BACKGROUND AND AIMS The diploid goat grass Aegilops tauschii (2n = 2x = 14) is native to the Middle East and is the D-genome donor to hexaploid bread wheat. The aim of this study was to measure the diversity of different subspecies and varieties of wild Ae. tauschii collected across the major areas where it grows in Iran and to examine patterns of diversity(More)
Some plants growing on serpentine (ultramafic) soils are able to hyperaccumulate nickel in their above-ground parts. The genus Alyssum L. contains the greatest number of Ni-hyperaccumulator plants so far reported. There are substantial areas of serpentine soils at many locations in Iran. This paper presents the analyses for Ni, Cr, Mn, Fe, Mg and Ca in(More)
Microsatellite markers were used to analyse the biodiversity of 57 accessions of different subspecies and varieties of wild Aegilops tauschii (2n = 2x = 14; D genome) collected across the major areas where it grows in Iran. Levels of diversity were high, with numbers of alleles averaging 7.3 (ranging up to 12) and polymorphism information contents averaging(More)
Cereal species of the grass tribe Triticeae are economically important and provide staple food for large parts of the human population. The Fertile Crescent of Southwest Asia harbors high genetic and morphological diversity of these species. In this study, we analyzed genetic diversity and phylogenetic relationships among D genome-bearing species of the(More)
To evaluate the chemotaxonomic significance of the essential oils of 23 populations of 18 Iranian Ferula species, the chemical composition of the oils was investigated by GC/FID and GC/MS. Altogether, 84 constituents, representing 81.3-99.7% of the total composition of the oils, have been identified. The composition of six species of the genus, i.e., F.(More)
The flavonoid chemistry of 16 species of Chenopodium was investigated, with an emphasis on C. album and its relatives. The chief compounds seen were 3-O-glycosides of quercetin, kaempferol and isorhamnetin. The latter two classes show a mutually exclusive distribution among the diploid and all but one tetraploid species. C. polyspermum is unusual in(More)
Microsatellite markers were used to analyse the genetic diversity of 120 individuals of 20 weedy/wild populations of Secale cereale collected all around Iran. High levels of diversity, with an average number of seven alleles per locus (ranging up to 11) and high level polymorphism with polymorphism rate averaging 0.645 (between populations) and 0.364(More)
The diploid goatgrass Aegilops tauschii is considered the D-genome donor of bread wheat and has probably a centre of diversity in north of Iran. In order to measure the genetic diversity of and the relationships among different populations, varieties and subspecies belonging to Ae. tauschii in Iran, DNA was extracted from 48 accessions of Ae. tauschii(More)
The mountain rye Secale strictum is native to the Middle East and is the progenitor of the cultivated rye. Regarding lack of information about the genetic diversity of this species in Iran, this study was aimed to evaluate its genetic variation and to examine the patterns of diversity related to the varieties and geography. Fifteen wheat and rye derived(More)
The relationships among 55 wheat accessions (47 accessions collected from Iran and eight accessions provided by the Institute of Plant Biology of the University of Zurich, Switzerland) belonging to eight species carrying A genome (Triticum monococcum L., T. boeoticum Boiss., T. urartu Tumanian ex Gandilyan, T. durum Desf., T. turgidum L., T. dicoccum(More)
