The chromosome-level wintersweet (Chimonanthus praecox) genome provides insights into floral scent biosynthesis and flowering in winter

摘要

Wintersweet flower morphology, genome features, and synteny information. a Wintersweet flower blooming in winter. b Overview of the wintersweet draft genome assembly. The outer layer of colored blocks represents the 11 pseudomolecules, with tick marks every 5 Mb in size (i). Tracks displayed are as follows: (ii–v) the density of genes, long interspersed nuclear elements, long terminal repeat retrotransposons and DNA elements; (vi) guanine-cytosine (GC) content; (vii) relationship between syntenic blocks, as indicated by lines. All the colored bands were featured in 1-Mb intervals across the chromosomes
