The genus Alyssum L., one of the largest genera within the Brassicaceae family, comprises ~ 170–190 species distributed worldwide. To date, 35 taxa have been identified in Iran, including 28 species and 7 varieties. In traditional medicine, several Alyssum species have been used as anti-rabies, as sedatives, treating hiccups and coughs. To elucidate the phylogenetic relationships among 42 Alyssum species, including 16 species from Iran and 26 from other regions, the internal transcribed spacer (ITS) region of nuclear ribosomal DNA was analyzed. Phylogenetic trees were constructed using both maximum likelihood and maximum parsimony methods, yielding largely congruent topologies. The analyses resolved two primary clades within the genus. Notably, this study represents the first report of ITS sequence data for 16 Iranian Alyssum species. The findings of this study support the monophyletic nature of the Alyssum section and highlight a polytomy within the Odontarrhena and Meniocus sections. These results contribute valuable insights into the taxonomy and phylogenetic structure of Alyssum in Iran and provide a robust foundation for future ecological and biochemical investigations. |
