Ramazan Beyaz
Sainfoin (Fabaceae) is one of the most critical animal forage crops. However, the tolerance of sainfoin is low against to salinity. This study aims to investigate biochemical responses of the shoot and root tissue of sainfoin seedlings to moderate salt stress under in vitro conditions. For this aim, the seed of sainfoin were sown MS medium containing 100 mM NaCl. Antioxidant enzymes (CAT, SOD, APX, and GR), proline and malondialdehyde (MDA) contents were measured in shoot and root tissue of 35-day-old seedlings of sainfoin. A significantly higher constitutive catalase (CAT) and superoxide dismutase (SOD) activity was observed in shoot tissues when compared to root tissues. Overall, salt stress caused significant more enhancement in the activity of antioxidant enzymes (CAT, SOD, APX, and GR) in shoot tissues than root tissue. On the other hand, among the antioxidant enzymes, SOD seems to be more active in both tissues of sainfoin. Interestingly, the activity of GR reduced in both tissue under salt stress. The content of proline and MDA has been increased under salt stress and this increase has been more in the root tissue. This study has revealed biochemical responses to salt stress in different organs of sainfoin.

Ahmet Kınay | Halil Erdem
Kurşun (Pb), belirli eşik konsantrasyonları aştığında insanlar, hayvanlar ve bitkiler için tehlikeli olan bir ağır metaldir. Tütün bünyesinde yüksek konsantrasyonlarda kurşun biriktirebilen bir bitkidir. Kurşun alımında tütün genotipleri arasındaki farklılıklar ve bitkilerin kurşuna verdikleri henüz cevap açıkça belirlenmemiştir. Bu çalışmanın amacı, Pb dozlarının (Pb 0; 0,25; 2,5 ve 10 mg kg-1) iki farklı tütün çeşidinin (Xanthi/2A ve Nail) biyomas (kök ve yeşil aksam) üretimi, Pb konsantrasyonu ve mikro besin konsantrasyonları üzerindeki etkilerini belirlemektir. Kontrollü koşullar altında yetiştirilen tütün çeşitlerine artan Pb dozları ile birlikte temel makro (N, P ve K) ve mikro (Fe ve Zn) besin elementleri verilmiştir. İki farklı tütün çeşidinde biomas üretimi (kök ve yeşil aksam kuru madde verimi), yeşil aksam Pb, Zn, Fe, Mn ve Cu konsantrasyonları belirlenmiştir. Artan dozlarda Pb uygulaması ile çeşitlerin kuru madde verimi önemli ölçüde etkilenmiştir. Kök ve yeşil aksamda ortaya çıkan azalmaya karşın, artan dolarda kurşun uygulamaları ile tütün çeşitlerinin yeşil aksam kurşun konsantrasyonlarında istatiksel olarak önemli artışlara neden olduğu ortaya çıkmıştır. Artan dozlarda Pb uygulaması ile tütün çeşitlerinin yeşil aksam Zn, Fe, Mn ve Cu konsantrasyonlarında istatiksel olarak önemli artış ve azalışlara neden olduğu ortaya çıkmıştır. Sonuç olarak en yüksek kurşun dozunda dahi Nail ve Xanthi/2A tütün çeşitlerinin yeşil aksamında 1,0 mg kg-1’ın altında Pb konsantrasyonuna sahip olduğu ortaya çıkmıştır. Buna rağmen kurşun ile kirlenmiş topraklarda yetişen tütün çeşitleri ile yapılan tütün mamulleri insanlar içim risk teşkil etmektedir.

