Populus pruinosa Genome sequencing and assembly

Populus pruinosa, owing high tolerant ability to arid, saline and alkaline desert, is an attractive model for studying ecological adaptation and speciation in extreme environments. Here, a chromosome-level reference genome of P. pruinosa (v2.0) with 521.09 Mb and a contig N50 of 21.06 Mb by combining PacBio sequencing with Hi-C technologies were reported. Our aim was to (i) build a chromosome-level reference genome; and (ii) investigate the population structure and geographic distribution model of P. pruinosa. Our study would facilitate future genomics-assisted genetic improvement and conservation efforts for the endangered species.
