Application of different molecular markers in biotechnology

Aug 2020 | Berna KOCAMAN, Sevim TOY, Sevgi MARAKLI

Several molecular markers have been developed to explore genetic diversity, resistance against biotic/abiotic stress, disease, biomarker and evolutionary relationships in different genomes. These markers could be classified as sequence, hybridisation, PCR and retrotransposon based techniques. In this study, procedure and applications of AFLP (Amplified Fragment Length...

Coatomic refinable modules

Aug 2020 | Burcu NİŞANCI TÜRKMEN, Ergül TÜRKMEN

In this article, we define the concept of (strongly) coatomic refinable modules as a proper generalization of (strongly) refinable modules. It is shown that: (1) every direct summand of a coatomic refinable module is coatomic refinable; (2) over a left max ring a module M is (strongly) coatomic refinable if and only if it is (strongly) refinable; (3) if a coatomic refinable...

An in vivo study on Drosophila melanogaster, Artemia salina, and Daphnia magna: Is activated carbon used as a food additive reliable?

Aug 2020 | Mehmet FİDAN, Arif AYAR

Activated carbon, one of the most important adsorbents used in the industry, is a general definition used to describe carbon adsorbents, which have a large crystal and amorphous structure and wide internal pores. Activated carbon, which has started to be used in many fields in recent years, is observed to be preferred as an important additive in the food industry. This study...

Ferro-chelatase enzyme activity of blue green algae from Yeşilırmak

Aug 2020 | Vahit KONAR, Önder İDİL, Emine ÇELİKOĞLU, et al.

Blue green algae are microscopic photosynthetic bacteria, naturally in ponds, rivers, lakes and streams. Tetra pyrroles can be classified based on the presence, position and substituents of a chelated metal in the pyrrole ring. Heme and chlorophyll, which are the most common tetra pyrolle in nature, are synthesized by blue green algae. Heme is an essential cofactor for virtually...

An easy and reliable method for establishment and maintenance of tissue cultures of Nicotiana tabacum cv TAPM 26

Aug 2020 | Yilmaz KAYA, Fahrul Zaman HUYOP

In vitro regeneration of Nicotiana tabacum was efficiently achieved using growth regulators combination supplemented into semi-solid MS medium using leaves from 1-month-old plant as explants. The growth regulators used were NAA for auxin (0.0, 1.0, 2.0, and 3.0 mgL -1 ) and BAP (0.0, 0.5, 1.0, 2.5, and 5.0 mgL -1 ). The effects of growth regulator combination were assessed based...

Isolation and molecular phylogeny of RFT1 gene from upland rice leaves cultivar

Aug 2020 | Sulaıman MOHAMMED

Rice is a modern short-day plant but equally flower during non-inductive long-day condition due to the possession of second florigen, Rice Flowering Locus T1 (RFT1) . RFT1 is an ortholog of Arabidopsis FT gene which triggers flowering induction under long-day (LD) condition. The gene isolation from Malaysian upland rice cv. Wai that induces flowering were reported. Nucleic acids...

Agriculture History and Policy

Mar 2020 | Abdulgani DEVLET

The ancient Fertile Crescent in particular, is commonly comprehended as the origin of agriculture. The location of Western Asia covers the area of Mesopotamia and the Levant, and is limited by Syrian Desert to the south and the Anatolian Plateau to the north. First of all, a good diagnosis is needed to treat the disease, it is necessary to make a good diagnosis and definition for...

Sperm Storage and Artificial Insemination in Honey Bees

Mar 2020 | Arda Onur ÖZKÖK, Murat SELCUK

To obtain the expected yield from a honeybee colony, queen bee is required to have high egg capacity, the colony is also expected to be resistant to diseases, to have a low tendency for swarming, to be resistant to looting, and to be able to adapt to the climatic conditions of the region. In this context, it is important to protect the pure bee races and to improve them by...

Effects of Grape (Vitis vinifera L.) Seed Oil and St John’s Wort (Hypericum perforatum L.) Extract Supplementation into Diets of Laying Hens at Different Levels on Performance, Egg Quality and Some Blood Parameters

Mar 2020 | Gözde KILINÇ, Mevlüt KARAOĞLU

This study set out to determine the effects of dietary supplementation of grape seed oil and Hypericum perforatum L. extract to the laying hens (Lohmann White, 40 weeks of age) on performance, egg quality and some blood parameters. For this purpose, a total of 336 hens were randomly distributed to the control and other treatment groups, 12 replicates/group with 4 hens/replication...

The effects of concentration based on the absorbance form the ultraviolet–visible (UV-VIS) spectroscopy analysis

Mar 2020 | Jamal ALDABİB, Mohamed EDBEİB

This experiment utilizes the material characterization technique known as UV-Vis spectroscopy. The aim of this research is to study the UV-Vis absorption spectroscopy readout in order to investigate the effect of concentration on absorbance for gold solution and to determine the value of band gap for powder sample (TiO 2 ). The types of TiO 2 specimens can be characterized on a...
