摘要: 为了明确蔬菜病毒种类,探索快速、灵敏、低成本、高通量的病毒检测方法。将10种蔬菜病毒,烟草花叶病毒(Tobacco mosaic virus,TMV)、黄瓜花叶病毒(Cucumber mosaic virus,CMV)、黄瓜绿斑驳花叶病毒(Cucumber green mottle mosaic virus,CGMMV)、番茄花叶病毒(Tomato mosaic virus,ToMV)、蚕豆萎蔫病毒(Broad bean wilt virus,BBWV)、芜菁花叶病毒(Turnip mosaic virus,TuMV)、小西葫芦黄花叶病毒(Zucchini yellow mosaic virus,ZYMV)、番茄褪绿病毒(Tomato chlorosis virus,ToCV)、马铃薯Y病毒(Potato virus Y,PVY)和番茄环纹斑点病毒(Tomato zonate spot virus,TZSV)的cp基因质粒DNA顺次固定在同一张硝酸纤维素膜(NC膜)上,根据10种蔬菜病毒的cp基因序列制备地高辛(DIG)标记的特异性探针,利用dot-Southern blot方法一次性检测10种病毒。再采用dot-Southern blot、dot-Northern blot、PCR和ELISA方法检测TMV,比较不同检测方法的灵敏度。结果发现,dot-Southern blot方法可在同一张NC膜上一次性检出10种病毒的cp基因质粒DNA。dot-Southern blot检测TMV cp基因质粒DNA和cp基因cDNA的最低浓度分别为5×10-2 ng·μL-1和5×10-1 ng·μL-1,dot-Northern blot检测感染TMV蔬菜样本总RNA的最低浓度为5×10-2 ng·μL-1,PCR检测TMV cp基因质粒DNA的最低浓度为5×10-3 ng·μL-1,RT-PCR检测TMV cDNA的最低浓度为5×10-2 ng·μL-1,dot-ELISA和TAS-ELISA检测感染TMV蔬菜病汁液的最低浓度为9.8 ng·μL-1和78 ng·μL-1。说明dot-Southern blot能够一次性检出多种病毒,可用于蔬菜病毒复合侵染检测。dot-Southern blot、dot-Northern blot、RT-PCR和PCR等核酸检测方法的灵敏度相对较高,而ELISA检测方法的灵敏度相对较低。

Abstract:

To clarify the species of vegetable viruses, this study was designed to explore rapid, sensitive, low-cost and high-throughput virus detection methods. The plasmid DNA of cp genes of ten vegetable viruses containing Tobacco mosaic virus (TMV), Cucumber mosaic virus(CMV), Cucumber green mottle mosaic virus (CGMMV), Tomato mosaic virus (ToMV), Broad bean wilt virus(BBWV), Turnip mosaic virus(TuMV), Zucchini yellow mosaic virus(ZYMV), Tomato chlorosis virus(ToCV), Potato virus Y(PVY) and Tomato zonate spot virus(TZSV) were fixed on a same nitrocellulose membrane(NC membrane) in order. The DIG-labeled specific probes based on the sequences of the cp genes of these ten vegetable viruses were separately prepared, and these ten viruses could be simultaneously detected by dot-Southern blot. Thereafter, TMV was detected by dot-Southern blot, dot-Northern blot, PCR, and ELISA methods to compare the sensitivities of the diverse methods. The results revealed that the plasmid DNA of cp genes of ten vegetable viruses could be detected on the same NC membrane by dot-Southern simultaneously. The minimum detectable concentration (MDC) of plasmid DNA and the cDNA of TMV-cp gene by dot-Southern was 5 ×10-2 ng·μL-1 and 5×10-1 ng·μL-1 respectively. The MDC of the total RNA extracted from TMV-infected vegetable by dot-Northern blot was 5×10-2 ng·μL-1. The MDC of TMV plasmid DNA by PCR and TMV cDNA RT-PCR approaches was 5×10-3 ng·μL-1 and 5×10-2 ng·μL-1 respectively. The MDC of extracted diseased saps from TMV-infected vegetable samples by dot-ELISA and TAS-ELISA assays was 9.8 ng·μL-1 and 78 ng·μL-1, respectively. The results indicated that the various viruses could be detected by dot-Southern blot in this experiment at a time, which should be adaptable to detect the mixed infection of diverse vegetable viruses. The nucleic acid detection methods such as dot-Southern blot, dot-Northern blot, RT-PCR and PCR have higher sensitivity, but the sensitivity of the ELISA detection method is relatively low.
