Identification of tomato bushy stunt virus host-specific symptom determinants by expression of individual genes from a potato virus X vector.

Identification of tomato bushy stunt virus host-specific symptom determinants by expression of individual genes from a potato virus X vector.

In this study, we analyzed the influence of two nested genes (p19 and p22) of tomato bushy stunt virus (TBSV) on disease symptoms in systemically infected plants and in local lesion hosts. The contribution of individual genes was determined by bioassays with an infectious clone of wild-type TBSV, with p19/p22 mutant derivatives, and by expression of individual TBSV genes from a heterologous pot...

Purification of Tomato Bushy Stunt Virus by Differential Centrifugation

Host-specific generation and maintenance of Tomato bushy stunt virus defective interfering RNAs.

The accumulation of Tomato bushy stunt virus (TBSV) defective interfering RNAs (DIs) has been observed in several species of plants, but the involvement of host-specific processes and the functional role of DIs are still poorly understood. In this study, the accumulation of DIs was compared after several passages of TBSV through Nicotiana benthamiana and pepper (Capsicum annuum). As anticipated...

On the rigidity of RNA in tomato bushy stunt virus.

The motional state of RNA in tomato bushy stunt rirlls, both in thr crystalline st,attx and in solution, has been invrstigat,ed IuGng 31P nuclear magnetic resonance methods. It, has been found that t’hr RNA is highly immobile in tho nativ Crus. and it is suggested that t,he lack of a high-resolution X-ray diffraction patt,crn for either the RNB or the N-terminal repions of the pro&n coat molcrn...
