Pseudo-chromosome–length genome assembly of a double haploid “Bartlett” pear (Pyrus communis L.)

Background We report an improved assembly and scaffolding of the European pear (Pyrus communis L.) genome (referred to as BartlettDHv2.0), obtained using a combination of Pacific Biosciences RSII long-read sequencing, Bionano optical mapping, chromatin interaction capture (Hi-C), and genetic mapping. The sample selected for sequencing is a double haploid derived from the same “Bartlett” reference pear that was previously sequenced. Sequencing of...
