Abstract

The study of endemic species provides valuable perspectives on evolutionary history and future targets for their conservation. Salix purpurea L. subsp. leucodermis Yalt., which is endemic to Sandras Mountain in Türkiye, was analysed using morphological, anatomical, and genomic methods. This study presents the first draft short-read sequence of S. purpurea subsp. leucodermis, providing preliminary genomic evidence of differentiation from related taxa. This study also revealed a specific combination of anatomical features (prominent calcium oxalate crystals and amphistomatous leaves) and morphological characteristics (striated wood, glabrous buds, absence of stipules) that differentiate the taxon in question from the closely related species S. amplexicaulis, S. elbrusensis and S. purpurea.  The results of genomic analyses identified patterns of sequence variation, a high number of unique paralogs (6,790), and putative structural variations (translocations and duplications) as well as lineage-specific transposable elements, supporting its evolutionary divergence. An identification key based on morphological and anatomical characters is presented. Consequently, based on the results of this multidisciplinary research the taxonomic status of S.purpurea subsp. leucodermis was elevated to species level: S. leucodermis (Yalt.) P.Acar & I.V.Belyaeva.
