“…Genetic diversity is of fundamental importance in the continuity of a species as it provides the necessary adaptation to the prevailing biotic and abiotic Table 1) Genet Resour Crop Evol environmental conditions, and enables change in the genetic composition to cope with changes in the environment (Ç alişkan 2012; Sheidai et al 2013Sheidai et al , 2014a. In general we found low degree of genetic diversity in all four studied Linum species.…”

The genus Linum L. (Linaceae) has more than 200 species. These species have agricultural, industrial, and medicinal importance. Domestication and continuous selection reduce genetic diversity of plants and in order to develop new and improved varieties, we should utilize all available genetic diversity in that crop and its wild relatives. The cultivated flax (L. usitatissimum L.) is an important crop plant and is being evaluated as a crop platform for the production of bio-industrial and nutraceutical products. In present study, we studied 230 plants of 23 populations in four Linum species namely, pale flax (L. bienne Mill.), cultivated flax (L. usitatissimum L.), and two wild relatives, L. austriacum L. and L. album L. The objective of this study was to investigate population genetic structure and genetic variability within each species using SSR and EST-SSR markers.The low degree of genetic variability was obtained in these species. AMOVA revealed significant genetic difference among species and populations. The significant correlation was observed between genetic and geographical distances the studied species. Evanno test and K-Means clustering revealed genetic fragmentation in the studied Linum species. Networking and STRUCTURE analysis revealed genetic affinity of the populations. The population assignment test revealed absence of gene flow or the occurrence of very limited gene flow among populations.

“…The issue of monophyly needs to be assessed critically in all molecular-based phylogenetic studies, especially when considering the weight currently being placed on phylogenies and the consequent implications for evolution, ecology, biogeography and more importantly taxonomic adjustments (Ramdhani et al 2011). Nuclear molecular technique has been successfully used for investigation of infraspecific variations in different genera (Sheidai et al 2014Koohdar et al 2016). Therefore, we decided to use the molecular approach for investigation of infraspecific variations between Sambucus species.…”

Sambucus is a medicinal plant with approximately 25 accepted taxa in the world from which two are present in Iran, S. nigra and S. ebulus. In order to evaluate the affinities and relationships in Sambucus and resurrect subspecies or verities in these two species, the micro-morphological, anatomical and molecular properties of Sambucus species of Iran have been studied. Pollen and seed surfaces of two species were examined with scanning electron microscope. In micro-morphological studies, the pollen shape is prolate-spheroidal in S. nigra but subprolate in S. ebulus. The exine sculpture is microperforate in S. nigra and is reticulate-microechinate in S. ebulus. The surface of the seed in S. nigra is smooth, not elongated and no clear organizational pattern is discernable and the anticlinal walls are shallowly undulate. In S. ebulus, the seeds have a microperforate surface and the anticlinal walls are observed deeply undulate. Petiole anatomical studies show that vascular bundles and existence of druse crystals are diagnostic characters in studied species. Using nuclear (nrDNA ITS) marker, we reconstructed phylogenetic relationships within two species of Sambucus. The ITS dataset was analyzed by phylogenetic methods including Bayesian inference, maximum likelihood and maximum parsimony. In phylogenetic analyses, all members of this genus form a well-supported clade (PP = 1, ML/BS = 100/100). The Sambucus clade is composed of two clades. Clade I includes the populations of S. nigra and the clade II comprises the rest of the species of Sambucus (S. ebulus). NeighborNet diagram demonstrated separation of the studied populations. In general, molecular studies supported micro-morphological findings. Pollen, seed-coat characters and molecular phylogeny support the separation of S. nigra and S. ebulus .

“…We used MDS plot for grouping of the plant populations. AMOVA (Analysis of molecular variance) test (with 1000 permutations) as implemented in GenAlex 6.4 (Peakall, Smouse, 2006), and Nei ' s Gst analysis of GenoDive ver.2 (2013) (Meirmans , Van Tienderen, 2004), were used to reveal significant genetic difference among the studied populations (Sheidai et al, 2014). GST = − (Ht is heterozygosity over all populations, Hs is mean heterozygosity within the populations (Hedrick, 2005).…”

“…Molecular methods for characterizing genetic diversity developed enormously and techniques such as ISSRs, microsatellites or AFLPs, have been extensively applied particularly to geographically differentiated populations Sheidai et al, 2014;Koohdar et al, 2015,). Nevertheless, at this level, collecting strategies in wild species is still a matter of determining the size of the sample per site (population/ subpopulation) and the number of sites that need to be sampled to ensure appropriate allelic retention.…”

Lallemantia is a small genus with 5 species, which one of them is Lallemantia peltata. This aromatic plant grows in a limited area of the Iran and is known as medicinal herb in folk medicine. We have no information on the infraspecific variations on morphological, anatomical and molecular features of this species. Therefore, in the current study; we investigated these variations on six geographical populations of it. These plants were used for morphological, anatomical and molecular investigations. GenAlex, GenoDive and PAST softwares were used for statistical analyses. In morphological study, we used fifteen characteristics. PCA bi-plot revealed some characteristics had diagnostic value in separation of the populations. The studied populations were clustered into two groups. We examined fifteen qualitative and quantitative anatomical variables. PCA loading revealed that some anatomical variables had the highest positive correlation and were the most variable anatomical characters among the studied populations. Based on the anatomical traits, theses populations divided into two groups. Ten ISSR primers were used for examination of genetic variations among the populations. The STRUCTURE analyses of ISSR data revealed two groups in theses populations that they were divided into two groups in MDS plot. The results of morphological, anatomical and also ISSR studies were similar. Clustering and ordination of the studied populations separated some of these populations from the others and suggest the existence of two groups within this species.
