SOMmelier Maps Grapevine Genetic Components Topologically
Researchers (Baloyan et al.) published Feb 20, 2026 in PLoS Computational Biology applied SOMmelier, a Self-Organizing Map tool, to genotype data from European grapevine to compare with ADMIXTURE up to six components. SOMmelier recovered admixture-derived genetic components and produced a topology-aware 2D genetic landscape reflecting geographic domestication patterns; method generalizes to other species for population-structure and trait-association analyses.
Scoring Rationale
Peer-reviewed, reusable SOM method with clear population-genetics relevance; novelty limited to methodological integration and single-species demonstration.
