Polygenic discrimination of leaf morphotypes in alpine <i>Heldreichia bupleurifolia</i> (Brassicaceae) across its natural range

Our findings suggest that genetic differentiation among morphotypes may involve stress-related processes, particularly ion transport and homeostasis. The enrichment of these functions among candidate loci, alongside observed correlations between morphotypes and substrate types, also hints at a possible contribution of edaphic conditions. While these associations are correlative and require further validation, they underscore potential links between genotype, phenotype, and environment, and highlight the value of integrating genomic and ecological data in alpine plant conservation.
