Abstract

Ralstonia solanacearum is an extremely destructive pathogen able to cause disease in a wide range of host plants. Here we report the draft genome sequences of the strains FJAT-91, FJAT-452 and FJAT-462, isolated from tomato, eggplant, and chili pepper, respectively, in China. In addition to the genome annotation, we performed a search for type-III secreted effectors in these strains, providing a detailed annotation of their presence and distinctive features compared to the effector repertoire of the reference phylotype I strain (GMI1000). In this analysis, we found that each strain has a unique effector repertoire, encoding both strain-specific effector variants and variations shared among all three strains. Our study, based on strains isolated from different hosts within the same geographical location, provides insight into effector repertoires sufficient to cause disease in different hosts, and may contribute to the identification of host specificity determinants for R. solanacearum.

从中国番茄、茄子和辣椒中分离出的茄属拉氏菌系统I型菌株FJAT-91、FJAT-452和FJAT-462的基因组测序和分析。

Ralstonia solanacearum 是一种破坏性极强的病原菌，可导致多种寄主植物发病。在此，我们报告了分别从中国番茄、茄子和辣椒中分离出的菌株 FJAT-91、FJAT-452 和 FJAT-462 的基因组序列草案。除了基因组注释外，我们还对这些菌株中的 III 型分泌效应物进行了搜索，详细注释了这些效应物的存在以及与参考系统I型菌株（GMI1000）的效应物库相比的独特特征。在这项分析中，我们发现每个菌株都有一个独特的效应物剧目，既有菌株特异的效应物变体，也有所有三个菌株共有的变体。我们的研究基于从同一地理位置的不同寄主中分离的菌株，有助于深入了解足以在不同寄主中致病的效应物复合物，并可能有助于确定茄属酵母菌的寄主特异性决定因素。
