TAILIEUCHUNG - Hormonal factors of anti mutagenesis regulation

The genetic activity of phytohormones (Phs) was studied. The investigation was conducted with 4 plants (Allium fistulosum, Lycopersicon esculentum, Triticum aestivum, and Gossypium hirsutum). The action of Phs on plant genetic processes was evaluated by chromosome aberration testing. | Turk J Biol 33 (2009) 15-20 © TÜBİTAK doi: Hormonal Factors of Anti-Mutagenesis Regulation Mekhtizadeh Emin RZA National Academy of Sciences of Azerbaijan, Genetic Resources Institute, Baku - AZERBAIJAN Received: Abstract: The genetic activity of phytohormones (Phs) was studied. The investigation was conducted with 4 plants (Allium fistulosum, Lycopersicon esculentum, Triticum aestivum, and Gossypium hirsutum). The action of Phs on plant genetic processes was evaluated by chromosome aberration testing. It was observed that the exogenic Phs exerted a stabilizing effect on spontaneous plant mutagenesis. The use of Phs before and after the action of mutagenic factors contributed to an increase in the anti-mutational or reparative function of the plants’ genes. It was observed that the Phs exhibited genoprotective or reparative activity. The absence of clearly expressed dependence of these effects on Ph dose was recorded. Key Words: Phytohormones, chromosome aberrations, antimutagenesis Antimutasyonel Düzenlemenin Hormonel Faktörleri Özet: Bitkisel hormonların (Ph) genetic aktivitesi çalışılmıştır. Araştırmalar değişik bitkisel objeler üzerine yoğunlaşmıştır. Bu hormonal preperatların genetik süreçler üzerine etkisi kromozom anarmallikleri testi ile değerlendirilmiştir. Ekzojenik bitkisel hormonların kendiliğinden mutasyon oluşumunda dengeleyici etkiye sahip olduğu tespit edilmiştir. Mutajenik faktörlerin etkisinden önce veya sonra Ph kullanımının genlerin antimutasyonel veya onarıcı fonksiyonunu artırıcı etki yarattığı bulunmuştur. Bitkisel hormonların, geni koruyucu veya tamir edici aktivite sergilediği gösterilmiştir. Ph dozunda bu etkilerin açık bağımlılığının olmadığı belirtilmiştir. Anahtar Sözcükler: Bitkisel hormon, kromozom aberasyon, antimutagenesis Introduction Anti-mutagenesis is a vitally important manifestation of the protective-restorative function of biological systems on the genetic level.
