pv. is the causal agent of bacterial blight, one of the most devastating diseases of rice. Here, a hypervirulent strain, C9-3, defeating , , , and resistance genes, was used to extract genomic DNA for single molecule real-time (SMRT) sequencing. After assembly, the genome consists of a single-circular chromosome with the size of 4,924,298 bp with G+C content of 63.7% and contains 4,715 genes. Annotation and analysis of the genes using a suite of applications named AnnoTALE suggested that 17 transcription activator-like effectors, including 15 typical TALEs and 2 iTALEs/truncTALEs, were encoded in the genome. The approach and genome resource will contribute to the discovery of new virulence effectors and understanding on rice-. pv. interactions.
pv. 是细菌性枯萎病的病原体,这是水稻最具破坏性的疾病之一。在这里,使用了一种高毒力菌株 C9-3 来提取基因组 DNA 进行单分子实时 (SMRT) 测序。组装后,基因组由一个大小为 4924298bp 的单环染色体组成,G+C 含量为 63.7%,包含 4715 个基因。使用名为 AnnoTALE 的一套应用程序对 基因进行注释和分析表明,该基因组编码了 17 个转录激活样效应子,包括 15 个典型的 TALEs 和 2 个 iTALEs/truncTALEs。该方法和基因组资源将有助于发现新的毒力效应子,并深入了解水稻与. pv. 的相互作用。
