Genetic Diversity of Eight Domestic Goat Populations Raised in Turkey

The objective of this study was to determine the intra- and intergenetic diversities of eight different goat populations in Turkey including Hair, Angora, Kilis, Yayladag, Shami, Honamli, Saanen, and Alpine. A total of 244 DNA samples were genotyped using 11 microsatellites loci. The genetic differentiation between breeds was considerable as a result of the statistically significant (P < 0.001) pairwise F ST values of each pair of breeds. Exceptionally, F ST values calculated for Honamli and Hair breeds were statistically nonsignificant (P > 0.05). Heterozygosity values ranged between 0.62 and 0.73. According to the structure and assignment test, Angora and Yayladag goats were assigned to the breed they belong to, while other breeds were assigned to two or more different groups. Because this study for the first time presented genetic data on the Yayladag goat, results of structure analysis and assigned test suggest that further analyses are needed using additional and different molecular markers.

Genetic diversity and population structure of wheat in India and Turkey

Genetic diversity assessment plays an important role in plant improvement. It becomes more significant when evaluation is done at different ploidy and geographical origin levels. The present study provides a better understanding of the genetic association of Indian and Turkish hexaploid and tetraploid wheat. The Turkish hexaploid population demonstrated its close association with Indian hexaploid and tetraploid varieties. This confirmed their relatedness within the diverse gene pool. The results revealed in this study can be effectively used by breeders and evolutionary biologists for the development of genetically diverse, promising and healthier wheat varieties.

Comparison of different methods for identification of meat species in meat products

Bulgular: Analizde kullanılan AGID, ELISA ve PZR yöntemlerinde aynı örnekler sığır eti yönünden pozitif bulundu. ELISA sonuçlarına göre üç örneğin (2 salam ve 1 sucuk) sığır eti bakımından negatif olduğu saptandı. PZR sonuçlarına göre ise bu üç örneğinde içinde olduğu toplam 11 farklı örnekte, küçük ruminant (koyun/keçi) kalıntısı tespit edildi. Ayrıca farklı 3 örnekte ise kanatlı (tavuk) kalıntısı tespit edildi. Kullanılan üç yöntemde de tüm örneklerde domuz, at, karnivor (kedi) kalıntısının olmadığı gözlendi.
