Abstract
Abadkhah M. and Koolivand D. 2018. The biosensors and their application in plant pathology. Plant Pathology Science 7(2):47-59. DOI:10.2982/PPS.7.2.47
 
 Preventing plant disease damage requires the use of new, powerful, simple and portable tools to quickly diagnose pathogens. Today, biosensor technology  known as a powerful tool for evaluating conventional methods in agricultural sciences. Sensitivity, selectivity and portability of biosensors made it possible to develop them as special tools for rapid analysis of compounds in samples with low concentration. Biosensors have three main components, biological element, transducer and readout system. The most important application of biosensors in plant pathology is rapid detection of plant pathogens, in order to reduce the use of expensive and environmentally-damaging chemicals. This article introduces different types of biosensors and their applications in plant pathology.

Abstract
Esmaeilzadeh, F., & Koolivand, D. (2022). Tomato brown rogue fruit virus. Plant Pathology Science 12(1), 84-93.    
 
Tomato brown rugose fruit virus (ToBRFV) is an emerging pathogen that generally causes disease in greenhouses. This virus causes yellow areas, malformation and brown necrotic lesions on tomato fruits. This virus, which has a global distribution, has recently been reported using molecular methods in the greenhouses of few provinces of Iran. According to the report of this virus from Iran, the characteristics of the ToBRFV, its symptoms, host range, mode of transmission and spread, and its management methods have been described based on previous studies.

The application of biopolymers in the management of plants viral diseases

Abstract
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.
