Small RNAs (sRNA) play an essential role in the epigenetic modulation of the genome. They are implicated in numerous processes, encompassing factors that mitigate both abiotic and biotic stressors. Notable among these are heat shock proteins (HSP), enzymes involved in reactive oxygen species (ROS) scavenging, and nuclear factor Y (NF-Y). Molecularly, sRNAs are characterized by sequences of approximately 21–23 nucleotides in length. Based on contemporary understandings in plant science, numerous abiotic constraints have the potential to curtail crop yield, growth, and reproductive potential in plants. These constraints exert their deleterious effects by undermining cellular homeostasis, perturbing ionic equilibrium, and impinging upon essential physiological processes. However, evolution has endowed certain plant species with the ability to adapt to elevated thermal conditions through the nuanced regulation of genes and proteins, notably heat shock factors (HSF) and HSP. While there has been an incremental growth in literature concerning microRNA (miRNA) functionality in plants, the emergent targets of miRNA and their intricate relationship with the HSF-HSP complex remain underexplored. In this scholarly review, we delve into the thermal responses of HSF-HSP in both Hordeum vulgare and Arabidopsis thaliana, emphasizing their regulation by miRNA under conditions of heat stress. 2024-01-01T00:00:00Z
