"The chromosome-level quality genome provides insights into the evolution of the biosynthesis genes for aroma compounds of Osmanthus fragrans"

"The chromosome-level reference genome of O. fragrans was constructed toassist in studies of the evolution, genetic diversity, and molecular mechanism of aroma development. A total of over118 Gb of polished reads was produced from HiSeq (45.1 Gb) and PacBio Sequel (73.35 Gb), giving 100× depthcoverage for long reads. The combination of Illumina-short reads, PacBio-long reads, and Hi-C data produced the finalchromosome quality genome of O. fragrans with a genome size of 727 Mb and a heterozygosity of 1.45 %. Thegenome was annotated using de novo and homology comparison and further refined with transcriptome data. Thegenome of O. fragrans was predicted to have 45,542 genes, of which 95.68 % were functionally annotated. Genomeannotation found 49.35 % as the repetitive sequences, with long terminal repeats (LTR) being the richest (28.94 %)."
