Tomato Bushy Stunt Virus Spread Is Regulated by Two Nested Genes That Function in Cell-to-Cell Movement and Host-Dependent Systemic Invasion

Purification of Tomato Bushy Stunt Virus by Differential Centrifugation

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...

A newly identified role for Tomato bushy stunt virus P19 in short distance spread.

SUMMARY This study identified a role for the Tomato bushy stunt virus (TBSV) p19 protein (P19) in local lesion expansion on cowpea (Vigna unguiculata), and cell-to-cell movement in pepper (Capsicum annuum). The contribution to short distance spread in both hosts was strongly influenced by a cluster of charged amino acids between positions 72 and 78 on the 172 amino acid P19. Charged amino acids...

Physicochemical Studies on Tomato Bushy Stunt Virus Variants

Tomato bushy stunt virus particles have previously been physically and chemically well characterized. Different strains, however, are known to have different host plants and symptoms, and they can be distinguished serologically. In an attempt to correlate this behavior with physicochemical properties, we have performed a comparative study on isolates of four of the main variants of this virus (...

Tomato bushy stunt virus (TBSV) infecting Lycopersicon esculentum.

Tomato bushy stunt virus (TBSV) was detected in tomato crop (Lycopersicon esculentum) in Egypt with characteristic mosaic leaf deformation, stunting, and bushy growth symptoms. TBSV infection was confirmed serologically by ELISA and calculated incidence was 25.5%. Basic physicochemical properties of a purified TBSV Egh isolate were identical to known properties of tombusviruses of isometric 30-...
