Abstract :Plants are sessile organisms affected by changing environment, especially biotic and abiotic stress. Long non-coding RNAs (lncRNAs) became prominent as crucial regulators in diverse biological mechanisms, including developmental processes and stress responses such as salinity. In this study, salinity related lncRNAs were sequenced and analyzed according to homology based on rice and maize lncRNA sequences. After sequencing, 72HASATROOT and 72TARMROOT were identified as 568 bp, additionally, 72HASATSHOOT and 72TARMSHOOT were also 568 bp according to reference sequence which are the member of the natural-antisense lncRNA with 565 bp. Besides, 77HASATROOT and 77TARMROOT were identified as 676 and 644 bp, additionally, 77HASATSHOOT and 77TARMSHOOT were 666 bp according to reference sequence alignment that reference sequence was 667 bp and the sno-lncRNA member. Sequencing studies demonstrated sequence alterations resulted in secondary structure changes which may affect the adaptation of varieties in response to stress. As a conclusion, rapid evolution of lncRNAs may be another force for adaptation to changing environment in plants.
