Application of seaweeds in plant disease management
Ali Asghar Dehghan, Reza Ghaderi,
Volume 9, Issue 1 (3-2020)
Abstract
Dehghan AA, Ghaderi R (2020) Application of seaweeds in plant diseases management. Plant Pathology Science 9(1):101-107.         DOI: 10.2982/PPS.9.1.101.
Algae are the most important plant growth stimulants due to their high content of minerals, amino acids, vitamins and growth regulators such as auxin, cytokinin and gibberellin. Use of these stimuli in crops can improve rooting, yield, photosynthetic capacity and their resistance to pathogens. Application of algae (mainly seaweeds) against various plant diseases including bacterial, fungal, viral and nematode diseases as well as pests has been proven. Seaweeds are used as a powder or extract mixed with soil, or foliar spray to control of plant diseases. They are usually involved in controlling plant pathogens by inducing plant resistance, antagonistic activity by induced activity of other microorganisms, and enhancing plant growth. In general, seaweeds can be applied as biofertilizers, biostimulators and soil amendments in integrated plant diseases management programs.

Situation of Fusarium root and crown rot disease of wheat in Iran

Volume 10, Issue 1 ((Autumn & Winter) 2021)
Abstract
Dehghanpour Farashah S, Salehzadeh M (2021) Situation of Fusarium root and crown rot  disease of wheat in Iran. Plant Pathology Science 10(1):97-106. Doi: 10.2982/PPS.10.1.97.
 
Fusarium root and crown rot is one of the most important wheat diseases in the world, which causes a significant reduction in yield. The disease is also common in many wheat production areas in Iran. F. acuminatum, F. avenaceum, F. culmorum, F. solani, F. semitectum, F. equiseti, F. crookwellense, F. lateritium, F. moniliforme, F. oxysporum, F. pseudograminearum, F. sambucinum, F. subglutinans,F. proliferatum, F. longipes, F. nygamai, F. compactum, F. diversisporum, F. fujikuroi, F. javanicum, F. flocciferum and F. tricinctum have been reported from rotten tissues of wheat root and crown in Iran and F. culmorum and F. pseudograminearum are known as the most important disease agents. Disease management methods including crop rotation, removal of diseased plant debris, setting planting date, biological control, seed disinfection with protective fungicides and cultivation of relatively resistant cultivars are described in this article.

 
Defense responses by nitric oxide in plant-pathogen interaction
Saeedeh Dehghanpour Farashah,
Volume 12, Issue 2 ((Spring and Summer) 2023)
Abstract
Dehghanpour Farashah S (2023) Defense responses by nitric oxide in plant-pathogen interaction. Plant Pathology Science 12(2):130-142.
The control of diseases in agriculture often relies on pesticides and chemical fertilizers, which negatively affect the rhizosphere natural microflora and ecosystem balance. Today, researchers are looking to replace these chemicals with other environment friendly agents to improve agricultural production and control plant pathogens. Research on the interaction of nitric oxide (NO) with plant pathogens has shown that NO is a key messenger in the response of plants to biotic and abiotic stresses. Due to the role of NO in the regulation of plant defense genes, especially through programmed cell death, it has attracted the attention of many plant pathologists. Although NO plays an important role in the hypersensitive reaction in response to various biotic and abiotic stresses, it has been found that NO also plays a role in regulating the expression of genes related to non-specific resistance. In this review, the role of nitric oxide in plant-pathogens interaction has been investigated.
