Abstract
Cymbidium mosaic virus (CymMV) is one of economically important viruses that cause significant losses of orchids in the world. In the present study, a reverse transcription recombinase polymerase amplification (RT-RPA) assay combined with a lateral flow immunostrip (LFI) assay was developed for the detection of CymMV in orchid plants. A pair of primers containing fluorescent probes at each terminus that amplifies highly specifically a part of the coat protein gene of CymMV was determined for RT-RPA assay. The RT-RPA assay involved incubation at an isothermal temperature (39°C) and could be performed rapidly within 30 min. In addition, no cross-reactivity was observed to occur with odontoglossum ringspot virus and cymbidium chlorotic mosaic virus. The RT-RPA with LFI assay (RT-RPA-LFI) for CymMV showed 100 times more sensitivity than conventional reverse transcription polymerase chain reaction (RT-PCR). Furthermore, the RT-PCR-LFI assay demonstrated the simplicity and the rapidity of CymMV detection since the assay did not require any equipment, by comparing results with those of conventional RT-PCR. On-site application of the RT-RPA-LFI assay was validated for the detection of CymMV in field-collected orchids, indicating a simple, rapid, sensitive, and reliable method for detecting CymMV in orchids.

Abstract
In the last decades, the evolution of molecular diagnosis methods has generated different advanced tools, like loop-mediated isothermal amplification (LAMP). Currently, it is a well-established technique, applied in different fields, such as the medicine, agriculture, and food industries, owing to its simplicity, specificity, rapidity, and low-cost efforts. LAMP is a nucleic acid amplification under isothermal conditions, which is highly compatible with point-of-care (POC) analysis and has the potential to improve the diagnosis in plant protection. The great advantages of LAMP have led to several upgrades in order to implement the technique. In this review, the authors provide an overview reporting in detail the different LAMP steps, focusing on designing and main characteristics of the primer set, different methods of result visualization, evolution and different application fields, reporting in detail LAMP application in plant virology, and the main advantages of the use of this technique.

Abstract
Cymbidium mosaic virus (CymMV) and Odontoglossum ringspot virus (ORSV) are the two most prevalent viruses infecting orchids and causing economic losses worldwide. Mixed infection of CymMV and ORSV could induce intensified symptoms as early at 10 days post-inoculation in inoculated Phalaenopsis amabilis, where CymMV pathogenesis was unilaterally enhanced by ORSV. To reveal the antiviral RNA silencing activity in orchids, we characterized the viral small-interfering RNAs (vsiRNAs) from CymMV and ORSV singly or synergistically infecting P. amabilis. We also temporally classified the inoculated leaf-tip tissues and noninoculated adjacent tissues as late and early stages of infection, respectively. Regardless of early or late stage with single or double infection, CymMV and ORSV vsiRNAs were predominant in 21- and 22-nt sizes, with excess positive polarity and under-represented 5'-guanine. While CymMV vsiRNAs mainly derived from RNA-dependent RNA polymerase-coding regions, ORSV vsiRNAs encompassed the coat protein gene and 3'-untranslated region, with a specific hotspot residing in the 3'-terminal pseudoknot. With double infection, CymMV vsiRNAs increased more than 5-fold in number with increasing virus titres. Most vsiRNA features remained unchanged with double inoculation, but additional ORSV vsiRNA hotspot peaks were prominent. The potential vsiRNA-mediated regulation of the novel targets in double-infected tissues thereby provides a different view of CymMV and ORSV synergism. Hence, temporally profiled vsiRNAs from taxonomically distinct CymMV and ORSV illustrate active antiviral RNA silencing in their natural host, Phalaenopsis, during both early and late stages of infection. Our findings provide insights into offence-defence interactions among CymMV, ORSV and orchids.

