Cytotaxonomy of some Onobrychis (Fabaceae) species and populations in Iran

Abstract: A karyological study of 20 taxa (45 populations) of the genus Onobrychis Adans. from different geographic origins is presented. We found the two usual basic chromosome numbers in the genus, x = 7 and x = 8. In the group with x = 7, six diploid (2n = 14), 22 tetraploid (2n = 28) populations and in the group with x = 8, 17 diploid populations were found. Detailed karyotype analysis allows us to group the different populations and to postulate relationships among them.

“…Moreover, Greuteria forms a well-supported large clade with Corethrodendron, Eversmannia and Onobrychis. Species in this clade are mainly distributed in arid areas of centralwestern Asia, the former Tethys area (Shue, 1985;Lock, 2005;He & al., 2006).…”

“…However, these three sections largely correspond to mesic, xeric and psychric habitats, respectively (details see Table 3). According to Shue (1985) and He & al. (2006), Hedysarum may have originated near the Tethys region in the late Eocene to early Oligocene; following the uplift of the Tibet Plateau and the Himalayas, different adaptations evolved and it gradually reached its current distribution range in Asia.…”

“…The root tips were obtained from germinated seeds at 20°C and pre-treatment was performed with αmonobromo naphthalene (0.5%) for 4 hours at 4°C. Root tips were subsequently treated with 10% formaldehyde and 1% chromic acid (1:1) for 16 hours for fixation and were rinsed with distilled water for 3 hours after fixation (Hejazi and Mahdi, 2010). 1N NaOH solution was used for hydrolysing in 60°C between 8 and 12 minutes depending on taxa.…”

“…Cytological and cytotaxonomic information of wild Onobrychis taxa are quite useful in determining the phylogenetic relationships of the taxa (Elci and Sancak, 2009). Hejazi and Mahdi (2010) performed a karyological study of 20 taxa (45 populations) of the genus Onobrychis Adans. from different geographic origins and they found the two usual basic chromosome numbers in the genus, x=7 abd x=8.…”
