Banana tree bacterial wilt is caused by the Ralstonia solanacearum Moko ecotype. These strains vary in their symptom progression in banana, and are classified as typical Moko variants (phylotype IIA and IIB strains from across Central and South America), Bugtok variant (Philippines), and Sergipe facies (the states of Sergipe and Alagoas, Brazil). This study used comparative genomic and phylogenomic approaches to identify a correlation between the symptom progression of the Moko ecotypes based on the analysis of 23 available genomes.

Transcriptomic data of 19 Sequence Read Archive runs available at GenBank, as well as RNA-seq data generated from onion tissue from fields in Brazil were used to assemble nine allium cepa amalgavirus 1 (AcAV-1) and nine allium cepa amalgavirus 2 (AcAV-2) genomes from different species of allium worldwide. Sequence demarcation tool analyses of RdRp amino acid sequences revealed identities above 99% within each species, except for an isolate of AcAV-1 from Allium escalonicum from China.

Article Synopsis
- - The study explores the genomes of different strains of Ralstonia solanacearum, the bacteria responsible for banana vascular wilt (Moko), focusing on various ecotypes from Brazil.
- - Genome analysis revealed a high genetic similarity (>96%) among the strains, highlighting significant clusters in both chromosomes and megaplasmids, with a total of 3,378 chromosomal clusters identified.
- - Unique genomic features were found in strains CCRMRsB7 and CCRMRs287, with CCRMRsB7 having the largest genome recorded, providing valuable insights for the future identification and study of Moko ecotypes.
Genomic sequencing of two isolates of Ralstonia solanacearum causing Sergipe facies and comparative analysis with Bugtok disease isolates.

Article Synopsis
- Ralstonia solanacearum causes Moko disease in bananas, specifically manifesting as "Sergipe facies" in northeastern Brazil, which has symptoms akin to Bugtok disease found in the Philippines.
- The study sequenced and analyzed the genomes of two isolates linked to Sergipe facies (SFC and IBSBF2570) and compared them to Bugtok disease isolates, revealing that the Sergipe facies genomes were 5.58 Mb and 5.46 Mb in length across 185 and 174 contigs.
- Despite high genomic similarity between Sergipe facies and Bugtok disease isolates, Bugtok isolates showed a greater diversity in gene clusters, suggesting a longer interaction period may contribute to their
