Chromosome-scale genome assembly of Eustoma grandiflorum, the first complete genome sequence in the genus Eustoma.

ABSTRACT: Eustoma grandiflorum (Raf.) Shinn. is an annual herbaceous plant native to the southern United States, Mexico, and the Greater Antilles. It has a large flower with a variety of colors and is an important flower crop. In this study, we established a chromosome-scale de novo assembly of E. grandiflorum genome sequences by integrating four genomic and genetic approaches: (1) Pacific Biosciences (PacBio) Sequel deep sequencing, (2) error correction of the assembly by Illumina short reads, (3) scaffolding by chromatin conformation capture sequencing (Hi-C), and (4) genetic linkage maps derived from an F2 mapping population. Thirty-six pseudomolecules and 64 unplaced scaffolds were created, with a total length of 1,324.8 Mb. A total of 36,619 genes were predicted on the genome as high-confidence
