Zearalenone (ZEN) is a widely distributed mycotoxin that frequently contaminates crops and animal feed. Our previous studies showed that a new strain, Stappia sp. WLB 29 with a 97.47% of similarity to Stappia indica B106, isolated from the soil samples in the rhizosphere of the crops in Xinjiang, was capable of effectively degrading ZEN in minimal medium. In this study, we determined the complete genomic sequence of the Stappia sp. WLB 29 (Genbank accession number: JALBGD000000000; BioProject ID in GenBank is PRJNA814005). The total length of all sequences was 4,745,415 bp with a GC content of 67.08%. Moreover, the genome-wide analysis showed the presence of laccase- and peroxiredoxin-encoding genes in Stappia sp. WLB 29, which may be associated with ZEN degradation. The genome sequence of Stappia sp. WLB 29 reported here will serve as a reference for comparative genomic studies of ZEN degradation in the feed and food industry.
玉米赤霉烯酮（ZEN）是一种广泛分布的真菌毒素，经常污染农作物和动物饲料。我们之前的研究表明，从新疆农作物根际土壤样本中分离到的一株与印度 Stappia indica B106 相似度为 97.47%的新菌株 Stappia sp. WLB 29 能够有效地在最小培养基中降解 ZEN。在本研究中，我们确定了 Stappia sp. WLB 29 的完整基因组序列（Genbank 登录号：JALBGD000000000；GenBank 中的生物项目 ID 是 PRJNA814005）。所有序列的总长度为 4745415bp，GC 含量为 67.08%。此外，全基因组分析表明，Stappia sp. WLB 29 中存在漆酶和过氧化物酶编码基因，这可能与 ZEN 降解有关。本研究报道的 Stappia sp. WLB 29 基因组序列将为饲料和食品工业中 ZEN 降解的比较基因组研究提供参考。
