Genetic diversity of Phleum spp. and identification of genes involved in water stress response / Motiejukų (Phleum spp.) genetinė įvairovė ir atsparumo sausrai genų paieška

Jonavičienė, Kristina 08 May 2012 (has links)
Genetic material of Lithuanian origin varieties, breeding lines and wild ecotypes representing P. pratense, P. bertolonii and P. phleoides species were studied for the most important agro-morphological and feeding value indicators as well as at the genetic level employing different biochemical–molecular markers. The water stress experiment clearly demonstrated the existence of different levels of water stress response in Phleum species, suggesting that P. phleoides might have evolved under conditions of limited water availability. “Blind” mapping by HRM was used successfully to map water stress response genes of timothy in the perennial ryegrass mapping population. In total, 12 putative water stress response genes were mapped in seven perennial ryegrass linkage groups. / Pasitelkus agromorfologinius, kokybės ir biocheminius – molekulinius metodus ištirtos lietuviškos kilmės pašarinių, žemaūgių bei stepinių motiejukų veislės, selekcinės linijos bei laukiniai ekotipai. Fiziologiniai sausros atsparumo tyrimų rezultatai įrodė, kad stepiniai motiejukai turi geriau išvystytą atsparumo sausrai mechanizmą. Pirmą kartą motiejukuose aptikti ekspresuojami atsparumo sausrai kandidatiniai genai HRM metodu sužymėti daugiametės svidrės genolapyje.