Abstract
Milk vetch dwarf virus (MDV) is a member of the genus Nanovirus, and its genome is composed of multiple circular 1-kb ssDNA components. In this study, we first determined that the diseased tobacco samples obtained in Zhucheng, Shandong Province were naturally infected with MDV using a polymerase chain reaction (PCR) assay. Subsequently, loop-mediated isothermal amplification (LAMP) was developed for the detection of MDV for the first time. The Mg2+ and dNTP concentrations and the reaction temperature and time of the LAMP were optimized to 8 mM, 1.8 mM, 65 °C, and 60 min, respectively. The best ratio of the inner primers (FIP and BIP) to the outer primers (F3 and B3) was 2:1. The LAMP detection limit was 100 times greater than that of PCR. The nucleotide amplification could be clearly observed by adding SYBR Green I. The positive and negative reactions exhibit distinctly different colors in daylight; however, the positive reactions exhibit green fluorescence under a UV lamp. Therefore, the method is stable, sensitive and specific.

Abstract
A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the detection of Apple chlorotic leaf spot virus (ACLSV) and Apple stem pitting virus (ASPV), two important viruses frequently occurring in pear trees. A set of four RT-LAMP primers designed based on the highly conserved region of each CP gene of the two viruses showed high specificity and feasibility for ACLSV and ASPV detections. The RT-LAMP assays for ACLSV and ASPV in pear samples were 104 and 103 times more sensitive than that of conventional RT-PCR assays. The RT-LAMP under optimal reaction condition was subsequently utilized in the detection of the two viruses in-vitro cultures of pear and field pear samples. This study provides a rapid and sensitive tool to determine the infection statues of the two viruses in pear certification program.

Abstract
Lily mottle virus (LMoV; genus Potyvirus, family Potyviridae) infects plants of the genus Lilium, causing a reduction in flower and bulb quality. A rapid and sensitive loop-mediated isothermal amplification (LAMP) assay was developed to detect the coat protein gene of LMoV. This LAMP method was highly specific for LMoV, with no cross-reaction with other lily viruses. The sensitivity of LMoV using the LAMP assay was 100 times more sensitive than that using conventional polymerase chain reaction. A reverse transcription LAMP (RT-LAMP) was then successfully applied to detect LMoV RNA. The newly established LAMP and one-step RT-LAMP provide an alternative method for detecting LMoV in lily plants.

Abstract
Chilli veinal mottle virus (ChiVMV) causes significant economic loss to chilli cultivation in northeastern India, as well as in eastern Asia. In this study, we have developed a single-tube one-step reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay for rapid, sensitive and specific diagnosis of ChiVMV. Amplification could be visualized after adding SYBR Green I (1000×) dye within 60 min under isothermal conditions at 63 °C, with a set of four primers designed based on the large nuclear inclusion protein (NIb) domain of ChiVMV (isolate KC-ML1). The RT-LAMP method was 100 times more sensitive than one-step reverse transcription polymerase chain reaction (RT-PCR), with a detection limit of 0.0001 ng of total RNA per reaction.

Abstract
A system for simultaneous detection of two orchid-infecting viruses was developed and applied to several orchid species. The detection system involved multiplex reverse transcription-polymerase chain reaction (RT-PCR) and could simultaneously identify Cymbidium mosaic virus (CymMV) and Odontoglossum ringspot virus (ORSV) from the orchid species studied. Multiplex RT-PCR was conducted using two virus-specific primer pairs and an internal control pair of primers to amplify the CymMV and ORSV coat protein regions, and orchid 18S rDNA, respectively. For optimization of multiplex RT-PCR conditions, serial dilutions of total RNA and cDNA were performed and the detection limit of the system was evaluated. The optimized multiplex detection system for CymMV and ORSV was applied to various orchid species, including several cultivars of Doritaenopsis, Cymbidium, Dendrobium, and Phalaenopsis to test the efficacy of this method. Our results indicate that the multiplex RT-PCR detection system will be a rapid, simple, and precise diagnosis tool in a range of orchid species.

