A newly identified role for Tomato bushy stunt virus P19 in short distance spread
Molecular Plant Pathology 4 (1), 67-72
Abstract: 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 near this region between positions 43 and 85 were required for long distance spread in pepper. These results indicate that the central domain of P19 plays a key role for its activities in TBSV movement and that additional regions on this protein contribute to virus spread in a host-specific manner.
