Mutations in the HC-Pro gene of zucchini yellow mosaic potyvirus: effects on aphid transmission and binding to purified virions.

The Journal of general virology - 1 Apr 1998

Peng Y H, Kadoury D, Gal-On A, Huet H, Wang Y, Raccah B

Abstract excerpt

Transmission of zucchini yellow mosaic virus (ZYMV) by aphids was examined by introducing mutations within the highly conserved proline-threonine-lysine (PTK) motif of the helper component proteinase (HC-Pro) using a cDNA full-length clone. Replacement of proline by alanine (ATK) in the PTK motif abolished transmission almost completely both from plants and from membranes. Substitution of the basic lysine by...
