Türkiye’de Yetişen Lallemantia Fisch. & C.A.Mey. Türlerinin Karyotip Analizleri: Detaylı Karyotip Asimetri Çalışması

Bu çalışma Türkiye’de yetişen Lallemantia Fisch. & C.A.Mey. cinsine ait üç türün [Lallemantia peltata (L.) Fisch. & Mey., Lallemantia iberica (Bieb.) Fisch. & Mey. and Lallemantia canescens (L.) Fisch. & Mey.)] karyolojik analizinin yapılmasını amaçlamıştır. Ayrıca, bu araştırmada çeşitli karyotip asimetrisi ve /AI, CVCL and MC değerleri de hesaplanmıştır. Tohum örnekleri doğal habitatlarından toplanmış ve Feulgen boyama metodu kullanılmıştır. Bu çalışma, Lallemantia türlerinin kromozom sayılarının 2n=14 olduğunu ve median ve submedian sentromer kromozomlara sahip olduklarını bulmuştur. Ve ayrıca, bu çalışma Lallemantia cinsine ait üç türün Stebbbins sınıflandırmasına göre 2A grubunda olduğunu ileri sürmüş ve karyotip analizi ve asimetri değerlerini göstermiştir. Bundan başka, bu çalışma karyotip asimetri değerlerini kullanarak Pearson korelasyonunu ve A1 and A2’yi kullanarak saçılım grafiğini göstermiştir. Çalışmadan elde edilen sonuçlar, farklı literatürler tarafından yapılan karyotip analizlerinin sonuçlarıyla karşılaştırılmış ve lokailtelere göre farklılıklar olabileceği sonucuna ulaşılmıştır.

Karyotype Analysis of Lallemantia Fisch. & C.A.Mey. Species Grown in Turkey: A Detailed Karyotype Asymmetry Study

The study aimed to karyologically analyse three species [(Lallemantia peltata (L.) Fisch. & Mey., Lallemantiaiberica (Bieb.) Fisch. & Mey. and Lallemantia canescens (L.) Fisch. & Mey.)] from Lallemantia Fisch. &C.A.Mey. (Lamiaceae) grown in Turkey. Also, it was calculated various karyotype asymmetry and S/AI, CVCLand MC values in this study. Seed samples were given natural habitats and Feulgen staining method was used. Thestudy showed that the chromosome numbers of Lallemantia species are 2n=14 and that they have median (m) andsubmedian (sm) centromeric chromosomes. The study also demonstrated karyotype analysis and asymmetryvalues and suggested that three species of Lallemantia genus were 2A based on Stebbins classifications.Furthermore, the study showed Pearson correlation using karyotype asymmetry values and a scatter diagram wasformed using A1 and A2. The results obtained from the study were compared with the results of karyotype analysisperformed by different literatures and it was concluded that there may be differences according to locality.
