Investigations on the phylogenetic position of the ditypic genus Froriepia reveal Yildirimlia, a new genus of Apiaceae

Abstract

Froriepia is a ditypic genus in the subfamily Apioideae. Froriepia subpinnata occurs in Iran and the Caucasus, while F. gracillima is a species endemic to Turkey that is known only from the type specimen collected near the country's eastern border. Although many comprehensive phylogenetic studies of members of the family Apiaceae have been conducted, the phylogenetic position of Froriepia has remained unknown. When we examined this genus in detail, we suspected that the two species assigned to it may in fact belong to separate genera because of morphological differences between them. To understand the tribal classification of this genus and to reveal its infrageneric phylogenetic relationships, we examined its members morphologically and phylogenetically. We obtained phylogenetic relationships by Bayesian inference and maximum likelihood analyses of internal transcribed spacer (ITS) and rps16 intron gene sequences. We also examined pollen ornamentation and seed surface sculpturing with scanning electron microscopy. We found that, while F. subpinnata is a member of the tribe Pyramidoptereae, F. gracillima is a member of the tribe Selineae, and this conclusion was supported by our analyses of both the ITS and rps16 intron sequences. When we evaluated all of our results together, we deduced that F. gracillima should be removed from Froriepia. Ultimately, in light of both differences in morphological characteristics and phylogenetic evidence, we describe a new genus, Yildirimlia. The taxonomical diagnosis, detailed description, and illustrations of the new genus are provided herein.

Berberocarum (Apiaceae), a new genus from the High Atlas Mountains (Morocco), with notes on some other NW African Umbelliferae–Apioideae

“…The conflict between the results regards the position of tribe Careae, which is resolved as sister to tribe Pyramidoptereae in the ITS tree, but is nested into it in the rps16 tree. This result is congruent with that inferred by a recent study using rps16 sequences (Doğru‐Koca et al 2020) based on a smaller data set. It should be noted, however, that the overall resolution and branch support in the rps16 tree is much lower than in the ITS tree because of lower variability of the plastid sequences.…”

“…According to a BLAST search in the GenBank database (<http://www.ncbi.nlm.nih.gov>), Carum atlanticum demonstrate affinity within the tribe Pyramidoptereae, whereas C. proliferum , C. jahandiezii and C. lacuum fall within the tribe Apieae. To determine more precisely the phylogenetic position of the studied species, the published nrITS datasets from Zakharova et al (2012), Fernández Prieto and Cires (2014), Jiménez‐Mejías and Vargas (2015) and Doğru‐Koca et al (2020) were modified and used. The final set of samples was increased to include representatives of the tribe Careae, which comprises the generitype Carum carvi , and the Conioselinum chinense Clade, which includes Meum athamanticum connected with Carum atlanticum in its taxonomic history.…”

Plastid Phylogenomic Analysis of Tordylieae Tribe (Apiaceae, Apioideae)

“…Individual plastid markers (intron sequences of rps16 , rpl16 , rpoC1 genes) often did not show sufficient variability to provide resolution both within the Tordylieae and between the adjacent tribes or produced trees incongruent with the nrITS phylogeny [ 35 , 49 , 50 ]. A recent plastid phylogenomic investigation claimed new robust evidence for incongruence between the nuclear genome and plastome evolution in Tordylieae [ 20 , 26 ].…”

Synecology of Lagoecia cuminoides L. in Italy and evaluation of functional compounds presence in its water or hydroalcoholic extracts

“…and Oedibasis Koso-Pol., with an outside position from all other Saniculoideae . Finally, Doğru-Koca et al 41 from a phylogenetic point of view suggested that Froriepia K.Koch should be the sister genus of Lagoecia cuminoides , and although both genera belong to the same tribe ( Piramidoptereae ), they are morphologically very different from each other. Even if the collocation of the genus Lagoecia is complex, from a morpho-taxonomic point of view Lagoecia should be considered very close to Petagnia , having in common a specific character: the abortion of an ovarian lodge 21 and the consequent maturation of a single achene.…”
