapter provides an overview of MNPs’ applications in plant disease management, exploring microorganisms involved in nanoparticle synthesis and the underlying mechanisms. MNPs offer advantages like cost-effectiveness, environmental friendliness, and specificity in synthesis. However, challenges remain, such as understanding long-term environmental and human health effects, regulatory and economic barriers, and developing efficient delivery systems. Despite these challenges, MNPs have the potential to transform agriculture and promote sustainable practices. Further research is needed to address limitations and overcome barriers. MNPs could become a versatile, environmentally friendly alternative in various fields. With continued progress, they offer a promising solution for plant disease control, fostering sustainable and effective approaches. © 2025 Irshad Mahmood, Rizwan Ali Ansari and Rose Rizvi.
Rock Phosphate Solubilizing Potential of Soil Microorganisms: Advances in Sustainable Crop Production
(Multidisciplinary Digital Publishing Institute (MDPI), 2023) Khoshru, B.; Nosratabad, A.F.; Mitra, D.; Chaithra, M.; Danesh, Y.R.; Boyno, G.; Sinha, S.
Phosphorus (P) is one of the most important elements required for crop production. The ideal soil pH for its absorption by plants is about 6.5, but in alkaline and acidic soils, most of the consumed P forms an insoluble complex with calcium, iron, and aluminum elements and its availability for absorption by the plant decreases. The supply of P needed by plants is mainly achieved through chemical fertilizers; however, in addition to the high price of these fertilizers, in the long run, their destructive effects will affect the soil and the environment. The use of cheap and abundant resources such as rock phosphate (RP) can be an alternative strategy for P chemical fertilizers, but the solubilization of P of this source has been a challenge for agricultural researchers. For this, physical and chemical treatments have been used, but the solution that has recently attracted the attention of the researchers is to use the potential of rhizobacteria to solubilize RP and supply P to plants by this method. These microorganisms, via. mechanisms such as proton secretion, organic and mineral acid production, siderophore production, etc., lead to the solubilization of RP, and by releasing its P, they improve the quantitative and qualitative performance of agricultural products. In this review, addressing the potential of rhizosphere microbes (with a focus on rhizobacteria) as an eco-friendly strategy for RP solubilization, along with physical and chemical solutions, has been attempted. © 2023 by the authors.
