Genomic DNA was extracted from Ralstonia solanacearum strains cultured in Casamino Acid-Peptone-Glucose (CPG) medium for 48 hours at room temperature. Long-read sequencing libraries were prepared by Plasmidsaurus using the Oxford Nanopore Technologies (ONT) Rapid Barcoding Kit 96 V14 (SQK-RBK114.96). Sequencing was performed on a PromethION 24 platform using R10.4.1 flow cells. High-accuracy basecalling was executed using ONT Dorado-for-PromethION (v7.4.12) in super-high accuracy (SUP) mode to generate long reads for hybrid genome assembly.