Abstract
Grass carp reovirus (GCRV) has been assigned to a newly established Aquareovirus genus in the family of Reoviridae which leads to haemorrhagic disease and extremely high mortality rate in grass carp. In this study, comparison was made between the novel one-step reverse transcription loop-mediated isothermal amplification (RT-LAMP) and the reverse transcription polymerase chain reaction (RT-PCR) for detection of grass carp reovirus. The result indicated that RT-LAMP had × 10 higher sensitivity comparable to RT-PCR. The specificity of the two methods for GCRV detection were both developed successfully by other three aquatic viruses. In the field trial, both RT-PCR and RT-LAMP methods were applied to detect the samples from different infected organs and tissues. The result demonstrated that RT-LAMP had a high accuracy to confirm the diagnosis as well as the RT-PCR. This study showed that the RT-LAMP, compared to the RT-PCR, was simple, time-saving, convenient, but required specificity primers and possibly generated false positive product. Its products, unlike RT-PCR, could not be direcly used in further molecular research after purification. Thus RT-LAMP might be an optimal diagnostic method for rapid and preliminary diagnosis of GCRV infection in resource-limited setting situation.

Abstract
In this study, loop-mediated isothermal amplification (LAMP) and real-time LAMP assays were developed to detect the dioxin-degrading bacterium Ochrobactrum anthropi strain BD-1 in soil. Four primers were designed to use ITS gene amplification for the strain O. anthropi BD-1. The real-time LAMP assay was found to accomplish the reaction by 1 pg of genomic DNA load when used for nucleic acid amplification. This assay was then applied to detect O. anthropi BD-1 in eight soil samples collected from a dioxin-contaminated site. The results demonstrated that these newly developed LAMP and real-time LAMP assays will not only be useful and efficient tools for detecting the target gene, but also be used as molecular tools for monitoring the growth of dioxin-degrading O. anthropi in the soil. This is the first report to demonstrate the use of LAMP assays to monitor the presence of O. anthropi in dioxin-contaminated soil. The application of this method should improve the biomonitoring of dioxin contamination.

Abstract
A collection of 147 Potato virus Y (PVY) isolates from tomato, originating from several commercial fields and greenhouses in different regions of Poland, was tested for the presence of PVY by reverse-transcription polymerase chain reaction. However, in some cases, the results obtained were ambiguous. Therefore, a sensitive reverse-transcription loop-mediated isothermal amplification method was developed for rapid detection of PVY isolates. Phylogenetic and recombination analyses were performed based on sequences of the coat protein gene. In comparison with results obtained in 2008, the presence of other strains besides PVY(N)Wi-P was confirmed. A novel recombinant between PVY(NTN) and PVY(N)Wi-P strains was detected. Our results indicate an increasing distribution and variability of the PVY population on tomato in Poland.

Abstract
A betaine-free reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed and optimised for detecting tomato chlorosis virus (ToCV), one of the most important viruses that infect tomato crops worldwide. A set of four specific primers was designed against the RNA-dependent RNA polymerase (RdRp) gene. The betaine-free RT-LAMP procedure could be completed within 40 min under isothermal conditions at 60 °C without a thermal cycler, and no cross-reactivity was seen with other tomato viral pathogens. Sensitivity analysis showed that RT-LAMP could detect viral dilutions up to 2.0×10(-7)ng, which is 100-times more sensitive than reverse transcription-polymerase chain reaction (RT-PCR). In addition, naked-eye observation after staining in-tube RT-LAMP products with SYBR Green I facilitated detection of ToCV by avoiding the requirement for ethidium staining following gel electrophoresis. These results suggest that ToCV RT-LAMP is a rapid, sensitive, and affordable diagnostic tool that is more suitable than RT-PCR for the detection and surveillance of ToCV in field samples.

