Environmental stresses, such as drought, salinity, and pathogen attacks, significantly affect
potato growth, development, and yield by disrupting key physiological and biochemical
processes. Plant responses to these stresses are mediated by changes in gene expression,
transcriptional regulation, and the activity of various functional proteins, all of which
contribute to the molecular mechanisms of stress tolerance. Genome editing using the
CRISPR/Cas9 system has been effectively used to enhance the resistance of potato to
environmental stresses and to improve its nutritional value. This article provides a comprehensive review of recent studies retrieved from academic databases focusing on the effects
of various environmental stressors on potato growth, yield, and postharvest storage. It also
examines the influence of these stresses on the production of secondary metabolites and
their associated molecular pathways. Finally, the review highlights advancements in the
application of CRISPR/Cas-based genome editing technologies between 2021 and 2025 to
improve stress tolerance and nutritional traits in potato plants.
