Background. Tulipa species are economically, culturally, scientifically, and ecologically important. Tulips present taxonomic complexities that cannot be adequately resolved by examining their morphological characteristics alone or by relying on a limited selection of genetic markers. Methods. In the present study, we assessed the complete plastid sequences of Tulipa alberti Regel and Tulipa greigii Regel collected from Kazakhstan. Additionally, 14 previously published plastomes were obtained from GenBank for comparison and phylogenetic analysis. Results. The plastid genome sizes of T. alberti and T. greigii were 152,359 bp and 152,242 bp, respectively. In the plastid genomes of T. alberti and T. greigii, 136 genes were annotated, 114 of which were unique. These unique genes comprised eighty protein-coding, thirty transfer RNA, and four ribosomal RNA genes. Additionally, 415 simple sequence repeats were identified, comprising 107 tandem, 40 forward, 49 palindromic, 8 reverse, and 1 complementary repeat. Notably, the region containing ycf1 exhibited high variability and may serve as an informative DNA barcode for this genus. Conclusion. Phylogenetic analysis showed strong support for the relationships among Tulipa species, indicating the utility of plastid genome data for further taxonomic studies within the genus.
