Diversity of the Ry_sto gene conferring resistance to potato virus Y in wild relatives of potato.

ABSTRACT:

Background

Potato virus Y (PVY) is among the economically most damaging viral pathogen in production of potato (Solanum tuberosum) worldwide. The gene Ry_sto derived from the wild potato relative Solanum stoloniferum confers extreme resistance to PVY.

Results

The presence and diversity of Ry_sto were investigated in wild relatives of potato (298 genotypes representing 29 accessions of 26 tuber-bearing Solanum species) using PacBio amplicon sequencing. A total of 55 unique Rysto-like sequences were identified in 72 genotypes representing 12 accessions of 10 Solanum species and six resistant controls (potato cultivars Alicja, Bzura, Hinga, Nimfy, White Lady and breeding line PW363). The 55 Rysto-like sequences showed 89.87 to 99.98% nucleotide identity to t
