Genomic analysis reveals MATH gene(s) as candidate(s) for Plum pox virus (PPV) resistance in apricot (Prunus armeniaca L.).

ABSTRACT: Sharka disease, caused by Plum pox virus (PPV), is the most important viral disease affecting Prunus species. A major PPV resistance locus (PPVres) has been mapped to the upper part of apricot (Prunus armeniaca) linkage group 1. In this study, a physical map of the PPVres locus in the PPV-resistant cultivar 'Goldrich' was constructed. Bacterial artificial chromosome (BAC) clones belonging to the resistant haplotype contig were sequenced using 454/GS-FLX Titanium technology. Concurrently, the whole genome of seven apricot varieties (three PPV-resistant and four PPV-susceptible) and two PPV-susceptible apricot relatives (P. sibirica var. davidiana and P. mume) were obtained using the Illumina-HiSeq2000 platform. Single nucleotide polymorphisms (SNPs) within the mapped interval, recorded from
