Assemblies, associated annotation files, and analysis source data of Platanus x acerifloia genome

Platanus × acerifolia (London plane; Platanaceae) is a major ornamental tree used worldwide. Platanaceae is one of the last early-diverging eudicot families without a complete nuclear genome assembly. Here, we assembled a high-quality, chromosome-level reference genome for P. × acerifolia., Genome and transcriptome sequencing The extracted genomic DNA met the requirement for both Illumina (San Diego, CA, USA) sequencing and PacBio High Fidelity (HiFi; Covaris, Massachusetts, USA) sequencing (Supplementary Note 2.2). For Illumina sequencing of the P. × acerifolia genome, a 350-bp library was constructed and sequenced on the Illumina NovaSeq platform. The approximately 10-kb SMRTbellTM libraries were constructed for single-molecule sequencing with PacBio; the data generated were used to assemble the highly heterogeneous P. × acerifolia polyploid genome. The HiFi reads were sequenced using the PacBio Sequel II system following PacBioTM standard protocol. To anchor genome scaffolds onto chromosomes, we also constructed a Hi-C library and obtained sequence data via the MGI-SEQ 2000 platform (Wuhan, Hubei, China). In brief, fresh leaves were fixed with a nuclei isolation buffer containing 2% formaldehyde following previously reported methods. The DNA was digested with DpnII.
