Background: A total of 150 bread wheat genotypes representing 121 Indian and 29 Turkish origin were screened for nutrient concentrations and grain protein content. Elemental and grain protein composition were studied by Inductively Coupled Plasma-Atomic Emission Spectrophotometer and LECO analyser, respectively. The study was performed to determine the variability in nutrient concentrations present in the collected wheat genetic material from two countries. Results: Several fold variations among genotypes existed for almost all the elements. Three major components of principal component analysis (PCA) revealed 60.8% variation among the genotypes. Nutrient variables segregated into two groups, one group containing all the macroelements except sulphur; and another cluster containing proteins and all the microelements except Zn and Mn. Pearson correlation analysis and heat-map were in accordance with each other determining strong positive association between P-K, Mn-Zn, Mg-S and Cu-protein content. Also, PCA and hierarchical grouping divided all the Indian and Turkish genotypes in two main clusters. Conclusions: Nutritional profile differentiated the genotypes from two countries into separate groups. However, some of the varieties were closely associated and indicated the success of global wheat exchange programs. While most of the correlations were in agreement with the previous studies, non-association of zinc with grain protein content directed towards its control by some other genetic factors. Some of the experimental wheat varieties with promising nutrient content have been suggested for future wheat advancement programs. Results obtained will be supportive for breeders involved in wheat biofortification programs, food industries and people relying on whole grain wheat products.


Assessment of genetic variation of bread wheat varieties using microsatellite markers
Akkaya, Mahinur; Buyukunal-Bal, EB (2004-01-01)
The DNA fingerprinting profiles of 11 bread wheat cultivars, grown in Turkey, was obtained by using 19 highly polymorphic wheat microsatellites. Up to six randomly selected individuals from each of these cultivars were subjected to analysis. Estimated polymorphism information content (PIC) values among 65 individual genotypes for 19 loci were between 0.36 and 0.87 with an average value of 0.68. The numbers of observed alleles were between 2 and 9, with an average value of 5.42. These relationships were asse...
Investigating the roles of micrornas in biotic stress responses and functional characterization of a novel ztl-type f-box protein via virus induced gene silencing
Dağdaş, Yasin Fatih; Akkaya, Mahinur S.; Department of Biotechnology (2009)
Barley and wheat are the two most important crop species in Turkey. Molecular studies for increasing crop yield of these species are very important for the economic benefits of Turkey. Powdery mildew and yellow rust are the two main pathogens, infecting barley and wheat, respectively in our country and causing a great amount of yield loss each year. Till now, classical genetics studies were performed in order to develop resistant barley and wheat cultivars, but these studies have not been succesful. Therefo...
Optimisation of tissue culture, regeneration and Agrobacterium-mediated transformation paramaters in winter wheat cultivars (T.durum cv. Kiziltan-91 and T.aestivum cv. Bezostaja-01)
Kavas, M.; Öktem, Hüseyin Avni; YÜCEL, MUSTAFA (2006-08-18)
Wheat, like other cereal species, shows a common recalcitrance and strong genotypic variation in tissue culture and Agrobacteriummediated transformation. A variety of explant sources have been used for obtaining wheat plants from in vitro cultures and Agrobacterium- mediated transformation. These are: isolated microspores (Mejza et al., 1993), mature embryos (Özgen et al., 1998; Delporte et al., 2001), immature embryos (Ozias-Akins and Vasil, 1982; Vasil et al., 1990; Pellegrineschi et al., 2004), and immat...

Bread wheat (Triticum aestivum) is the most commonly grown crop due to its adaptation in a wide range of ecogeographical conditions and providing enhanced food assurance to the modern world. A diverse and rich collection is the foundation of each successful wheat improvement program. Therefore, major efforts are in progress worldwide to boost wheat production by broadening genetic diversity. Accepting this issue as a target, present study gives an overview of the major progress in the diversity and populati...
Surveillance study of salmonella in fresh peppers (capsicum annuum l.) and inactivation by high hydrostatic pressure treatment

The main objective of this study was to investigate distribution of Salmonella in fresh peppers in Turkey. To serve this purpose, a total of 255 fresh pepper samples (green, kapya, bell, mazamort and charleston) were collected from 3 districts within 9 supermarkets and 3 bazaars in Ankara, Turkey. Salmonella suspected colonies was confirmed by using polymerase chain reaction (PCR) of Salmonella specific gene, invA. One of isolate was assigned as Salmonella, which was isolated from kapya pepper. Confirmed Sa...
