Abstract
Sugarcane streak mosaic virus (SCSMV), now assigned to the genus Poacevirus of the family Potyviridae, was reported for the first time in 1932 in Louisiana and was believed to be strain F of sugarcane mosaic virus (SCMV) for more than six decades. SCMV-F was renamed SCSMV in 1998 after partial sequencing of its genome and phylogenetic investigations. Following the development of specific molecular diagnostic methods in the 2000s, SCSMV was recurrently found in sugarcane exhibiting streak mosaic symptoms in numerous Asian countries but not in the Western hemisphere or in Africa. In this review, we give an overview of the current knowledge on this disease and the progression in research on SCSMV. This includes symptoms, geographical distribution and incidence, diagnosis and genetic diversity of the virus, epidemiology, and control. Finally, we highlight future challenges, as sugarcane streak mosaic has recently been found in Africa, where this disease represents a new threat to sugarcane production.

Bano H, Khan JA. Development of reverse transcription loop-mediated isothermal amplification (RT-LAMP) for rapid detection of viruses infecting patchouli (Pogostemon cablin). Arch Microbiol 2024; 206:75. [PMID: 38261081 DOI: 10.1007/s00203-023-03798-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 12/08/2023] [Accepted: 12/15/2023] [Indexed: 01/24/2024]
Abstract
Patchouli (Pogostemon cablin), a highly valued medicinal plant, suffers significant economic losses following infection with Broad bean wilt virus 2 (BBWV-2) and Peanut stripe virus (PStV). In this study, a field-based isothermal technique called reverse transcription loop-mediated isothermal amplification (RT-LAMP) was established for an early and specific detection of BBWV-2 and PStV. The oligo primers were designed to target the coat protein genes of PStV and BBWV-2. The reaction conditions, such as temperature and time duration, were optimized to 65 °C for 60 min. The LAMP amplicons positive for PStV and BBWV-2 revealed characteristic ladder-type bands following agarose gel electrophoresis. Further, a colorimetric assay using a metal ion-based indicator (Hydroxy-naphthol blue, HNB) was conducted to visualize the amplified products with the naked eye, thus facilitating accessibility to field practices. The assay developed in this study was found to be virus specific, and was 100 times more sensitive than RT-PCR. Thus, the RT-LAMP assay established in this study is quick, reliable, and cost-effective for the accurate identification of BBWV-2 and PStV. It will facilitate the screening of patchouli planting materials. Further, it may reduce the risk of virus spread and could be helpful in phytosanitary programs.

Abstract
Sugarcane is one of the important food and bioenergy crops, cultivated all over the world except European continent. Like many other crops, sugarcane production and quality are hampered by various plant pathogens, among them viruses that infect systemically and cause severe impact to cane growth. The viruses are efficiently managed by their elimination through tissue culture combined with molecular diagnostics, which could detect virus titre often low at 10-12 g mL-1. To harmonize the virus diagnostics by molecular methods, we established a nanocatalysis-based high sensitive lateral flow immunochromatographic assay (LFIA) simultaneously to detect two major sugarcane viruses associated with mosaic disease in sugarcane. LFIA is known for poor sensitivity and stability with its signalling conjugates. However, we synthesized positively charged Cysteamine-gold nanoparticles and used them to prepare highly stable to sensitive immunoconjugates and as a colourimetric detection label. Further nanogold signal enhancement was performed on LFIA to obtain a high detection sensitivity, which is higher than the conventional immunoassays. The linear detection range of the nano-LIFA was 10-6 to 10-9 g mL-1, and with the signal enhancement, the LOD reached up to 10-12 g ml-1. This research paper provides relative merits and advancement on nano-LFIA for specific detection of sugarcane viruses in sugarcane for the first time.

Abstract
The early detection of plant pathogens is an appropriate preventive strategy for the management of crop yield and quality. For this reason, effective diagnostic techniques and tools, which are simple, specific, rapid and economic, are needed to be developed. Although several such technologies have been developed still most of them suffer one or the other limitation. Major limitations of the widely used diagnostic methods are requirement of trained staff and laboratory setup. Development of point-of-care diagnostic devices (handy portable devices) that require no specialized staff and can directly be used in fields is need of the hour. The aim of this review is to compile the information on current promising techniques that are in use for plant-pathogen diagnosis. Additionally, it focuses on the latest in-field pathogen diagnostic techniques with associated advantages and limitations.

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.
