Özet
Öz: Bu çalısmada, Drosophila melanogaster’in somatik mutasyon ve rekombinasyon testi kullanılarak EMS ile indüklenmis mutant kanat benekleri üzerine bitki büyüme hormonlarının (kinetin, gibberellik asit (GA3) ve indol asetik asit (IAA)) etkisi arastırıldı. GA3, EMS ile indüklenen bütün kanat beneklerini azalttı. Kinetinin 10-3 M konsantrasyonu EMS ile indüklenen ikili beneklerin sayısını azaltırken, 10-4 M konsantrasyonu beneklerin bütün tiplerinin sayısında artısa neden oldu. Aynı konsantrasyonlardaki IAA ise degisken sonuçlar verdi. 10-4 M IAA yalnızca büyük tekli beneklerin sayısını indirgedi. Sonuçlarımız bitki büyüme hormonlarının (özellikle GA3’ün) bio-antimutagen olabilecegini düsündürmektedir.
Abstract: The effect of plant growth hormones (kinetin, gibberellic acid (GA 3) and indole acetic acid (IAA)) on EMS-induced mutant wing spots was studied with the somatic mutation and recombination test (SMART) in Drosophila melanogaster.GA 3 reduced all kinds of EMS-induced spot. While a 10 -3 M concentration of kinetin reduced only the number of EMS-induced twin spots, a 10 -4 M concentration was seen to increase the number of all types of spot. The same concentrations of IAA gave variable results. A 10 -4 M concentration of IAA caused a decrease only in the number of large single spots. Our results confirmed that plant growth hormones, especially GA 3 , can act as a bio-antimutagen.
