Horizontal Gene Transfer Events in Five Euplotes Ciliate Genomes

Five genome-sequenced Euplotes ciliate species were analyzed for bacterial horizontal gene transfer (HGT). The dataset contains results identifying 342 HGT-acquired genes with functional annotations. Ruanlin Wang published this analysis in April 2026.

Use Cases

• Classify HGT-acquired genes by function using Pfam, GO, and KEGG database annotations from the table.
• Analyze genomic features like GC content, intron proportion, and CDS length to infer the age of HGT events.
• Identify putative endosymbiont-derived genes, such as the five glycoside hydrolase genes from E. vannus.
• Study gene expression validation data, including qPCR results for mannan endo-1,4-β-mannosidase (Man) genes in E. amieti.
• Examine the phylogenetic distribution of the seven HGT families putatively transferred into the last common ancestor of all five Euplotes.

Strengths

• Systematic analysis across five distinct Euplotes genomes provides comparative data.
• Identifies 342 HGT-acquired genes with diverse functional annotations (e.g., carbohydrate metabolism, sulfur metabolism).
• Includes experimental validation data from qPCR and RNAi for key gene functions.

Limitations

• The dataset is very small at 11.1 KB, indicating limited raw data or summary-level results only.
• Analysis is restricted to only five Euplotes species, limiting broader evolutionary conclusions.
• Specific column names and row counts for the tabular data are not provided in the metadata.
