Black Sigatoka disease, caused by the fungus , is one of the most devastating diseases of banana around the world. Fungicide applications are the primary tool used to manage black Sigatoka, but fungicide resistance in , as in other fungal pathogens, is one of the major limitations in the efficient management and prevention of this disease. In the current study, we present the draft genome of strain IIL-20, the first genomic sequence published from a strain of this fungus isolated in North America. Bioinformatic analysis showed putative genes involved in fungus virulence and fungicide resistance. These findings may lead us to a better understanding of the molecular pathogenesis of this fungal pathogen and also to the discovery of the mechanisms conferring fungicide resistance.
黑星病由真菌引起，是全球香蕉最具破坏性的疾病之一。杀菌剂的应用是防治黑星病的主要手段，但与其他真菌病原体一样，杀菌剂抗性是有效管理和预防这种疾病的主要限制因素之一。在本研究中，我们展示了菌株 IIL-20 的草图基因组，这是第一个从北美的该真菌分离株中发表的基因组序列。生物信息学分析显示了与真菌毒力和杀菌剂抗性相关的假定基因。这些发现可能使我们更好地了解这种真菌病原体的分子发病机制，并发现赋予杀菌剂抗性的机制。
