In this study, changes in cell wall uronic acid concentrations of boron (B)-tolerant and B-sensitive cultivars; of wheat and barley were analyzed in control (plants that were grown on water and received no B) and B-treated plants. Ten-day-old seedlings of wheat (Triticum aestivum L. 'Atay' (B-sensitive) and 'Bolal' (B-tolerant)) and barley (Hordeum vulgare L. 'Hamidiye' (B-sensitive) and 'Anadolu' (B-tolerant)) were grown in H3BO3 solution (10 mM final concentration) or water for 3, 5, or 7 days. For determination of changes in cell wall uronic acid concentrations of wheat and barley cultivars, cell walls were extracted from root and leaf tissues of control and B-treated plants. Cell wall uronic acid concentrations of root and leaf tissues of each cultivar were statistically analyzed. Various reciprocal analyses were performed. These analyses were high-B-tolerant versus B-sensitive cultivars and control versus B-treated plants. In all reciprocal analyses, no significant changes were observed. These data, thus, suggest that cell wall uronic acid content does not contribute to detoxification of excess B in wheat and barley.

In vitro culture offers approaches to study cellular responses and to obtain cells tolerant to high temperature stress. The objectives of this study were to select wheat cells that tolerate high temperature stress, study cell line stability and cytogenetic characteristics, and compare protein synthesis in selected and control cell lines after exposure to heat stress. Three of 600 colonies plated were recovered after cells had been exposed to 48-degrees-C. Forty-five percent of the cells of the tolerant cell...
Effect of salt stress on antioxidant defense systems of sensitive and resistance cultivars of lentil(Lens culinaris M.)
Cicerali, Işın Nur; Yücel, Ayşe Meral; Department of Biotechnology (2004)
In this study, two lentil cultivars (Lens culinaris, Medik.) (ILL5582-salt tolerant and ILL590) were characterized and compared due to their NaCl susceptibility and antioxidant mechanism was examined under laboratory conditions. Physiological parameters such as wet-dry weight, root-shoot lengths, cell membrane stability, lipid peroxidation in terms of malondialdehyde (MDA), H2O2, proline contents were determined. The activities of antioxidant enzymes such as superoxide dismutase (SOD: EC, catalase...
Ionic liquid pretreatment allows utilization of high substrate loadings in enzymatic hydrolysis of biomass to produce ethanol from cotton stalks
Haykir, Nazife Isik; Bakir, Ufuk (Elsevier BV, 2013-11-01)
To enhance the enzymatic conversion of cotton stalks to glucose at high substrate loadings and subsequently to produce ethanol, biomass was subjected to ionic liquid and alkaline pretreatments. Ionic liquid, 1-ethyl-3-methylimidazolium acetate (EMIMAc), which reduced biomass crystallinity, was effective in improving the conversion of cotton stalks to glucose (82-85%) regardless of the substrate loading used during enzymatic hydrolysis. On the other hand, the glucose yield decreased from 67% to 55% with an i...

Combination of elemental and protein studies along with molecular data using microsatellite markers may lead CO the better and realistic determination of relatedness between the varieties and their populations. In this study, the extent of diversity among five Turkish durum wheat cultivars and their populations has been assessed using seven microsatellite markers and the elemental analysis together with the differences in their protein content. In molecular analysis, total 23 alleles have been obtained amon...
Micromeria myrtifolia: The influence of the extracting solvents on phenolic composition and biological activity
Sarikurkcu, Cengiz; Hanine, Hafida; Sarikurkcu, Rabia Busra; Sarikurkcu, Rifat Tayyib; Amarowicz, Ryszard (Elsevier BV, 2020-03-01)
Currently, there is much interest in using the active compounds that exist in plants as natural treatments. The pharmaceutical industry is also looking for novel chemical compounds from natural sources that do not have side effects. The purpose of this study was to identify the antioxidant and enzymatic inhibition activities of different extracts (ethyl acetate, methanol and water) of Micromeria myrtifolia from Turkey. The phenolic constituents in the extracts were also identified using liquid chromatograph...
