Genome structure of Rosa multiflora, a wild ancestor of cultivated roses.

ABSTRACT: The draft genome sequence of a wild rose (Rosa multiflora Thunb.) was determined using Illumina MiSeq and HiSeq platforms. The total length of the scaffolds was 739,637,845 bp, consisting of 83,189 scaffolds, which was close to the 711 Mbp length estimated by k-mer analysis. N50 length of the scaffolds was 90,830 bp, and extent of the longest was 1,133,259 bp. The average GC content of the scaffolds was 38.9%. After gene prediction, 67,380 candidates exhibiting sequence homology to known genes and domains were extracted, which included complete and partial gene structures. This large number of genes for a diploid plant may reflect heterogeneity of the genome originating from self-incompatibility in R. multiflora. According to CEGMA analysis, 91.9% and 98.0% of the core eukaryotic genes wer
