orf256 is a wheat mitochondrial gene associated with cytoplasmic male sterility (CMS) that has different organization in various species. This study exploited the orf256 gene as a mitochondrial DNA marker to study the genetic fingerprint of Triticum and Aegilops species. PCR followed by sequencing of common parts of the orf256 gene were employed to determine the fingerprint and molecular evolut...
مرگ سلولی برنامه ریزی شده یا اپوپتوزیس بعنوان یک فرآیند مهم دخیل در رشد و نمو گیاهان در نظر گرفته شده است که ممکن است توسط تنش های زیستی و غیر زیستی از جمله تنش شوری القاء شود. ویژگی های مشخصه اپوپتوزیس شامل قطعه قطعه شدن dna ، تغییر مورفولوژی هسته و ظهور اجسام اپوپتوتیک می باشد. تنش شوری یکی از جدی ترین مشکلات کشاورزی در مناطق خشک و نیمه خشک محسوب می شود. در این مطالعه به بررسی مرگ سلولی القا...
effect of static magnetic field (smf) on plants is a matter of debate. in the present study plausible useful effects of smf on wheat plant (triticum aestivum l.) via improvement of antioxidant system and iron/ferritin fortification were evaluated. the plants were cultivated in pots and in their reproductive stages were treated with or without a 30 mt smf for 4 days, each 5h. the activity of ant...
the objective of this study was to estimate genetic parameters and to investigate the type of gene action in controlling androgenesis in wheat. two wheat cultivars of grebe and houtman were reciprocally crossed with two synthetic genotypes of do1 and pol and then a complete set of the parents, f1, reciprocal f1 (rf1), f2 and back-cross generations (bc1 and bc2) of each cross were used for anthe...
Using Roche/454 technology, we sequenced the chloroplast genomes of 12 Triticeae species, including bread wheat, barley and rye, as well as the diploid progenitors and relatives of bread wheat Triticum urartu, Aegilops speltoides and Ae. tauschii. Two wild tetraploid taxa, Ae. cylindrica and Ae. geniculata, were also included. Additionally, we incorporated wild Einkorn wheat Triticum boeoticum ...
Hulled wheats are neglected crops that have potential in plant breeding programmes of modern durum and common wheat. Among these wheats, three species were widely cultivated in Spain until the mid 20th century: Triticum monococcum ssp. monococcum (einkorn), Triticum turgidum ssp. dicoccum (emmer) and Triticum aestivum ssp. spelta (spelt). One important aspect of wheat grain quality is starch co...
Wheat of both the tetraploid (Triticum durum Desf.) and hexaploid (Triticum aestivum L.), is the most important cereal crop in Ethiopia, ranking third in total production (17%) next to maize (Zea mays L.) and tef (CSA, 2002). Wheat covers a total arable land of 110,434 ha with average productivity of about 8.4 qt ha-1, which is below the national average (14.4 qt ha-1). A field experiment was c...
The Hardness (Ha) locus controls grain hardness in hexaploid wheat (Triticum aestivum) and its relatives (Triticum and Aegilops species) and represents a classical example of a trait whose variation arose from gene loss after polyploidization. In this study, we investigated the molecular basis of the evolutionary events observed at this locus by comparing corresponding sequences of diploid, ter...
Aims: The clinical effects of a Triticum vulgare-containing mouth gel on oral mucositis were evaluated. Presentation of Cases: Five children suffering from oral mucositis due to chemo/radiotherapy were treated with a Triticum vulgare-containing mouth gel, spreaded three times in a day as thin layer on the mucosal lesions for 14 days. Control visits were conducted at the days 4th, 7th and 14th. ...
Wheat bugs are widely distributed in various areas of Europe, Asia and North Africa. Species belonging to the genus Eurygaster and Aelia pierce wheat kernels affecting protein quality. The effects of these insects’ feeding activity have been studied mainly in bread wheat (Triticum aestivum L.). This study provides information on the degradation of prolamin proteins (glutenins and gliadins) of b...
