Hippophae goniocarpa Genome sequencing and assembly
Hippophae goniocarpa is a diploid homoploid hybrid species endemic to the Qinghai-Tibet Plateau, originating from natural hybridization between Hippophae rhamnoides ssp. sinensis and Hippophae neurocarpa. It is an excellent material to investigate homoploid hybrid speciation and high-altitude adaptation. Here, we applied PacBio long-read sequencing combined with Hi-C technology to construct a chromosome-scale reference genome of H. goniocarpa. This genomic resource fills the existing gap for this hybrid species, supports further research on its hybrid origin, adaptive evolution and comparative genomics within sea buckthorn, and benefits germplasm conservation and genetic improvement of H. goniocarpa.
