Candidate genes associated with red colour formation revealed by comparative genomic variant analysis of red- and green-skinned fruits of Japanese apricot (Prunus mume).

ABSTRACT: The red-skinned fruit of Japanese apricot (Prunus mume Sieb. et Zucc) appeals to customers due to its eye-catching pigmentation, while the mechanism related to its colour formation is still unclear. In this study, genome re-sequencing of six Japanese apricot cultivars was carried out with approximately 92.2 Gb of clean bases using next-generation sequencing. A total of 32,004 unigenes were assembled with an average of 83.1% coverage rate relative to reference genome. A wide range of genetic variation was detected, including 7,387,057 single nucleotide polymorphisms, 456,222 insertions or deletions and 129,061 structural variations in all genomes. Comparative sequencing data revealed that 13 candidate genes were involved in biosynthesis of anthocyanin. Significantly higher expression
