Genome assemblies of the sugarcane orange rust fungal pathogen Puccinia kuehnii

<em>Puccinia kuehnii</em>is an obligate biotrophic fungal pathogen that causes orange rust of sugarcane, which is prevalent in many countries around the globe. In the USA, orange rust was first detected in sugarcane in Florida in 2007 and poses a persistent and economically damaging threat to the sugarcane industry in this region. Here, we generated the first genome assemblies for two isolates of <em>P. kuehnii </em>(1040 and 2143) collected in Florida in 2017 from two sugarcane cultivars, CL85-1040 and CP89-2143, respectively. These two rust genome resources will be of immense value for future genomic studies, particularly further exploration of the predicted secretomes that may help define key pathogenicity determinants for this economically important pathogen.屈恩柄锈菌（*Puccinia kuehnii*）是专性活体营养型真菌病原菌，可引发甘蔗橙锈病，在全球多国均有分布。美国方面，橙锈病于2007年首次在佛罗里达州的甘蔗种植体系中被检出，对该地区甘蔗产业造成持续且极具经济破坏性的威胁。本研究首次完成了两株屈恩柄锈菌分离菌株的基因组组装，这两株菌株分别编号为1040与2143，于2017年采自佛罗里达州，其宿主分别为甘蔗品种CL85-1040与CP89-2143。这两份锈菌基因组资源将为后续基因组学研究提供极高的研究价值，尤其是针对预测分泌组的进一步探索，或可帮助明确这一经济重要性病原菌的关键致病决定因子。
