Interpretive Summary:

Technical Abstract: Cultivated carrot (D. carota subsp. sativus) is the most important member in the Apiaceae family in terms of economy and nutrition and is considered the second most popular vegetable in the world after potato. Despite its global importance, the systematics of Daucus remains under active revision both at the species, genus, and subtribal levels. The phylogenetic relationships among the species of Daucus and close relatives in the Apioideae have been clarified recently by a series of molecular studies using DNA sequences of the plastid genes rbcL and matK; plastid introns rpl16, rps16, rpoC1; nuclear ribosomal DNA internal transcribed spacer (ITS) sequences; plastid DNA restriction sites. Of these DNA markers, the ITS region consisting of ITS1, the intervening spacer, and ITS2 has served as the main marker used. Recently, next-generation DNA sequencing methodologies have been used. We review these techniques and how they are impacting the taxonomy of the genus Daucus.
