Rastgou M. 2018. Characteristics of Ourmia melon virus (OuMV). Plant Pathology Science 7(2): 34-46. DOI :10.2982/PPS.7.2.34

Ourmia melon virus (OuMV) is one of the viruses that cause mosaic disease in melon (Cucumis melo L.), in West-Azerbaijan Province and some other parts of Iran including Guilan, Fars and Alborz Provinces. This virus was first detected in diseased cucurbits with mosaic and ring spot symptoms, in Urmia in 1978. The virus has unique characteristics that differentiate it from other viruses that infect cucurbits. The virus particles are bacilliform with conical ends. Genome consists of three linear positive-sense single-stranded RNAs, each encoding one protein. Host range mostly limited to Cucurbitaceae and Solanaceae families. Ourmia melon virus, Epirus cherry virus and Cassava virus C are three species those are placed in the genus Ourmiavirus.

Pouraziz, P., & Koolivand, D. (2024). The application of biopolymers in the management of plants viral diseases. Plant Pathology Science, 13(1),125-134.
Polymers with natural origin are known as biopolymers. Due to their biocompatibility and biodegradable properties, biopolymers have a wide range of applications in various fields such as agriculture, medicine, and industry. Biopolymers limit the activities of plant pathogens by increasing the immune system of plants by influencing resistance genes and also activating resistance mechanisms. Therefore, the use of these substances to combat plant pathogens has found a wide application in agriculture. The use of biopolymers to deal with plant pathogens such as fungi and bacteria is a suitable solution to reduce their damage. Also, treatment of the virus-infected plant with biopolymers reduces the symptoms and damage of the disease. The molecular antiviral mechanisms of some biopolymers such as chitosan, chitin, oligochitosan, β-glucans, lentine, alginate, hydrogel and their compounds in the management of plants viral diseases are described in this article.

Abstract

An important part of the floriculture industry, which has a high ornamental value and has become an essential part of people's daily lives, are cut flowers. The Netherlands, Colombia and the United States are the major producers of cut flowers, and more than 80% of the production of these flowers in Iran is concentrated in Tehran, Fars, Ilam and Khuzestan provinces, respectively. Alstroemeria, an important ornamental plant, is used both as a cut flower and for pot cultivation. Its flower production is rapidly increasing in Europe and other parts of the world, and due to its long vase life, high yield and productivity, and wide color variety, it has become one of the most commercially successful ornamental cut flowers in the United States, Britain, the Netherlands, and Japan. The area under cultivation and production of alstroemeria in Iran in 2023 were 42 hectares and approximately 45 million branches, respectively, and Tehran province had the highest area under cultivation and production. This plant is cultivated in Iran through rhizomes and mostly in greenhouse conditions. Alstroemeria has been reported to be infected with diseases such as root rot, wilt and viral diseases. Virus infection of alstroemeria is a serious concern because this plant mainly reproduces vegetatively. Among plant diseases, viral diseases are the most important problem for alstroemeria and can significantly reduce the quality and quantity of the plant and limit global trade. So far, 24 alstroemeria-infecting viruses have been reported in the world.
