Rapid diagnosis of Ralstonia solanacearum infection sweet potato in China by loop-mediated isothermal amplification. Arch Microbiol 2020; 203:777-785. [PMID: 33052451 DOI: 10.1007/s00203-020-02059-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2019] [Revised: 09/07/2020] [Accepted: 09/24/2020] [Indexed: 10/23/2022]
Abstract
Bacterial wilt of sweet potato is caused by Ralstonia solanacearum, which is distributed in southern China and causes significant economic losses each year. The pathogen is soil- and rhizome-borne, and thus its rapid detection may prevent the occurrence and spread of the disease. R. solanacearum has been listed as a quarantine disease in China. With the advent of molecular biology, many novel tools have been explored for the rapid identification of plant pathogens. In this study, a strain-specific detection method was developed for this specific pathogen that infects sweet potato using loop-mediated isothermal amplification (LAMP). A set of new LAMP-specific primers was designed from the orf428 gene, which can specifically detect the R. solanacearum bacterium that infect sweet potato. The LAMP reaction consisted of 8.0 mmol·L-1Mg2+, 1.4 mmol·L-1 dNTPs, and 0.32U μL-1 Bst 2.0 DNA polymerase and was performed at 65 °C for 1 h. The amplification products were detected by visualizing a mixture of color changes using SYBR Green I dye and assessing ladder-like bands by electrophoresis. Our method has specificity, i.e., it only detected R. solanacearum in sweet potato, and it has high sensitivity, with a detection limit of 100 fg·μL-1 genomic DNA and 103 CFU·mL-1 of bacterial fluid. In addition, R. solanacearum could be directly detected in infected sweet potato tissues without the need for DNA extraction. The LAMP method established in this study is a highly specific, sensitive, and rapid tool for the detection of bacterial wilt in sweet potato caused by R. solanacearum.

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
Rice blast is one of the most serious diseases for rice, and controlling the filamentous fungus Magnaporthe oryzae that causes rice blast is crucial for global food security. Typically, early infected rice does not show symptoms. Therefore, the early diagnosis of rice blast is particularly important to avoid uncontrollable propagation of rice blast fungus. In the present work, a rapid and efficient loop-mediated isothermal amplification (LAMP) method was developed to detect the pathogen at the early infected stage of rice. The Alb1 superfamily hypothetical protein MGG_04322, a nuclear shuttling factor involved in ribosome and melanin biogenesis, was chosen as the target for designing the LAMP primers. The LAMP assay enabled rapid detection of as little as 10 pg of pure genomic DNA of M. oryzae. In addition, we established the quantitative LAMP (q-LAMP) detection system to quantify the conidia of rice blast fungus. The q-LAMP assay enabled rapid detection (within 35 min) of the fungal spores at a sensitivity of 3.2 spores/ml. In addition, the assay sets up the linearization formula of the standard curve as y = 0.3066 + 15.33x (where x = amplification of time), inferring that spore number = 100.60y. In addition, the q-LAMP assay was successfully used to detect the presence of the virulence strains of M. oryzae (wild type) in comparison with that of the two mutant strains by quantifying the biomass within host tissue. These results provide a useful and convenient tool for detecting M. oryzae that could be applied in the incubation period of rice blast before symptoms appear.

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
Loop‐mediated isothermal amplification (LAMP) amplifies DNA with high specificity, efficiency and rapidity under isothermal conditions by using a DNA polymerase with high displacement strand activity and a set of specifically designed primers to amplify targeted DNA strands. Following its first discovery by Notomi et al. (2000Nucleic Acids Res 28: E63), LAMP was further developed over the years which involved the combination of this technique with other molecular approaches, such as reverse transcription and multiplex amplification for the detection of infectious diseases caused by micro‐organisms in humans, livestock and plants. In this review, available types of LAMP techniques will be discussed together with their applications in detection of various micro‐organisms. Up to date, there are varieties of LAMP detection methods available including colorimetric and fluorescent detection, real‐time monitoring using turbidity metre and detection using lateral flow device which will also be highlighted in this review. Apart from that, commercialization of LAMP technique had also been reported such as lyophilized form of LAMP reagents kit and LAMP primer sets for detection of pathogenic micro‐organisms. On top of that, advantages and limitations of this molecular detection method are also described together with its future potential as a diagnostic method for infectious disease.

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.