Abstract
Orchid plants, Phalaenopsis and Dendrobium in particular, are commercially valuable ornamental plants sold worldwide. Unfortunately, orchid plants are highly susceptible to viral infection by Cymbidium mosaic virus (CymMV) and Odotoglossum ringspot virus (ORSV), posing a major threat and serious economic loss to the orchid industry worldwide. A major challenge is to generate an effective method to overcome plant viral infection. With the development of optimized orchid transformation biotechnological techniques and the establishment of concepts of pathogen-derived resistance (PDR), the generation of plants resistant to viral infection has been achieved. The PDR concept involves introducing genes that is(are) derived from the virus into the host plant to induce RNA- or protein-mediated resistance. We here review the fundamental mechanism of the PDR concept, and illustrate its application in protecting against viral infection of orchid plants.

Abstract
A multiplex reverse transcription polymerase chain reaction (RT-PCR) assay was developed for simultaneous detection of three orchid viruses: cymbidium mosaic virus (CymMV), odontoglossum ringspot virus (ORSV), and orchid fleck virus (OFV). Primers were used to amplify nucleocapsid protein gene fragments of 845 bp (ORSV), 505 bp (CymMV) and 160 bp (OFV). A 60-bp amplicon of plant glyceraldehyde-3-phophate dehydrogenase mRNA was included as an internal control against false negatives. The assay was validated against 31 collected plants from six orchid genera and compared with results obtained by transmission electron microscopy (TEM). The RT-PCR assay proved more sensitive than TEM for detection of OFV.

Abstract
Papaya ringspot virus (PRSV) and Papaya leaf distortion mosaic virus (PLDMV), which causes disease symptoms similar to PRSV, threaten commercial production of both non-transgenic-papaya and PRSV-resistant transgenic papaya in China. A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay to detect PLDMV was developed previously. In this study, the development of another RT-LAMP assay to distinguish among transgenic, PRSV-infected and PLDMV-infected papaya by detection of PRSV is reported. A set of four RT-LAMP primers was designed based on the highly conserved region of the P3 gene of PRSV. The RT-LAMP method was specific and sensitive in detecting PRSV, with a detection limit of 1.15×10(-6)μg of total RNA per reaction. Indeed, the reaction was 10 times more sensitive than one-step RT-PCR. Field application of the RT-LAMP assay demonstrated that samples positive for PRSV were detected only in non-transgenic papaya, whereas samples positive for PLDMV were detected only in commercialized PRSV-resistant transgenic papaya. This suggests that PRSV remains the major limiting factor for non-transgenic-papaya production, and the emergence of PLDMV threatens the commercial transgenic cultivar in China. However, this study, combined with the earlier development of an RT-LAMP assay for PLDMV, will provide a rapid, sensitive and cost-effective diagnostic power to distinguish virus infections in papaya.

Abstract
Papaya leaf distortion mosaic virus (PLDMV) can infect transgenic papaya resistant to a related pathogen, Papaya ringspot virus (PRSV), posing a substantial threat to papaya production in China. Current detection methods, however, are unable to be used for rapid detection in the field. Here, a reverse-transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the detection of PLDMV, using a set of four RT-LAMP primers designed based on the conserved sequence of PLDMV CP. The RT-LAMP method detected specifically PLDMV and was highly sensitive, with a detection limit of 1.32×10(-6) μg of total RNA per reaction. Indeed, the reaction was 10 times more sensitive than one-step RT-PCR, while also requiring significantly less time and equipment. The effectiveness of RT-LAMP and one-step RT-PCR in detecting the virus were compared using 90 field samples of non-transgenic papaya and 90 field samples of commercialized PRSV-resistant transgenic papaya from Hainan Island. None of the non-transgenic papaya tested positive for PLDMV using either method. In contrast, 19 of the commercialized PRSV-resistant transgenic papaya samples tested positive by RT-LAMP assay, and 6 of those tested negative by RT-PCR. Therefore, the PLDMV-specific RT-LAMP is a simple, rapid, sensitive, and cost-effective tool in the field diagnosis and control of PLDMV.

