The complete plastid genome of Seseli giganteum Lipsky (Apiaceae), an endemic species of the Kyrgyz Republic

Seseli giganteum Lipsky, an endemic Apiaceae species from the Kyrgyz Republic, was characterized based on its complete plastid genome. The circular genome is 147,554 bp long and exhibits a typical quadripartite structure, comprising an LSC (92,927 bp), SSC (17,631 bp), and two IRs (18,498 bp each). Phylogenetic analyses using 79 plastid protein-coding genes under maximum likelihood and Bayesian inference yielded highly congruent trees with strong support. The results indicate that Seseli L. is non-monophyletic, with Ligusticum L. and Peucedanum L. nested within it. S. giganteum is sister to S. valentinae Popov, highlighting a close Central Asian relationship and suggesting a need to reassess generic boundaries.