The improvements on the next generation sequencing or high-trough output technologies allowed the discovery of several unknown viruses in grapevines and also in other plants . The most important new emerging grapevine viruses were identified as Grapevine pinot gris virus (GPGV), Grapevine syrah virus 1 (GSyV-1), Grapevine red blotch-associated virus (GRBaV) and Grapevine roditis leaf discoloration virus (GRLDaV). The aim of the present study was to investigate the occurrence and characterization of these viruses in Tekirdag and Hatay viticulture production areas by PCR and DNA sequencing analyses. Totally 191 and 111 grapevine samples showing both virus-like symptoms and symptomless were collected from Tekirdağ and Hatay provinces, respectively. Among the tested samples GPGV and GSyV-1 were detected in both local and imported cultivars by the infection rate of 43.62 % and 1.04% in Tekirdağ , respectively. In Hatay provice, only GSyV-1 was detected by the infection rate of 0.9 % and all tested samples were negative for GPGV, GRBaV, GRLDaV. RT-PCR results showed that DNA fragments of 411 bp, 302 bp and 618 bp corresponding to the part of the coat protein (CP), movement protein (MP) and the replicase genes of GPGV were successfully amplified in Tekirdağ samples. All PCR products of GPGV were directly sequenced on both strands. All the nucleotide sequences of CP, MP and 5’ UTR and N-terminus of replicase genes shared the highest sequence identity with different GPGV isolates deposited in Genbank

Safiye Selin Köymen | Mağrur Kazak
According to the report of World Health Organization / Food and Drug Administration, probiotics are expressed as, ‘‘live microorganisms that have a positive effect on the health of the host when consumed in sufficient quantities’’. People use probiotics to treat diseases and to promote general health. Probiotic bacteria should adhere to the tooth surface to prevent and slow down the tooth decay and also should join to the microbial dental plaque bacteria. However, probiotic bacteria should damage and compete with the cariogenic bacteria and prevent the growth of bacteria. In addition, probiotic bacteria should be able to reduce the acid production by affecting the carbohydrate metabolism. Probiotic is a new and interesting research topic in oral microbiology and oral diseases. A wide range of epidemiological investigations will demonstrate the different benefits of probiotics on human health.

Susam kepeği endüstriyel bir atık olup günümüzde teknolojik olarak değerlendirilmemekte ya da sınırlı miktarda hayvan yemi olarak besicilere sunulmaktadır. Bu çalışmada, özellikle ülkemizde kavrulmuş susam, tahin ve tahin helvası işletmelerinde yoğun bir girdi olarak kullanılan susamın kuru ve ıslak hat adı verilen susam işleme hatlarından atık olarak açığa çıkan toplam üç farklı susam kepeklerinden protein ve antioksidan özellikli maddeleri geri kazandırma potansiyelleri incelenmiştir. Bu kapsamda, üç farklı noktadan çıkan kepek atıklarından (Kuru hat I, Kuru hat II ve Islak hat II) alkali yöntem ile protein özütlemesi yapılmış ve ayrıca susam kepeklerinden fenolik maddelerin özütlenmesinde %70’lik (v/v) aseton, etanol ve metanolün sulu çözeltilerinin etkileri incelenmiştir. Kuru hat susam kepeğinin ıslak hat kepekten daha düşük protein içeriğine sahip olduğu belirlenmiş; buna karşın kuru hat kepekten daha yüksek protein özütleme verimi elde edilmiştir. Kuru ve ıslak hat susam kepeklerine ait fenolik madde özütlerinin, alkali yöntem ile elde edilen protein özütlerinden daha yüksek toplam fenolik madde içeriğine ve antioksidan kapasite değerlerine (DPPH ve ABTS yöntemleri sonucu) sahip oldukları tespit edilmiştir. Susam kepeğinden fenolik maddelerin özütlenmesinde en etkili çözgenin %70’lik aseton çözeltisi olduğu belirlenmiş; etanol ve metanolün kullanıldığı özütlere ait sonuçlarda istatistiki olarak önemli farklılık bulunmamıştır.

The objective of this study was to determine the relationships between animal welfare scores (AWS) and milk production in dairy cattle. AWS traits on locomotion ability (LA), social interaction (SI), flooring (F), indoor conditions (IC) and stockmanship effect (SE) were scored by a 100 points scale in a total of 51 farms in Samsun region of Turkey. First lactation milk yield (FLMY) records of Brown Swiss and Simmental cows were used as milk production trait. All components were assessed by t-test to determine the effects of the welfare traits on FLMY. The overall mean of AWS was calculated to be 74.05±1.69, and therefore the farms were founded within a “suitable” class. It was estimated moderate correlations among the parameters except for AWS and SI, however, no statistically significant difference was estimated between AWS and FLMY of the cows. SE was revealed the most important factor on AWS of the farms. Finally, routine scoring cattle farms to decide their suitability for animal needs is advised to herd owners for managing rentable populations in the farms.
