Molecular appraisal ofBuniumand some related arid and subarid geophilic Apiaceae-Apioideae taxa of the Ancient Mediterranean

Abstract

Bunium is unusual in Apiaceae in having a variable cotyledon number and broad infrageneric dysploidy. To test the monophyly of the genus, phylogenetic relationships among 39 Bunium species were investigated with DNA sequence data from nuclear (nrITS) and plastid (psbA-trnH intergenic spacer) regions. Several other taxa with a similar ecology and geography were also included in the analyses. Our results suggest that Bunium is not monophyletic. Bunium spp. in the eastern part of the study area are more closely related to the Central Asian genera Elaeosticta, Galagania, Hyalolaena, Mogoltavia and Oedibasis than to those in the western part. Our study revealed that molecular, morphological (cotyledon number and width of fruit commissure) and karyological data reveal similar patterns in the taxa studied.

Redefined generic limits ofCarum (Umbelliferae, Apioideae)and new systematic placement of some of its taxa

“…this confirms in a much more detailed way the preliminary findings in previous molecular phylogenetic analyses including members of Carum (Papini 2006, Degtjareva & al. 2009).…”

“…c. B. clarke) had been demonstrated to be morphologically alien to Carum; of these C. diversifolium was shown to be member of Trachyspermum link. also molecular phylogenetic studies by Papini (2006), and Degtjareva & al. (2009) indicated that Carum is polyphyletic, although their samplings usually included only few species of the genus.…”

“…in the light of the apparent polyphyly of Carum, the initial set of samples was increased, based on previous studies (Papini 2006;Spalik & Downie 2007;Degtjareva & al. 2009;Magee & al.…”

A taxonomic study of the genus Hellenocarum H.Wolff (Umbelliferae-Apioideae)based on morphology, fruit anatomy, and molecular data

“…ETS sequences were generated for 45 of these same accessions (data for Postiella capillifolia could not be obtained despite repeated attempts). PsbA-trnH sequences for 10 species were also newly generated for this study and added to a matrix containing 36 previously published sequences (Degtjareva et al, 2009). Physospermum cornubiense (L.) DC.…”

The genus Elwendia Boiss. (Apiaceae) in the flora of Uzbekistan

“…Род Elwendia восстановлен как самостоятель-ный по отношению к Bunium L. с использовани-ем анатомо-морфологического, ботанико-геогра-фического и кариологического методов исследо-вания (Vasil'eva et al, 1985;Kljuykov, 1988), а также анализа молекулярных данных (Degtjareva et al, 2009(Degtjareva et al, , 2013. От рода Bunium он отличается широкой комиссурой плода, двусемядольными (но не односемядольными) проростками, геогра-фическим распространением и хромосомными числами.…”
