Potato (Solanum tuberosum L.) is one of the major tuber crops which is widely grown in the world. Potato growth and devel?opment as well as yield is negatively afected by heat and drought stress alone, but combined stress has devastating efect. MicroRNAs are group of small RNAs which play vital role in gene regulation at transcriptional and post-transcriptional level by repressing or inhibiting protein expression of corresponding target. Current study aimed to understand the func?tion of miR160a-5p and its infuence on its target gene ARF16 under applied stresses. Potato cultivars tolerant (Unica) and sensitive (Russet Burbank) were tested under drought, heat, and their combination of stresses. The expression of miR160a- 5p was revealed to be higher along with the suppression of corresponding target gene ARF16 gene. Transgenic plants also showed improved physiological, and biochemical traits, with lower accumulation of H2O2 and higher levels of proline solely under drought stress conditions. It was also observed that overexpression of miR160a-5p could alter mechanisms for auxin response factor pathways which enabled transgenic plants to have higher tolerance to abiotic stress conditions. Based on our fndings, transgenic Unica and Russet Burbank plants showed increased tolerance to drought and heat stress as compared to wild-type plants. This study can be helpful in understanding the role of miR160a-5p in improved tolerance to abiotic stresses.
