PLASTOCYANIN TRANSIT PEPTIDE INTERACTS WITH POTATO VIRUS X COAT PROTEIN, WHILE SILENCING OF PLASTOCYANIN REDUCES COAT PROTEIN ACCUMULATION IN CHLOROPLASTS AND SYMPTOM SEVERITY IN HOST PLANTS

Plastocyanin Transit Peptide Interacts with Potato virus X Coat Protein, While Silencing of Plastocyanin Reduces Coat Protein Accumulation in Chloroplasts and Symptom Severity in Host Plants

Potato virus X coat protein (PVXCP) is, through communication with host proteins, involved in processes such as virus movement and symptom development.Here, we report that PVXCP also interacts with the precursor of plastocyanin, a protein involved in photosynthesis, both in vitro and in vivo.Yeast two-hybrid analysis indicated that PVXCP interacted
