Abiotic stress-related miRNAs in Triticeae

Plants have developed very complex mechanisms to overcome various environmental stresses. it has been found that abiotic stresses such as nutritional stress, drought, cold, salinity, heavy metal, oxidative stress regulate the expression of hundreds of genes in transcriptional and post- transcriptional levels in plants. recent studies show that mirnas also play a role in these mechanisms. plant micrornas (mirnas) play an important role in basic processes such as the development and maintenance of genome integrity in response to abiotic and biotic stresses. understanding the complex molecular mechanism regulated by mirnas during abiotic and biotic stresses may offer new approaches to improve plant productivity. this review describes how mirnas under different abiotic stresses play a role in stress tolerance and their effects on target genes. in addition, various down and up regulated plant mirnas have been focused on the response mechanisms to stress. in light of this information, the mirna profile of plants exposed to different environmental stresses will help researchers identify and characterize new mirna targets in future studies.
