Assessing diversity and clonal variation of Australia’s grapevine germplasm: Curating the FALCON-Unzip Chardonnay de novo genome assembly

Until recently only two genome assemblies were publicly available for grapevine—both Vitis vinifera L. Cv. Pinot Noir (PN). The best available PN genome assembly (Jaillon et al. 2007) is not representative of the genome complexity that is typical of wine-grape cultivars in the field and it is highly fragmented. To assess the genetic complexities of Chardonnay grapevine, assembly of a new de novo reference genome was needed. Here we describe a draft assembly using PacBio SMRT Sequencing data and PacBio’s new phased diploid genome assembler FALCON-Unzip (Chin et al. 2016).
