Abstract

Peppermint, Mentha × piperita L., is a hexaploid (2n = 6x = 72) and the predominant cultivar of commercial mint oil production in the US. This cultivar is threatened because of high susceptibility to the fungal disease verticillium wilt, caused by Verticillium dahliae. This report details the first draft polyploid chromosome-level genome assembly for this mint species. The "Mitcham" genome resource will broaden comparative studies of disease resistance, essential oil biosynthesis, and hybridization events within the genus Mentha. It will also be a valuable contribution to the body of phylogenetic studies involving Mentha and other genera that contain species with varying ploidy levels.

摘要

薄荷（Mentha × piperita L.）是一种六倍体植物（2n = 6x = 72），也是美国商业薄荷油生产的主要栽培品种。由于对由大丽轮枝菌引起的真菌病害黄萎病高度敏感，该品种正受到威胁。本报告详细介绍了该薄荷物种的首份多倍体染色体水平基因组组装草图。“米奇姆”基因组资源将拓宽对薄荷属内抗病性、精油生物合成和杂交事件的比较研究。它也将为涉及薄荷属以及其他包含不同倍性水平物种的属的系统发育研究做出宝贵贡献。
