Fusarium avenaceum strain:WV21P1A Genome sequencing and assembly

Fusarium avenaceum is a generalist fungus that can infect many different crops and is a concern for food safety due to its ability to produce toxins. Genome sequences are valuable resources to study fungal biology including the genes involved in the crop infection pathway and genes involved in the production of toxins. Currently, there are 12 available genomes for Fusarium avenaceum. However, all of them were produced using short-read sequencing resulting in fragmented and incomplete genomes sequences. Here, we present a new genome assembly for Fusarium avenaceum that is of higher quality than all other previously released genomes. We accomplished this by using the last long-read sequencing technology to assemble a genome sequence that matches the expected chromosome number and thoroughly annotate the genes. Our annotation also included an analysis of the gene clusters that are associated with toxin and other biochemical production pathways. This genomic resource will facilitate further research on plant pathology, food safety, and Fusarium sp. diversity.

Fusarium avenaceum，一种广谱真菌，可感染多种作物，由于其产生毒素的能力而对食品安全构成威胁。基因组序列是研究真菌生物学，包括参与作物感染途径及毒素生产相关基因的重要资源。目前，已有12个Fusarium avenaceum的基因组序列可供使用。然而，这些基因组序列均通过短读长测序技术获得，导致基因组序列片段化和不完整。在本研究中，我们呈现了一种新的Fusarium avenaceum基因组组装方法，其质量优于所有先前发布的基因组。我们通过应用最新的长读长测序技术，组装了一个与预期染色体数量相匹配的基因组序列，并对基因进行了详尽的注释。我们的注释还包括了对与毒素及其他生化代谢途径相关的基因簇的分析。这一基因组资源将促进植物病理学、食品安全及Fusarium属多样性等领域的进一步研究。
