Analysis of gene expansion and defense-related genes in Anacardiaceae family from an evolutionary aspect

This study unveils TE-mediated diversification as a key driver of Anacardiaceae evolution, complementing WGD-dependent strategies in tropical lineages. The identification of lineage-specific structural variations, dynamic TE activities, and clustered defense-related genes highlights adaptive trade-offs shaped by biotic stresses and the biogeographic history of Anacardiaceae species. This study lays the groundwork for leveraging these genomic resources to enhance stress resilience and adaptive potential in economically important Anacardiaceae crops.
