Abstract:

【Objective】 In this study, the LAMP (loop-mediated isothermal amplification) was used to detect TAV (Tomato aspermy virus). 【Method】 Using TAV CP cDNA clones as templates, the reaction conditions (such as Mg2+, dNTPs, betaine and primers concentrations) optimized and the sensitivities of LAMP and RT-PCR were compared in detecting TAV. 【Result】 The LAMP method was developed in this experiment and it was more sensitive than RT-PCR method for detecting TAV. 【Conclusion】 The LAMP as a simple and quick method can accurately detect TAV in chrysanthemum samples.
