Turnip mosaic virus (TuMV) is a Potyvirus of the family Potyviridae that causes diseases in cruciferous plants, among others. The virus is usually spread by 40-50 species of aphids in a non-persistent manner. Infected plants, especially the natural hosts, show symptoms such as chlorotic local lesions, mosaic, mottling, puckering or rugosity. TuMV is a positive-sense single stranded RNA virus, consisting of a non-enveloped, helical capsid that is filamentous and flexuous, with an average length of 720 nm. The TuMV genome is linear and monopartite (single particle). The virus has a thermal inactivation point (TIP) of 62 °C, and longevity in vitro (LIV) of 3–4 days.
Application of nb tu a gene in regulating plant resistance to turnip mosaic virus and method for cultivating transgenic plant
This invention discloses the application of the NbTuA gene in *Nicotiana benthamiana* in regulating plant resistance to turnip mosaic virus (CMV) and a method for cultivating transgenic plants. The NbTuA gene sequence is shown in SEQ ID NO:1. This invention involves cloning the NbTuA gene from *Nicotiana benthamiana* and constructing a vector fused with a YFP tag. Genetic transformation is then performed using Agrobacterium-mediated T-DNA transformation to construct transgenic plants of *Nicotiana benthamiana*. The *Nicotiana benthamiana* NbTuA transgenic plants obtained by this invention can significantly inhibit CMV infection.
