Biochemical Diversity and Antioxidant Potential of Wild Chives (Allium Schoenoprasum L.) Accessions
(Academic Press, 2025) Cakmakci, O.; Sensoy, S.; Eroğlu, H.
This study investigated the biochemical diversity of chive (Allium schoenoprasum L.) accessions collected from Van Province, Türkiye, and compared them with selected Allium species (Allium vineale, Allium schoenoprasum var. sibiricum, and Allium tuberosum). The analyses focused on key biochemical traits, including total phenolic content, antioxidant capacity, radical scavenging activity, activities of antioxidant enzymes (superoxide dismutase, catalase, and ascorbate peroxidase), lipid peroxidation, and phenolic compound profiles (quercetin, myricetin, rutin, chlorogenic acid, and quinic acid). Significant biochemical variability was detected among the A. schoenoprasum accessions. Notably, accession A6 exhibited the highest total phenolic content (61.2 g GAE kg-1) and antioxidant capacity (139.89 mmol Trolox equivalents kg-1). Accession A2 showed the greatest superoxide dismutase (24.63 U g-1 FW) and catalase (25.66 U g-1 FW) activities, whereas accession A3 was distinguished by its elevated myricetin concentration. Higher rutin contents were observed in accessions A1 and A2. Hierarchical cluster analysis revealed that A. schoenoprasum accessions formed a distinct cluster, with A. vineale grouping more closely with them than with the other Allium species. Correlation analysis demonstrated strong positive associations between total phenolic content, antioxidant capacity, and individual flavonoid concentrations. Overall, these results highlight the substantial genetic potential of wild A. schoenoprasum accessions from Van Province as valuable genetic resources for Allium breeding programs and as promising natural antioxidant sources for food and pharmaceutical industries. © Articles by the authors; Licensee UASVM and SHST, Cluj-Napoca, Romania.

Effect of Electrospun Nisin and Curcumin Loaded Nanomats on the Microbial Quality, Hardness and Sensory Characteristics of Rainbow Trout Fillet
(Academic Press, 2019) Meral, R.; Alav, A.; Karakas, C.; Dertli, E.; Yilmaz, M.T.; Ceylan, Z.
Nisin and curcumin loaded (NCL) nanomats having 172 nm mean diameter were successfully fabricated. The effect of NCL nanomats in terms of limitation of Total Mesophilic Aerobic (TMAB) and Lactic acid bacteria (LAB) in fish fillets was tested during the analysis period. On the 4th day, while TMAB load of C was 6.61 log CFU g−1, that of the sample coated with NCL nanomats was found to be 3.28 log CFU g−1. TMAB load of control samples reached above 6 log CFU g−1 on the 4th day of cold storage, TMAB load of fish samples coated with nanomats reached the same level up to the 12th day. The shelf life of coated fillets was extended to 12 day. 3–4 logarithmic decrease was obtained in LAB count by NCL nanomats during the analysis period. On the 4th storage day, the hardness value of C sample decreased 21% compared to NCL samples. All sensory attributes of C samples were acceptable by the 4th day of the storage; while sensory attributes of NCL samples were acceptable by the 10th day of storage. The study revealed that nisin and curcumin loaded nanomats could be effectively used to improve the quality of fish fillets. © 2019 Elsevier Ltd
Growth Performance of 'granny Smith' and 'fuji Cultivars Grafted Onto Dwarf Rootstocks: a Preliminary Study in Eastern Anatolia
(Academic Press, 2011) Oǧuz, H.I.; Mtaş, T.; Muradoǧlu, F.
This study was carried out to determine the growth performance of 'Granny Smith' and 'Fuji' apple varieties, which are widley grown in Turkey, grafted to dwarf rootstocks within their initial two years under continental ecological conditions of the Van Region in East Anatolia. In the first year, the vegetative characters of the cultivars were measured, whereas the yield and the growth rate were both determined in the second year. The yields of 'Granny Smith' and 'Fuji' varieties were 2.38 and 3.88 kg, with average fruit weights of 173.71 g and 136.76 g, respectively. The concentrations of soluble solids, an important quality attribute, were 11.2% and 12.9% for 'Granny Smith' and 'Fuji', respectively. Titratable acidity, which indicates the maturity of the fruit and specifies the market suitability, was found to be 0.37% in 'Granny Smith' and 0.52% in 'Fuji'. Although some properties differed between these cultivars, the firmness of both cultivars was the same, with a value of 6.6 libre. Although both varieties have a double sigmoid vegetative growth, 'Granny Smith's vegetative growth was relatively better than that of 'Fuji', whereas 'Fuji' had a higher productivity. However, for precise evaluation of yields, the period of economical production is required. Preliminary results of morphological, phenological, and pomological tests showed that the varieties 'Granny Smith' and 'Fuji' grafted onto dwarf rootstocks have a potential for increased production in the Van region of Eastern Turkey.
New Insights Into Tomato Spotted Wilt Orthotospovirus (Tswv) Infections in Türkiye: Molecular Detection, Phylogenetic Analysis, and in Silico Docking Study
(Academic Press, 2023) Usta, M.; Guller, A.; Demİrel, S.; Korkmaz, G.; Kurt, Z.
Seventy-eight tomato and pepper plants showing symptoms were tested for tomato spotted wilt orthotospovirus (TSWV) using specific primers targeting the full coat protein gene (CP) through RT-PCR. Plant samples were collected in Denizli region, Türkiye during September 2021. The PCR screening results revealed that 23 samples were infected with TSWV, indicating an infection rate of 29.48%. PCR products were subsequently sequenced bidirectionally, and the obtained sequences were deposited in GenBank under the accession numbers ON323583-84 for pepper, and OQ597214 for tomato. Phylogenetic analysis demonstrated a close relationship between the Turkish-Denizli TSWV isolates and previously reported isolates from tomato and pepper plants in Türkiye (KM407603), Hungary (KJ649612), and Serbia (GU369723). Moreover, in this study, three commercial chemicals and five selected phytochemicals were docked against the TSWV CP to assess their binding energies. The docking results indicate that the tested phytochemicals exhibit promising performance compared to other commercial chemicals. This study represents the first molecular and phylogenetic report on TSWV isolates in pepper and tomato plants in Denizli province, Türkiye. Furthermore, the interaction between TSWV and the selected compounds through in silico docking has been reported for the first time. © Articles by the authors; Licensee UASVM and SHST, Cluj-Napoca, Romania.
