Abstract
An isolate of potato virus Y (PVY), PVY-H14, was collected on the island of Oahu, Hawaii, from tomato plants exhibiting stunting and necrotic lesions on leaves. PVY-H14 triggered the hypersensitive resistance response in potato cultivars King Edward and Maris Bard, typical of a PVYC strain, and was unable to infect systemically the four tested cultivars, Desiree, Maris Bard, King Edward, and Russet Norkotah. Phylogenetic analysis of H14 and the whole genomes of 31 PVY isolates of non-recombinant strains of PVY placed PVY-H14 in the same clade with PVYC and several unclassified PVY isolates from tomato and tobacco.
