Özet

This study aimed to research the impact of putrescine against the long terminal repeat (LTR) retrotransposon polymorphisms (Nikita-E2647, Sukkula, Stowaway, WLTR2105 and 5'LTR) induced by salinity stress in Triticum aestivum using inter-retrotransposon amplified polymorphism (IRAP) assay. The results showed that the LTR retrotransposon polymorphisms can be induced by all treated sodium chloride (NaCl) doses (0, 50, 100, 200 and 300 mM NaCl). On the other hand, the LTR retrotransposons polymorphisms were decreased effectively by treatment with putrescine (0, 0.01, 0.1 and 1 mM) together with NaCl. These results suggest that putrescine could effectively inhibit salt-induced LTR retrotransposon polymorphisms, and putrescine positively contributed to salt stress tolerance.
