Résumé
Sassafras tzumu, an elegant deciduous arboreal species, belongs to the esteemed genus Sassafras within the distinguished family Lauraceae. With its immense commercial value, escalating market demands and unforeseen human activities within its natural habitat have emerged as new threats to S. tzumu in recent decades, so it is necessary to study its genetic diversity and influencing factors, to propose correlative conservation strategies. By utilizing genotyping-by-sequence (GBS) technology, we acquired a comprehensive database of single nucleotide polymorphisms (SNPs) from a cohort of 106 individuals sourced from 13 diverse Sassafras tzumu natural populations, scattered across various Chinese mountainous regions. Through our meticulous analysis, we aimed to unravel the intricate genetic diversity and structure within these S. tzumu populations, while simultaneously investigating the various factors that potentially shape genetic distance. Our preliminary findings unveiled a moderate level of genetic differentiation (F The genetic variance among populations of S. tzumu in our investigation exhibited a moderate degree of differentiation, alongside a heightened level of genetic diversity. The environmental distance of S. tzumu had a greater impact on its genetic diversity than geographical distance. It is of utmost significance to formulate and implement meticulous management and conservation strategies to safeguard the invaluable genetic resources of S. tzumu.

CONCLUSIONS
The genetic variance among populations of S. tzumu in our investigation exhibited a moderate degree of differentiation, alongside a heightened level of genetic diversity. The environmental distance of S. tzumu had a greater impact on its genetic diversity than geographical distance. It is of utmost significance to formulate and implement meticulous management and conservation strategies to safeguard the invaluable genetic resources of S. tzumu.