Abstract
A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the detection of Cucurbit chlorotic yellows virus (CCYV). In this procedure, a set of four primers matching a total of six sequences in the coat protein gene region of CCYV was synthesized for the RT-LAMP assay using total RNA extracted from CCYV-infected melon leaf tissues, and the optimum reaction temperature and assay time were determined. The sensitivity assay showed that the virus was detectable in RT-LAMP reactions at dilutions of 1×10(-11), which was 10(5) times more sensitive than the RT-PCR assay. The RT-LAMP assay for CCYV and Sweet potato chlorotic stunt virus (SPCSV) exhibited high specificity for CCYV. This simple and sensitive method has potential for detection of CCYV in samples collected in the field.

Abstract
Cucumber green mottle mosaic virus (CGMMV) has caused serious damage to Cucurbitaceae crops worldwide. The virus is considered one of the most serious Cucurbitaceae quarantine causes in many countries. In this study, a highly efficient and practical one-step reverse transcription loop-mediated isothermal amplification (RT-LAMP) was developed for the detection of CGMMV. The total RNA or crude RNA extracted from watermelon plants or seeds could be detected easily by this RT-LAMP assay. The RT-LAMP assay was conducted in isothermal (63°C) conditions within 1h. The amplified products of CGMMV could be detected as ladder-like bands using agarose gel electrophoresis or visualized in-tube under UV light with the addition of a fluorescent dye. The RT-LAMP amplification was specific to CGMMV, as no cross-reaction was observed with other viruses. The RT-LAMP assay was 100-fold more sensitive than that of reverse-transcription polymerase chain reaction (RT-PCR). This is the first report of the application of the RT-LAMP assay to detect CGMMV. The sensitive, specific and rapid RT-LAMP assay developed in this study can be applied widely in laboratories, the field and quarantine surveillance of CGMMV.

Abstract
The most common virus affecting potatoes in the field worldwide is Potato Leafroll virus (PLRV), belonging to the family Luteoviridae, genius Plerovirus. There are several molecular methods to detect PLRV including polymerase chain reaction (PCR), Multiplex AmpliDet RNA and double antibody sandwich ELISA (DAS-ELISA). But these techniques take a long time for 3h to two days, requiring sophisticated tools. The aim of this study was to reduce the time required to detect PLRV, using a newly designed loop-mediated isothermal amplification (LAMP) technique requiring only an ordinary water bath or thermoblock. PLRV RNA was extracted from overall 80 infected naturally potato leaves. A set of six novel primers for the LAMP reaction was designed according to the highly conserved sequence of the viral coat protein (CP) gene. LAMP was carried out under isothermal conditions, applying the Bst DNA polymerase enzyme; the LAMP products were detected visually using the GeneFinder™ florescence dye. A positive result using the GeneFinder™ dye was a color change from the original orange to green. Results confirmed LAMP with GeneFinder™ provides a rapid and safe assay for detection of PLRV. Since with other molecular methods, equipping laboratories with a thermocycler or expensive detector systems is unavoidable, this assay was found to be a simple, cost-effective molecular method that has the potential to replace other diagnostic methods in primary laboratories without the need for expensive equipment or specialized techniques. It can also be considered as a reliable alternative viral detection system in further investigations.

Abstract
Tobacco viruses may cause a wide range of diseases that heavily reduce tobacco quality and yield worldwide. In order to detect viral diseases in tobacco fields, a one-step reverse transcription loop-mediated isothermal amplification (RT-LAMP) method was established. Nucleotide amplification could be observed clearly after adding SYBR Green I, within 60 min under isothermal conditions, at 63-65 °C with a set of primers targeting the viral coat protein (CP) genes of tobacco viruses including cucumber mosaic virus (CMV), potato virus Y (PVY), tobacco etch virus (TEV), tobacco mosaic virus (TMV) and tobacco vein banding mosaic virus (TVBMV). This method has high specificity and sensitivity. The sensitivity of the RT-LAMP was 10 to 100 times higher than that of the conventional RT-PCR method. The RT-LAMP assay was proven reliable for virus diagnosis of tobacco samples from the field.
