According to the studies conducted on different plant species, about 90% of the entire genome of a plant is transcribed as RNA. However, only 1-2% of the transcribed genome is protein-coding RNAs which their transcription would end up in in, at least, a protein peptide. Non-coding RNAs are RNA molecules from which no protein is synthesized cannot be translated. Long non-coding RNAs (LncRNAs) are also a group of such non-coding RNAs having a length of about 200 nucleotides. different studies have verfied that LncRNAs are widely diverse in both type and function. Accordingly, sense and antisense, intronic, intergenic, bidirectional, and enhancer LncRNAs are some known altered type of LncRNAs. Long non-coding RNAa primarily interact with messenger RNAs (mRNA), DNA, proteins, and small RNAs (e.g. MicroRNAs, miRNA and siRNA) making them an important agent in gene expression procces at epigenetic, transcription, post-Transcription, translation and post-translation levels. there are also some studies verfying the involvment of such RNAs in regulatation of the time and quantity of expression in response to various conditions. In addition, this large group of RNAs has important roles in biological processes such as chromatin rearrangement, transcription activation and promoter settings, interference with strcuture arrangment of transcriptional productions, and the mRNA to protein translatation proccess. Among the biological effects of long non-coding RNAs, their essential role in phenotyping functions such as growth and development, response to biotic and abiotic stresses (environmental stresses), regulation of cell differentiation and cell cycle can be mentioned. Due to the great importance of non-coding RNAs, especially LncRNAs, in this review article we try to investigate the types and mechanisms of LncRNA functions at different epigenetic, transcriptional, post-transcriptional, translational and post-transcriptional levels. Correspondingly, the relationship between LncRNAs and the response of crops to changes in environmental conditions and their interactive role on factors and proteins involved in the such biological activities in crops are investigated. It has been verified that there are less published articles available related to the role and function of LncRNAsin biological systems of crops, especially cereal.
