Genomic variants of genes associated with three horticultural traits in apple revealed by genome re-sequencing.

ABSTRACT: The apple (Malus × domestica Borkh.) cultivar 'Su Shuai' exhibits greater disease resistance, shorter internodes and lighter fruit flavor compared with its parents 'Golden Delicious' and 'Indo'. To obtain a comprehensive overview of the sequence variation in these three horticultural traits, the genomes of 'Su Shuai' and 'Indo' were resequenced using next-generation sequencing and compared to the genome of 'Golden Delicious'. A wide range of genetic variations were detected, including 2 454 406 and 18 749 349 single nucleotide polymorphism (SNP) and 59 547 and 50 143 structural variants (SVs) in the 'Indo' and 'Su Shuai' genomes, respectively. Among the SVs in 'Su Shuai', 17 genes related to disease resistance, 10 genes related to Gibberellin (GA) and 19 genes associated with fruit flavor
