Abstract As sessile organisms, plants are continuously exposed to heterogeneous and changing environments constantly need adapt their growth strategies. They have evolved complex mechanisms recognize various stress factors, activate appropriate signaling pathways, respond accordingly by reprogramming the expression of multiple genes at transcriptional, post-transcriptional, even epigenome levels tolerate stressful conditions such as drought, high temperature, nutrient deficiency, pathogenic interactions. Apart from protein-coding genes, long non-coding RNAs (lncRNAs) emerged key players in plant adaptation environmental stresses. transcripts larger than 200 nucleotides without potential. Still, they appear regulate a wide range processes, including epigenetic modifications chromatin reorganization, well transcriptional post-transcriptional modulation gene expression, allowing LncRNAs can positively or negatively modulate responses, affecting processes hormone signaling, temperature tolerance, deficiency adaptation. Moreover, also seem play role memory, wherein prior exposure mild enhances ability subsequent conditions. In this review, we summarize contribution lncRNAs biotic abiotic stresses, memory. The evolutionary conservation is discussed provides insights into future research directions field.

Eukaryotic genomes encode thousands of RNA molecules; however, only a minimal fraction is translated into proteins. Among the non-coding elements, long RNAs (lncRNAs) play important roles in diverse biological processes. LncRNAs are associated mainly with regulation expression genome; nonetheless, their study has just scratched surface. This somewhat due to lack widespread conservation at sequence level, addition relatively low and highly tissue-specific patterns, which makes exploration challenging, especially plant where few these molecules have been described completely. Recently published high-quality crop plants, along new computational tools, considered promising resources for studying plants. review briefly summarizes characteristics lncRNAs, presence conservation, different protocols find limitations protocols. Likewise, it describes physiological phenomena. We believe that lncRNAs can help design strategies reduce negative effect biotic abiotic stresses on yield plants and, future, create fruits vegetables improved nutritional content, higher amounts compounds positive effects human health, better organoleptic characteristics, longer postharvest shelf life.
