Rahmani H. R., Mohammadi Goltapeh E. & Safaie N. 2015. The role  of  endophytic fungus Pirifomospora indica  in  plant  disease  management. Plant Pathology Science 5(1):48-61.

Piriformospora indica as the one of the most important soil endophytic microorganism, can increase yield of plants per unit area, by modifying the physiological characteristics of the host plants. It also provide the possibility of crop production in saline and arid soils or even in some conditions with biotic and abiotic stresses.  It grants resistance to plant against diseases, through the induction of systemic resistance. Also the fungus can cause an increase in resistance to salinity and drought, through the increase in antioxidant capacity of root cells and levels of resistance proteins in their host plants. In order to adopt organic farming and achieve sustainable agriculture, this fungus can be used as a suitable alternative for chemical fertilizers and pesticides.

Rahmani  H. R. &  Mohamadi-Goltapeh E. 2016. Six forest species of truffles. Plant Pathology Science 5(2):1-12.

Edible mushrooms that are known as the truffle are classified in apothecial ascomycetes. They are obligate ectomycorrhiza of plants and produce their fruiting bodies on or below the surface of the soil. The genus Tuber belongs to the order Pezizales, class Pezizomycets, and has numbers of species with universal distribution. So far, France, Italy, United Kingdom and New Zealand have tried for the commercial production of truffle. Among the species of edible truffle of the universe, two valuable species, the white truffle, T. magnatum, and the black truffle, T. melanosporum, are the most valuable species. Because of their economic and medicinal importance, this is necessary to perform scientific research for their accurate identification.

Mohammadi AH, Haghdel M, Mirabolfathy M, Alaei H (2022) Armillaria root and crown rot disease in pistachio orchards. Plant Pathology Science 11(2):92-102. 
Doi: 10.2982/PPS.11.2.92  

Pistachio is one of the most important horticultural products in Iran which its production is always affected by biotic and abiotic limiting factors. Armillaria crown and root rot caused by Armillaria mellea, is an important disease in pistachio orchards, which causes the death of fertile trees. Control of the disease is difficult, costly and rarely successful. Symptoms of the disease in shoots of affected trees includes yellowing, early defoliation, sudden wilting, dieback of branches and reduction shoot growth. These symptoms, together with the decay and browning of woody tissues and the formation of white to creamy mycelial sheets in the roots and crown, as well as the observation of rhizomorphs of the fungus, are sufficient evidence for definitive diagnosis of Armillaria crown and root rot in pistachio trees. The infection process begins with the growth of hyphae or rhizomorphs and their firm attachment to the surface of the roots. The pathogen uses a combination of methods such as mechanical pressure, toxin production, and cell wall-degrading enzymes to penetrate the root tissues. Successful control of the disease is possible only by combining chemical, cultural, biological control methods and use of resistant rootstocks and cultivars due to delay in diagnosis of the disease before the spread of the pathogen in plant and soil and the appearance of symptoms, the presence of an extensive network of rhizomorphs at a distance from the tree and deep in the soil and formation of the mycelium beneath the plant bark or inside dead wood.
