Abstract

, a plant pathogen, is primarily transmitted through contaminated seeds and insect vectors, with the corn flea beetle () being the primary carrier. is a bacterium belonging to the order and can lead to crop diseases that have a significant economic impact worldwide. Due to its high potential for spread, is classified as a quarantine organism in numerous countries. Despite its impact on agriculture, the limited genome sequences of hamper understanding of its pathogenicity and host specificity, and the development of effective control strategies. In this study, a strain (C10109_Jinnung) was discovered in the faecal matter of the Critically Endangered western ground parrot/kyloring () in Australia, which to our knowledge is the first reported genome from a bird source. Whole-genome sequencing and phylogenomic analysis of strain C10109_Jinnung, obtained from a captive psittacine, provides new insights into the genetic diversity and potential transmission route for the spread of beyond insects and plants, where is typically studied. Our findings provide new insights into the potential transmission route for spread of and expand the known transmission agents beyond insects and plants. Expanding the catalogue of genomes is fundamental to improving understanding of the pathogenicity, evolution and dissemination, and to develop effective control strategies to reduce the substantial economic losses associated with in various crops and the potential impact of endangered animal species.

摘要

玉米细菌性枯萎病菌,一种植物病原菌,主要通过受污染的种子和昆虫媒介传播,其中玉米叶甲()是主要的携带者。玉米细菌性枯萎病菌是一种属于肠杆菌目的细菌,可导致全球范围内对农作物具有重大经济影响的疾病。由于其具有高度传播的潜力,因此在许多国家被列为检疫性生物。尽管对农业有影响,但玉米细菌性枯萎病菌的有限基因组序列阻碍了对其致病性和宿主特异性的理解,以及有效的控制策略的发展。在这项研究中,在澳大利亚濒临灭绝的西部地面鹦鹉/金莺()的粪便中发现了一株玉米细菌性枯萎病菌(C10109_Jinnung)菌株,据我们所知,这是首次从鸟类来源报告的玉米细菌性枯萎病菌基因组。从圈养鹦鹉中获得的菌株 C10109_Jinnung 的全基因组测序和系统发育分析,为玉米细菌性枯萎病菌在昆虫和植物之外的传播提供了新的见解,因为通常在昆虫和植物之外研究玉米细菌性枯萎病菌。我们的研究结果为玉米细菌性枯萎病菌的传播提供了新的潜在传播途径,并扩展了已知的传播媒介,超出了昆虫和植物。扩展玉米细菌性枯萎病菌的基因组目录对于提高对其致病性、进化和传播的理解,以及开发有效的控制策略以减少与各种作物相关的重大经济损失以及濒危动物物种的潜在影响至关重要。
