background: in current study, chemical composition and antibacterial activity of leaves and flowers essential oils of origanum vulgare ssp. gracile against four food-borne pathogens including escherichia coli, listeria monocytogenes, salmonella thyphimurium and staphylococcus aureus were examined. methods: the different organs (leaves and flowers) of o. vulgare ssp. gracile were harvested at f...
مرزنجوش (origanum vulgare l.) گیاهی از خانواده نعناع و بومی ایران می باشد. این گیاه علاوه بر استفاده در طب سنتی به عنوان داروی مسکن، مدر، معرق و ضد عفونی کننده، در درمان بیماری های مربوط به معده و روده و همچنین یبوست کاربرد فراوانی دارد. گونه های جنس مرزنجوش به طور گسترده ای در صنعت ادویه مورد استفاده قرار می گیرند. در این مطالعه، پیکره ی رویشی یک زیرگونه از این گیاه (origanum vulgare ssp. vulg...
Increased seed production has been a common goal during the domestication of cereal crops, and early cultivators of barley (Hordeum vulgare ssp. vulgare) selected a phenotype with a six-rowed spike that stably produced three times the usual grain number. This improved yield established barley as a founder crop for the Near Eastern Neolithic civilization. The barley spike has one central and two...
A dosage effect of chromosome 5A (formerly IX) of common wheat, Triticum aestivum L. emend Thell. ssp. vulgare, has been well established. With increasing dosage from monosomic to tetrasomic, the phenotype changes from speltoid to normal vulgare type (squarehead) to subcompactoid to compactoid (HUSKINS 1946; SEARS 1952, 1954) (Figure 1 and Table 3) . This is due to the pleiotropic gene Q locate...
Nitrogen Composition during Vegetative and Generative Growth Stages of Two Origanum Taxa from Turkey
Origanum onites and Origanum vulgare ssp. hirtum were collected from Balikesir, on the north west of Turkey. The nitrogen contents in organs such as root, stem, leaf and flower of Origanum onites and Origanum vulgare ssp. hirtum taxa in vegetative and generative growth stages were investigated. Nitrogen analyses of soil and plant samples were carried out according to the Kjeldahl method. It was...
Chloroplast DNA (cpDNA) diversity was found within and among populations (245 accessions total) of wild barley, Hordeum vulgare L. ssp. spontaneum Koch from Israel and Iran. Three polymorphic restriction sites (HindIII, EcoRI, BclI) which define three distinct cpDNA lineages were detected. One lineage is common to populations in the Hule Valley and Kinneret of northern Israel, and in Iran. The ...
The wild ancestral form of barley, Hordeum vulgare ssp. spontaneum, is a valuable source for gene enrichment of cultivated barley. The purpose of this work was to study the area of distribution as well as the extent and structure of genetic variation of wild barley populations grown in Kazakhstan. It was found that distribution of wild barley populations in Kazakhstan is restricted to the most ...
Genetically well-characterized mapping populations are a key tool for rapid and precise localization of quantitative trait loci (QTL) and subsequent identification of the underlying genes. In this study, a set of 73 introgression lines (S42ILs) originating from a cross between the spring barley cultivar Scarlett (Hordeum vulgare ssp. vulgare) and the wild barley accession ISR42-8 (H. v. ssp. sp...
The evaluation of both the genetic variation and the identification of salinity tolerant accessions of Tibetan annual wild barley (hereafter referred to as Tibetan barley) (Hordeum vulgare L. ssp. Spontaneum and H. vulgare L. ssp. agriocrithum) are essential for discovering and exploiting novel alleles involved in salinity tolerance. In this study, we examined tissue dry biomass and the Na(+) a...
