A karyological study on Iberis attica Jord. Brassicaceae

Abstract

In this study, it was determined the chromosome number and karyotype analyses of Iberis attica Jord. This species belongs to the Brassicaceae that is widely distributed in Turkey. The somatic chromosome number was determined as 2n = 14 in I. attica. The basic chromosome number was observed as x = 7. The karyotype formula of this species consists of seven median chromosome pairs. The somatic chromosome length between 1.80-2.63 µm. Total haploid chromosomes length was measured as 14.87 µm. The karyogram and ideogram of this species was illustrated based on centromeric index and put chromosome pairs in the decreasing size order

Iberis attica Jord. Brassicaceae türünde karyolojik bir çalışma

Abstract

Bu çalışmada Iberis attica Jord.’nın kromozom sayısı ve karyotip analizi belirlenmiştir. Bu tür, Türkiye’de geniş yayılışa sahip olan Brassicaceae familyasına aittir. I. attica’ da somatik kromozom sayısı 2n = 14 olarak belirlenmiştir. Temel kromozom sayısı ise x =7 olarak gözlenmiştir. Bu türün karyotip formülü 7 çift median kromozom tipinden oluşmaktadır. Somatik kromozom boy uzunluğu 1.80-2.63 µm arasındadır. Toplam haploid kromozom boy uzunluğu ise 14.87 µm olarak ölçülmüştür. Bu türün karyogram ve idiyogramı sentromerik indeks temel alınarak ve kromozom çiftlerinin büyükten küçüğe sıralanması ile çizilmiştir
