Turkish Journal of Agriculture and Forestry
Downy mildew is a fungal disease caused by Plasmopara halstedii and leads to loss of yield up to 100% in sunflower. Disease control is performed mostly through chemical seed treatment and breeding. Due to the time consuming nature of conventional breeding, it is supported by biotechnological approaches. Marker-assisted selection (MAS) is a strategic approach in molecular breeding using molecular markers. Single nucleotide polymorphisms (SNPs) such as insertions, deletions, and base-pair substitutions are more advantageous than other molecular markers. The abundance and biallelic nature of SNPs in a genome provide flexibility in the choosing of SNPs at the desired loci. Competitive …

Characterization Of The Beta1 Gene, Which Might Play A Role In Beta Vulgaris Subsp. Maritima Salt Tolerance, Özge Uysal, Çi̇ğdem Çakiroğlu, Ahmet Koç, Hüseyi̇n Çağlar Karakaya
Turkish Journal of Botany
Salinity stress has a negative impact on plant growth, which affects homeostasis and productivity. The uptake of nonessential salt ions changes the osmotic balance of the cell and causes dehydration. Higher plants develop salt tolerance mechanisms to avoid dehydration. Sea beet (Beta vulgaris subsp. maritima) is a halophytic ancestor of cultivated sugar beet that displays salt stress tolerance. In this study, we screened a B. vulgaris subsp. maritima cDNA library in Saccharomyces cerevisiae strain Ab11c (ena1Δ, nha1/4Δ, nhx1Δ), which is deficient in sodium transport, to find sodium-detoxifying genes. We identified a cDNA construct, named BETA1, providing salt tolerance to yeast …

Highly Selective Schiff Base Derivatives For Colorimetric Detection Of Al$^{3+}$, Zi̇ya Aydin, Mustafa Keleş
Turkish Journal of Chemistry
Schiff base derivatives NBAR and NSAR were developed for selective detection of Al$^{3+}$ in aqueous solution. UV-vis spectroscopic studies revealed that NBAR and NSAR showed marked sensitivity and selectivity to Al$^{3+}$ in acetonitrile (ACN)/water (v/v, 1:1, pH 6.80). The NBAR and NSAR receptors bound Al$^{3+}$ in a 2:1 stoichiometry with apparent binding constants 4.09 $\times $ 10$^{11}$ M$^{-2}$ and 1.65 $\times $ 10$^{12}$ M$^{-2}$, respectively. They also displayed distinct changes in color upon the alteration of free Al$^{3+}$ levels in solution with reversible responses and showed little interference with other metal ions.

Evolution Equations With A Parameter And Application To Transport-Convection Differential Equations, Emile Franc Doungmo Goufo
Turkish Journal of Mathematics
We deeply investigate the well-posedness of models taking the form $_0^AD^{\beta }_tu(t) = Au(t),\;\; u(0)= \,f,\;\;\;00$ where $_0^AD^{\beta }_t$ is a derivative with the fractional parameter $\beta$ and $A$ is a closed densely defined operator in a Banach space. We show that, unlike other systems, solutions of our models are not governed by Mittag--Leffler functions and their variants. We extend and adapt Peano's idea to our models and establish conditions for existence and uniqueness of solutions. In particular, relations between the two-parameter solution operator, its resolvent, and its generator are provided; the issue of subordination and prolongation principles are addressed; …

Selectivity indexes (SIs) were expressed as IC$_{50}$ (MAO-A) / IC$_{50}$ (MAO-B). Compound 3f showed promising $h$MAO-A inhibition with an IC$_{50}$ value of 1.20 $\mu $M and displayed a very significant SI of 0.04 towards $h$MAO-A. The mechanism of $h$MAO-A inhibition was investigated by enzyme kinetics using Lineweaver--Burk graphics. Compound 3f was further screened for its cytotoxicity by using a healthy NIH/3T3 mouse embryonic fibroblast cell line (ATCC CRL1658) and was evaluated as nontoxic at its effective …

A new species of the Mesobiotus harmsworthi group is described from Ethiopia. An integrative taxonomy approach was applied by combining morphological and morphometric analyses-imaging under phase contrast and scanning electron microscopy with molecular analysis (18S rRNA, 28S rRNA and COI markers)-to cross-verify the status of the population as a new species. The specimens of Mesobiotus ethiopicus sp. nov. are most similar to two taxa of the harmsworthi complex: M. harmsworthi obscurus (Dastych, 1985) and M. peterseni (Maucci, 1991). Nevertheless, the new species can be easily distinguished from the first of these taxa by the absence of additional teeth in the …

The immune system is not only evolved to protect the body from pathogens, but it also recognizes and eliminates cancer cells. CD4+ helper T (Th) lymphocytes are central intercessors differentiated according to the character of physiological or pathological status. Generation of type 1 Th (Th1) cells is primarily associated with a pathological insult that must be removed through immune elimination. Upon interacting with other immune and transformed cells, Th1 cells can hamper cancer progression. Therefore, it is a major obstacle for tumor cells to become insensitive or resistant to Th1-oriented actions. The organism employs various mechanisms to return to a …
