Insights from the first chromosome-level genome assembly of the alpine gentian Gentiana straminea Maxim.

ABSTRACT: Gentiana straminea Maxim. is a perennial herb and mainly distributed in the Qinghai-Tibetan Plateau. To adapt to the extreme environment, it has developed particular morphological, physiological, and genetic structures. Also, rich in iridoids, it is one of the original plants of traditional Chinese herb 'Qinjiao'. Herein, we present its first chromosome-level genome sequence assembly and compare it with the genomes of other Gentiana species to facilitate the analysis of genomic characteristics. The assembled genome size of G. straminea was 1.25 Gb, with a contig N50 of 7.5 Mb. A total of 96.08% of the genome sequences was anchored on 13 pseudochromosomes, with a scaffold N50 of 92.70 Mb. A total of 54,310 protein-coding genes were predicted, 80.25% of which were functionally annotated. Com
