Genome sequencing and analysis of two early-flowering cherry (Cerasus × kanzakura) varieties, 'Kawazu-zakura' and 'Atami-zakura'.

ABSTRACT: To gain genetic insights into the early-flowering phenotype of ornamental cherry, also known as sakura, we determined the genome sequences of two early-flowering cherry (Cerasus × kanzakura) varieties, 'Kawazu-zakura' and 'Atami-zakura'. Because the two varieties are interspecific hybrids, likely derived from crosses between Cerasus campanulata (early-flowering species) and Cerasus speciosa, we employed the haplotype-resolved sequence assembly strategy. Genome sequence reads obtained from each variety by single-molecule real-time sequencing (SMRT) were split into two subsets, based on the genome sequence information of the two probable ancestors, and assembled to obtain haplotype-phased genome sequences. The resultant genome assembly of 'Kawazu-zakura' spanned 519.8 Mb with 1,544 contigs a
