The invention provides a kind of method that Fast synchronization detects rice stripe virus (RSV) and rice black-streaked dwarf virus (RBSDV) in insect amboceptor small brown rice planthopper body, platymiscium protection field.Three primers are designed: [A] RS-F, [B] RB-F, [C] RSRB-R, wherein A/C combine detection rice stripe virus, B/C combine detection rice black-streaked dwarf virus according to rice stripe virus RNA4 and rice black-streaked dwarf virus S2 nucleotide sequence.After single head small brown rice planthopper extracts total serum IgE, only need the RT-PCR of a reaction, can detect rice stripe virus and rice black-streaked dwarf virus two-strain, the Fast synchronization achieving two-strain in small brown rice planthopper body detects.Relative to the method for a traditional a kind of virus of RT-PCR reaction detection, greatly having saved cost, saved the time, is a kind of quick, easy, sensitive, special detection method.Present method can be applicable to the monitoring of field small brown rice planthopper colony with malicious rate, also can be applicable to the correlative study work of virus and amboceptor Coupling effects.
Description
Technical field
The present invention relates to a kind of method that rice stripe virus in amboceptor insect small brown rice planthopper body and rice black-streaked dwarf virus Fast synchronization are detected, platymiscium protection field.
Background technology
Rice stripe virus (Ricestripevirus, RSV) be the prototypical member of very thin Tobamovirus (Tenuivirus), its stripe disease caused is one of important disease of paddy rice, between many decades in the past, this disease based on the vast rice district outbreak of epidemic of East China Dao Qu, forms great threat to Rice Production in China.Such as, within 2004, Jiangsu Province's onset area reaches 2,355 ten thousand mu, account for 79% of Jiangsu Monitoring of Paddy Rice Plant Area, paddy rice total crop failure in blocks, within 2005, reach 2,800 ten thousand mu, and start to Zhejiang, Anhui, Henan, Shandong, the periphery provinces and cities such as Shanghai spread, be once called as " cancer " on paddy rice because of its serious hazardness, causing very large social repercussion.
Rice black-streaked dwarf virus (Riceblack-streakeddwarfvirus, RBSDV), be a kind ofly on paddy rice endanger serious virus disease, be under the jurisdiction of Phytoreovirus section Fijivirus and belong to (Fijivirus), virion is spherical, symptom main manifestations in early stage in field is that plant stunts, leaf dark green, there is wax drop-wise projection in the later stage, then form secret note on blade, leaf sheath and cane, very large to the yield effect of paddy rice, grave illness field even can cause without output.Except paddy rice, this virus also can infect corn and cause maize rough dwarf virus, infects wheat and cause the green short disease of wheat, in addition, also can infect multiple gramineous weeds.Within 1963 and 1966, black streaked dwarf virus of rice is with popular in Jiangsu Province, China, Shanghai, Zhejiang one, and the nineties, in the many corns of China and paddy rice producing region outbreak of epidemic, causes heavy losses.This disease spreads generation in area, Jiangsu and Zhejiang Provinces in recent years, and in day by day serious trend, 2008 are only Jiangsu Province's onset area just reaches 4,000,000 mu, causes local Rice Production loss serious.
RSV and RBSDV propagates primarily of their common amboceptor insect small brown rice planthopper LaodelphaxstriatellusFall é n, and difference is that RSV can by small brown rice planthopper transovarian transmission, and RBSDV not transovarian transmission.The classical symptom of stripe disease is the striped spot or the patch that occur chlorisis, and normally, and the symptom of black streak dwarf is plant to plant height stunts, and leaf dark green, later stage visible white wax drop-wise projection, then forms secret note.Two kinds of diseases very easily distinguish diagnosis in field, but the band of amboceptor small brown rice planthopper poison situation then cannot directly be differentiated, could need realize by biology techniques.The prediction of field small brown rice planthopper colony with malicious rate has vital role with continuing to monitor in the innoxious Synthetical prevention of Rice Virus disease, can play positive directive function to the employing of follow-up Control Technology.
At present, the authentication method of the plant virus in insect amboceptor mainly contains: biological inoculation experiment, Serologic detection, electron microscopic observation and molecular Biological Detection.Biological inoculation experiment collects small brown rice planthopper thorn to inhale susceptible rice varieties, and then observe paddy rice symptom, not only workload is large, and length consuming time, and the aobvious disease time of such as black streak dwarf often needs 1 month.The dependency of Serologic detection antagonist is high, needs antibody with high specificity, and the monoclonal antibody of current RSV detects comparative maturity, and RBSDV antiserum(antisera) is also immature efficiently.Electron microscopic observation needs high level plant and instrument, and is not suitable for a large amount of sample detection, is generally applied to the research work of pathogenic characteristic.The molecular biological assay still based on RT-PCR technology that current application is more, also there is report to use the method for RT-PCR to detect RSV and RBSDV before, but the not yet technological method of report energy synchronous detection RSV and RBSDV, the virus that present method only needs RT-PCR can realize two kinds is differentiated, under the prerequisite ensureing reliability and sensitivity, simplify operation, provide cost savings and the time.
Summary of the invention
The present invention has filled up the blank in amboceptor small brown rice planthopper body on rice stripe virus and rice black-streaked dwarf virus Fast synchronization authentication technique, provide a kind of quick, easy, sensitive, special discrimination method, can be applicable to the monitoring of field small brown rice planthopper colony with malicious rate and the research work of virus and amboceptor Coupling effects.

7, result statistics
After raising poison, the small brown rice planthopper of survival carries out RT-PCR detection by present method, amounts to 255, through statistics, carries the small brown rice planthopper 93 of RSV, carries the small brown rice planthopper 20 of RBSDV, carry the small brown rice planthopper 14 of RSV and RBSDV, nontoxic small brown rice planthopper 128 simultaneously.This experiment also demonstrates small brown rice planthopper can carry RSV and RBSDV.
Example two: the synchronous detection of field small brown rice planthopper population with malicious situation
Spring in 2013 gathers overwinter generation small brown rice planthopper at Gaochun County, Nanjing polylith wheatland with chessboard method, amount to 2000, random selecting 150 after stored frozen, RNA is extracted according to the method for example one, RT-PCR detection is carried out with 3 primers, found that 3 small brown rice planthoppers carry RSV (detecting the band of 1114bp size), 2 small brown rice planthoppers carry RBSDV (detecting the band of 414bp size), do not have small brown rice planthopper to carry two-strain simultaneously, calculating area, Gaochun overwinter generation small brown rice planthopper in 2013 is with malicious rate to be RSV:2%, RBSDV:1.3%, for the forecast of virus disease and prevention and control provide data supporting.
Example three: the detection of the sick sample of paddy rice
With the biased sample of the paddy rice sample and infection RSV and RBSDV that infect RSV and RBSDV respectively for detected object, with healthy paddy rice sample for negative control.RNA is extracted according to the method for example one, RT-PCR detection is carried out with 3 primers, the sample of result infection RSV can detect the band of 1114bp size, the sample infecting RBSDV can detect the band of 414bp size, the biased sample infecting two-strain can detect the band of 1114bp and 414bp size simultaneously, healthy paddy rice sample does not have band to detect, and this illustrates that this detection method is equally applicable to the detection to paddy rice sample.Certainly, because the paddy rice sample infecting RSV and RBSDV is very easily distinguished in field symptom, therefore the susceptible initial stage that the detection of the sick sample of paddy rice can be used for before paddy rice shows disease is detected, be then of little use after aobvious disease.
