“…A high level of correlation was observed for durum wheat for both the two sites: in particular six couples of elements (Cu/Zn, Mg/Zn with significance at p < 0.001 and Cu/Mg, Cu/Mn, Zn/Mn, Cr/Fe with significance at p < 0.01) for site A and seven couples of elements (K/Cu, K/Mg, K/Mg, Cu/Mg, Cu/Mn, Cr/Fe with significance at p < 0.001 and Ca/Cd with significance at p < 0.01) for site B (Tables 3 and 5), while wild wheat showed a low number of correlations in both the two sites (Cr/Cu, Fe/Mn with significance at p < 0.001 and Cr/Fe, Cr/Mg, Cd/Mn and Ca/Mg with significance at p < 0.01 for site A; Cr/Fe with significance at p < 0.001 and Ca/Cd, K/Zn, K/Cr, K/Fe, Cr/Fe with significance at p < 0.01 for site B, Tables 4 and 6). It should also be noted that in some cases, more significant or positive correlation values for other elements (i.e., Mn/Mg) were expected, although comparable results to those that were obtained in this work were also reported in literature [28,37,47,48]. Multivariate statistical analysis (PCA and OPLS-DA) was used to deeply investigate the variation in macronutrients (Ca, Mg, K), micronutrients (Zn, Fe, Cu, Mn) and toxic trace elements (Cd, Pb) for the whole dataset of 25 wheat accessions and cultivars (three replicates for each cultivar studied) that is representative of durum and wild species in the two cultivation sites.…”

Crop production and natural resource use, especially in developing countries, represents one of the most important food sources for humans. In particular, two wheat species (tetraploid, which is mostly used for pasta and hexaploid, which is primarily used for bread) account for about 20% of the whole calories consumed worldwide. In order to assess the mineral accumulation capability of some popular tetraploid wheat genotypes, a metabolomic (metallomic) approach was used in this study. The metallomic profile related to micro- (Zn, Fe, Cu, Mn, Ni and Cr), macro- (Ca, Mg and K) and toxic trace elements (Cd and Pb) was obtained by ICP-AES analysis in a large set of tetraploid wheat genotypes (Triticum turgidum L.) that were grown in two different experimental fields. Correlations and multivariate statistical analyses were performed, grouping the samples under two wheat sets, comprising cultivated durum cultivars (T. turgidum subsp. durum) and wild accessions (T. turgidum subsp. dicoccum and subsp. dicoccoides). The site dependence ranking for the selected genotypes with the highest nutrient accumulation was obtained. The significantly higher content of Mg (among the macronutrients) and the highest levels of Mn, Fe and Zn (among the micronutrients) were found for wild accessions with respect to durum cultivars. Moreover, the former genotypes were also the ones with the lowest level of accumulation of the trace toxic elements, in particular Cd. According to the performed statistical analyses, the wild accessions appeared also to be less influenced by the different environmental conditions. This is in accord with literature data, indicating the superiority of “old” with respect to modern wheat cultivars for mineral content. Although further studies are required on a wider range of genotypes to confirm these findings, the obtained results could be used to better select the less demanding and better performing cultivars in specific target wheat growing environments.

“…Using seven Turkish wheat cultivars and 223 genomic SSR markers, the mean PIC value was found to be 0.522 (Akfırat and Uncuoğlu, 2013). Five Turkish durum wheat varieties were differentiated with seven SSR markers with a relatively high range of PIC values (0.227-0.887) (Hakkı et al, 2014). In our study, the markers derived from different genomes resulted in similar allele numbers, although the B genome markers had the least informative alleles.…”

Turkey is an important bread wheat producer. The objective of this study was to dissect the diversity of genetic, agronomic, and quality characteristics of bread wheat cultivars grown on 25% of the total wheat area in Turkey. A total of 24 wheat cultivars and 5 wild progenitors of wheat were examined using 24 simple sequence repeat (SSR) primers with a known physical locus on the A, B, and D genomes of hexaploid wheat. A total of 72 bands produced 939 alleles on the wheat cultivars and wild progenitors. Markers were efficient in discriminating the species and the highest genetic diversity information was obtained from the markers Xgwm312 and Xgwm372. Microsatellite markers clearly separated cv. Pandas from all other cultivars although it was closely related to most of them in terms of agronomic and quality traits. Four agronomic characteristics including yield component traits and eight bread quality analyses were used for the diversity analyses. A significant association between morphological and bread wheat quality traits was observed while the correlation was weak with the genetic data. Cultivars were also classified with respect to release year and origin. Molecular variance between old (released before the year 2000) and new cultivars accounted for 1% of the total variation and the variance was 3% between national and foreign cultivars. Results showed that the number of alleles was lower in national and new cultivars compared to foreign and old cultivars. Therefore, breeding sources do not appear to improve the genetic base of wheat cultivars in Turkey. Introducing new variation sources may be needed to broaden the narrowed gene pool of bread wheat.

“…Plant samples were mineralized (CEM Mars 5) by heating at 210 °C in a microwave oven and using a high-pressure step (200 PSI). After cooling, the mineralized samples were leached from 1 to 2 µm filter paper (Whatman no: 42) and filled up to 15 mL with ultrapure water in falcon tubes (Hakki et al, 2014). Standard solutions were prepared, and calibration of inductively coupled plasma optical emission spectroscopy was performed using multielement stock solutions of 1000 ppm (Merck).…”

The aim of this research is to evaluate and analyze the influence of different degrees of salt stress on the tolerance of Australian wheat lines having characteristics derived from wild types in comparison with a local cultivar welladapted to Anatolian conditions under controlled conditions. In the research, the two lines, namely AU5924 and AU5907, adapted to Australian conditions harbor HKT1;4 and HKT1;5 loci and Bayraktar 2000 cultivar used as genetic material. In our study, a trial plan with four replicates and two salt treatment doses (0 mM control group and 200 mM stress group) was designed. The samples were collected for elemental analysis, measuring physiological parameters as well as determining proline content after the appearance of stress symptoms. In this respect, (K), known to play an important role in enhancing stress tolerance, was found to be higher in HKT-containing lines in comparison to Bayraktar 2000. HKT genes could improve the production of Anatolian varieties. While the dry weight of the genotype Bayraktar 2000 was higher than the lines checked, the proline content of line 5907 was lower and the potassium and (K/Na) ratio decreased. These parameters effectively increased the dry weight under salt stress. However, the line 5907 demonstrated the best tolerance among all analyzed genotypes.
