This standard is the first industry standard for entry-exit inspection and quarantine. Prunus necrotic ring spot virus detection method1 ScopeThis standard specifies the basic principles and methods for the detection and identification of Prunus necrotic ring spot virus. This standard applies to the detection of vegetative propagation materials, tissue culture seedlings, seeds and fruits of all incoming environments that may carry the Prunus necrotic ring spot virus. And identification.2 Principle2.1 Lithium necrotic ring spot virus scientific name, taxonomic status Scientific name. Prunusnecroticringspotvirus Abbreviation. PNRSV 2.2 Host range The virus has a wide range of hosts, and natural and experimental inoculation infects 21 families of dicots, which can infect most of the genus Prunus. Rose, hops. In the case of artificial inoculation, more than 180 plants can be infested. 2.3 Disease symptoms Symptoms of the disease vary depending on the isolate, cultivar and environmental conditions. Some isolates of the virus do not cause symptoms, only in the vaccination Infection can only be detected when plants are detected by serological methods; some isolates produce necrotic spots on young leaves in the year of system infection. And pores, but in later years, there are few symptoms on the leaves and fruits; other isolates produce necrotic reactions in the year of infection, with It is followed by chronic chlorotic mottled and necrotic, leafy ear processes, malformations, delayed fruit ripening, and spotted symptoms on the fruit. As appearing on sweet cherries From asymptomatic to severe wrinkled mosaic symptoms, chronic symptoms include chlorotic spots on the leaves, leaf twists, and delayed fruit ripening for days to weeks. The shape varies depending on the virus isolate. Asymptomatic infection on roses is common, with symptoms such as mosaic, delayed flowering, early autumn leaves, and more Many unformed flowers, infected plants are usually inactive. A chlorotic line and a ring spot are produced on the hop. 2.4 Distribution area Widely distributed in temperate regions, such as in Europe and the United States. 2.5 Mode of transmission Mechanical inoculation, pollen transmission, and seed transmission can also be carried out by artificial means such as asexual propagation of seedlings and transportation of tissue culture seedlings. spread. 2.6 granule morphology The genus Necrotic ring spot virus granules are equiaxed spheroids with diameters ranging from 23 nm to 27 nm, and some granules are quasi-equal spherical to short rod-shaped. (Axis ratio is 1.01 to 1.5); virions of some strains are obviously rod-shaped (axial ratio greater than 2.2); some rod-shaped granules reach 70 nm. Baton The presence or absence of granules and the proportion vary depending on the strain. 2.7 Viral genome Positive single-stranded RNA, 3-part genome, RNA-1 is 3.662 kb long, RNA-2 is 2.507 kb long, and RNA-3 is 1.887 kb long. 3 Instruments, equipment and reagents 3.1 Equipment Enzyme label detector, balance (1/10000g), PCR instrument, electrophoresis instrument, electrophoresis tank, UV transilluminator, isolation greenhouse, juicer, water bath Pot and so on. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1618-2017_English be delivered?Answer: Upon your order, we will start to translate SN/T 1618-2017_English as soon as possible, and keep you informed of the progress.
