Data from: Draft Genome Assembly of Passalora sequoiae a Needle Blight Pathogen on Leyland Cypress

Published by Agricultural Research Service | Department of Agriculture | Metadata Last Checked: June 24, 2025 | Last Modified: 2025-05-06
<p>The objective was to generate a high-quality draft assembly of the whole genome as a resource for future applications such as temporal and spatial dispersal studies of the pathogen and to investigate genotype diversity relevant in fungicide resistance studies and cypress breeding programs. We report here the genome sequence of <em>Passalora sequoiae</em> 9LC2 that was isolated from Leyland cypress 'Leighton Green' (<em>Cupressocyparis leylandii</em>) in 2017 in southern Mississippi. The draft genome was obtained using Pacific Biosciences (PacBio) SMRT and Illumina HiSeq 2500 sequencing. Illumina reads were mapped to PacBio assembled contigs to determine base call consistency. Based on a total of 44 contigs with 722 kilobase (kb) average length (range 9.4 kb to 3.4 Mb), the whole genome size was estimated at 31,768,716 bp. Mapping of Illumina reads to PacBio contigs resulted in a 1000 x coverage and were used to confirm accuracy of the consensus sequences.</p> <p>The figures and methods files are documentation in support of a BMC Data Notes publication 'Draft Genome Assembly of <em>Passalora sequoiae</em> a Needle Blight Pathogen on Leyland Cypress'.
