The Chromosome Level Genome and Genome-wide Association Study for the Agronomic Traits of Panax Notoginseng.

ABSTRACT: The Chinese ginseng Panax notoginseng is a domesticated herb with significant medicinal and economic value. Here we report a chromosome-level P. notoginseng genome assembly with a high (∼79%) repetitive sequence content. The juxtaposition with the widely distributed, closely related Korean ginseng (Panax ginseng) genome revealed contraction of plant defense genes (in particular R-genes) in the P. notoginseng genome. We also investigated the reasons for the larger genome size of Panax species, revealing contributions from two Panax-specific whole-genome duplication events and transposable element expansion. Transcriptome data and comparative genome analysis revealed the candidate genes involved in the ginsenoside synthesis pathway. We also pe
