10.1601/nm.5000 is a rod-shaped facultative anaerobic spore forming bacterium of the genus 10.1601/nm.4857. The defining feature of the species is the ability to produce parasporal crystal inclusion bodies, consisting of δ-endotoxins, encoded by -genes. Here we present the complete annotated genome sequence of the nematicidal 10.1601/nm.5000 strain MYBT18246. The genome comprises one 5,867,749 bp chromosome and 11 plasmids which vary in size from 6330 bp to 150,790 bp. The chromosome contains 6092 protein-coding and 150 RNA genes, including 36 rRNA genes. The plasmids encode 997 proteins and 4 t-RNA's. Analysis of the genome revealed a large number of mobile elements involved in genome plasticity including 11 plasmids and 16 chromosomal prophages. Three different nematicidal toxin genes were identified and classified according to the Cry toxin naming committee as 13Aa2, 13Ba1, and 13Ab1. Strikingly, these genes are located on the chromosome in close proximity to three separate prophages. Moreover, four putative toxin genes of different toxin classes were identified on the plasmids p120510 (Vip-like toxin), p120416 (Cry-like toxin) and p109822 (two Bin-like toxins). A comparative genome analysis of 10.1601/nm.5000 MYBT18246 with three closely related 10.1601/nm.5000 strains enabled determination of the pan-genome of 10.1601/nm.5000 MYBT18246, revealing a large number of singletons, mostly represented by phage genes, morons and cryptic genes.
10.1601/nm.5000是10.1601/nm.4857属的一种杆状兼性厌氧产芽孢细菌。该物种的决定性特征是能够产生由δ-内毒素组成的伴胞晶体包涵体,这些δ-内毒素由相关基因编码。在此,我们展示了杀线虫10.1601/nm.5000菌株MYBT18246的完整注释基因组序列。该基因组由一条5,867,749 bp的染色体和11个质粒组成,质粒大小从6330 bp到150,790 bp不等。染色体包含6092个蛋白质编码基因和150个RNA基因,其中包括36个rRNA基因。这些质粒编码997种蛋白质和4个tRNA。对该基因组的分析揭示了大量参与基因组可塑性的移动元件,包括11个质粒和16个染色体前噬菌体。鉴定出三种不同的杀线虫毒素基因,并根据Cry毒素命名委员会的分类标准将其分类为13Aa2、13Ba1和13Ab1。值得注意的是,这些基因位于染色体上,与三个独立的前噬菌体紧密相邻。此外,在质粒p120510(类Vip毒素)、p120416(类Cry毒素)和p109822(两种类Bin毒素)上鉴定出了四种不同毒素类别的推定毒素基因。对10.1601/nm.5000 MYBT18246与三个密切相关的10.1601/nm.5000菌株进行比较基因组分析,确定了10.1601/nm.5000 MYBT18246的泛基因组,揭示了大量的单拷贝基因,其中大部分由噬菌体基因、插入序列和隐蔽基因组成。
