the genus onobrychis is an important forage crop consisting of approximately 130 annual and perennial species. in this study, 13 populations of five onobrychis species were analyzed. the basic chromosome number varied from x=7 to x=8. according to stebbins’ classification, populations such as o. aucheri subsp. psammophila, o. crista-galli (1) and o. crista-galli (2) were classified in symmetric...
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...
in this study the original mitotic chromosome counts are presented for 5 onobrychis species of o. sect. onobrychis in iran, 2n = 2x = 14 for o. persica, 2n = 4x = 28 for o. viciifolia, 2n = 4x = 28 for o. altissima, 2n = 2x = 14 for o. shahpurensis and 2n = 2x = 14 for o. sosnovskyi. the basic chromosome numbers of all studied taxa are consistent with the proposed base number of x = 7. in addit...

Animal societies exhibit remarkable variation in their breeding strategies. Individuals can maximize their fitness by either reproducing or by helping relatives. Social hymenopterans have been key taxa for the study of Hamilton's inclusive fitness theory because the haplodiploid sex-determination system results in asymmetric relatedness among breeders producing conflict over the partitioning of...
Onosma L. as a rich taxa in Boraginaceae including about 150–180 species, centered mainly in Irano-Turanian region. The genus faced with several systematic complexities lead to many identification problems as well as morphological polymorphism. Several authors have used setae characteristics in Onosma as the most important diagnostic evidence in delimitation and classification of species in add...

The genus Ononis,embraces more than 85 species worldwide. In the present study, materials of two subspecies of O. spinosa from different localities of Iran alongside some other native species of the genus were included in phylogenetic analyses. In addition, over 50 accessions were obtained from GenBank. In order to clarify the exact number of subspecies of O. spinosa in Iran, datasets were obta...
