“…Although it led to several disease outbreaks in potato in different parts of the world in the past, through implementation molecular detection and eradication programs its presence in potato has now been significantly diminished in North America and Europe. By contrast, PSTVd is still prevalent in Central-Asia (CIP, unpublished) and China (Qiu et al 2016). Although PSTVd presence in potato has declined recently globally, the opposite is the case for tomato where outbreaks have been increasing due to its worldwide spread in tomato seed via the international seed trade (Constable et al 2019).…”

Viruses are among the most significant biotic constraints in potato production. In the century since the discovery of the first potato viruses we have learned more and more about these pathogens, and this has accelerated over the last decade with the advent of high-throughput sequencing in the study of plant virology. Most reviews of potato viruses have focused on temperate potato production systems of Europe and North America. However, potato production is rapidly expanding in tropical and subtropical agro-ecologies of the world in Asia and Africa, which present a unique set of problems for the crop and affect the way viruses can be managed. In this chapter we review the latest discoveries in potato virology as well as the changes in virus populations that have occurred over the last 50 years, with a particular focus on countries in the (sub-)tropics. We also review the different management approaches including use of resistance, seed systems, and cultural approaches that have been employed in different countries and reflect on what can be learnt from past research on potato viruses, and what can be expected in the future facing climate change.

“…Potato (Solanum tuberosum L.) plays an important role for sustainable world food security and it is among the four largest crop produced annually at high proportion of the global total area and yield after rice, wheat and disease PTNRD which is a most prevalent disease induced by PVY, probably caused by emerging of the biological and genetic diversity of PVY leading to increased viral incidence in seed production (Karasev et al 2013). Very recently, molecular characterization of potato spindle tuber viroid (PSTVd) isolates from potato has been done to reveal the viroid variants (Qiu et al 2016). Epidemiologically, the main viruses that are causing mosaics in potato plants are PVY, PVA, and PVM and sometimes by PVX, and these diseases can be caused by one of the viruses or by coinfection of both of them (Kostiw 2011).…”

Major In Vitro Techniques for Potato Virus Elimination and Post Eradication Detection Methods. A Review

2019

Potato is an economically important agro-industrial crop that is conventionally propagated, however; its potential transmission of viruses through seed tubers from generation to generation is a major limitation of potato yield production. In order to produce potato virus-free and sufficient amount of potato seed tubers, several approaches of in vitro methods for virus elimination have been developed. Meristem culture has been used alone or combined with techniques such as thermotherapy, electrotherapy, cryotherapy and chemotherapy as the best alternative method for treating potato infected by viruses. Recent literature has shown that to eliminate potato virus significantly depends upon the potato cultivar, antiviral agents, type of virus, the duration of heat treatment. Appropriate duration for efficiency elimination is still under investigation. Viral elimination rate can be detected through serological methods such as enzyme-linked immunosorbent assay (ELISA) and molecular biology technique such as real time reverse transcriptase polymerase chain reaction (real time RT-PCR) that are used for pre and post elimination virus detection to evaluate the efficiency and the accuracy of virus elimination method. The purpose of this review is to highlight virus elimination methods in potato and recommending the most effective tool for virus detection in order to ensure the production of potato plantlet free of viruses. Resumen La papa es un cultivo de importancia económica agro-industrial que se propaga de manera convencional, no obstante, la potencial transmisión de virus a través del tubérculo-semilla de generación en generación es una limitación mayor en la producción del rendimiento. Con el fin de producir papa libre de virus y suficiente cantidad de tubérculo-semilla de papa, se han desarrollado varias estrategias de métodos in vitro para la eliminación de los virus. El cultivo de meristemos se ha usado solo o combinado con técnicas tales como termoterapia, electroterapia, crioterapia y quimioterapia, como el mejor método alternativo para tratar papa infectada por virus. La literatura reciente ha demostrado que para eliminar virus significativamente se depende de la variedad de papa, agentes antivirales, tipo de virus, la duración del tratamiento térmico. Aun esta bajo investigación la duración apropiada para la eliminación eficiente. El nivel de la eliminación del virus puede detectarse por métodos serológicos, tales como el inmunoensayo con enzimas conjugadas (ELISA) y técnica de biología molecular, como la reverso-transcripción de reacción en cadena de la polimerasa en tiempo real (RT-PCR) que se usan para la detección del virus pre y post eliminación para evaluar la eficiencia y la precisión del método de eliminación del virus. El propósito de esta revisión es resaltar los métodos de eliminación de virus en papa y en la recomendación de la herramienta más efectiva para la detección de virus para asegurar la producción de plántulas de papa libres de virus.

“…PSTVd primarily infects solanaceous plants leading to dwar sm, leaf chlorosis and curling, and malformation of leaves and fruit [13]. PSTVd can also infect some ornamental plants and has been reported in several Asian and Middle Eastern countries including Japan [1,4,7,9,12,14,17]. In addition, several other pospiviroids have been reported such as tomato chlorotic dwarf viroid (TCDVd) that causes chlorotic leaves, severe dwar sm and bunching in tomatoes and coleus blumei viroid (CbVd)-5 from coleus [6, 8, 9, 18].…”

Dahlias naturally infected with potato spindle tuber viroid (PSTVd) do not exhibit symptoms. Therefore, if highly pathogenic isolates infect dahlias, there is significant risk of PSTVd infecting other plants via dahlia. In this study, almost all highly pathogenic isolates can infect dahlia plants, but symptoms vary depending on the cultivar. When mixed inocula composed of dahlia isolates and highly pathogenic isolates were tested, the dahlia isolates dominantly infected dahlia plants; however, the highly pathogenic isolates also co-infected plants. In addition, our results indicate that seed or pollen transmission from infected dahlia plants does not occur.
