High quality genome of Erigeron breviscapus provides a reference for herbal plants in Asteraceae.

ABSTRACT: Erigeron breviscapus is an important medicinal plant in Compositae and the first species to realize the whole process from the decoding of the draft genome sequence to scutellarin biosynthesis in yeast. However, the previous low-quality genome assembly has hindered the optimization of candidate genes involved in scutellarin synthesis and the development of molecular-assisted breeding based on the genome. Here, the E. breviscapus genome was updated using PacBio RSII sequencing data and Hi-C data, and increased in size from 1.2 Gb to 1.43 Gb, with a scaffold N50 of 156.82 Mb and contig N50 of 140.95 kb, and a total of 43,514 protein-coding genes were obtained and oriented onto nine pseudo-chromosomes, thus becoming the third plant species assembled to chromosome level after sunflower and let
