To obtain greater insight into the molecular events underlying plant disease susceptibility, we studied transcriptome changes induced by a host-selective toxin of Pyrenophora tritici-repentis, Ptr ToxA (ToxA), on its host plant, wheat. Transcriptional profiling of ToxA-treated leaves of a ToxA-sensitive wheat cultivar was performed using the GeneChip Wheat Genome Array. An improved and up-to-da...

The wheat proteins soluble in chloroform-methanol mixtures are associated with several kinds of food allergies. A separation method based on capillary zone electrophoresis (CZE) with UV detection was developed for the analysis of these mixtures. An acidic phosphoric acid/β-alanine (pH 2.5) buffer containing HPMC, urea and acetonitrile was used for the separation. The capillary electrophoresis (...

A n n u a l W h e a t N e w s l e t t e r V o l. 5 8. Our organic breeding program is highly focused on the development of new, organic cultivars of alternative or underutilized cereals such as einkorn and emmer. A new, organically bred, einkorn cultivar, Mv Menket, was released last year. This is the first semidwarf einkorn cultivar in the market, with elevated yield potential, and excellent r...

durum wheat due to its quality is an important crop in feeding and economics. saji is a newly released durum wheat cultivar with a mean yield of 2824 kgha-1 which was higher than the two durum wheat (zardak) and bread wheat (sardari) check cultivars in different yield traits conducted during 2000-2008 cropping seasons in iran. its grain yield was 23% and 11% higher than those of zardak and sard...

Effect of five NaCl salinity treatments (0, 50, 100, 200 and 300 mM) given at different growth and developmental stages on total N level and in vitro nitrate reductase activity (NRA) in leaves and roots of two wheat cultivars viz., Ghods and Boolani was studied in greenhouse conditions. In response to salinity treatments, total N concentrations and NO3 assimilation rates in Ghods, a saltsensiti...

samanoo is a traditional iranian dessert that has a high nutritional value. its consumption is on the rise.samanoo is made using a mixture of wheat sprout extract (wheat malt) and whole wheat flour. it is mainlyprepared at home or at in small businesses and there is no standard method of preparation. this studyinvestigates the effects of wheat cultivar (hirmand and tabasi) and the ratio of whea...

Carotenoid content is a primary determinant of wheat nutritional value and affects its end-use quality. Wheat grains contain very low carotenoid levels and trace amounts of provitamin A content. In order to enrich the carotenoid content in wheat grains, the bacterial phytoene synthase gene (CrtB) and carotene desaturase gene (CrtI) were transformed into the common wheat cultivar Bobwhite. Expre...

In order to study planting date impacts and ending season drought stress  on grain yield and  gaining weight  rate  and wheat filling period characteristics in new advanced bread wheat genotypes ,this research  is done by using plan statistical  of spilt plot  in form of complete random blocks basic  plot with 3 replications in both common separated irrigation  and ending season drought  stress...

Wheat (Triticum aestivum L.) plants change their metabolic state in response to low non-freezing temperatures adjusting the cellular homeostasis for upcoming winter season. The induction of oxidative stress during cold hardening as well as in response to freezing stress and recovery was under investigation in this work. Here we present data about the performance of some enzymes involved in plan...

Extremely short, high yielding cultivars of all crop plants are needed to optimize the food production of bioregenerative life support systems in space. In the early 1980's, we examined over a thousand wheat genotypes from the world germplasm collection in search of genotypes with appropriate characteristics for food production in space. Here we report the results of 12 years of hybridization a...
