ABSTRACT SnRK1 (Sucrose nonfermenting‐related protein kinase 1), a kinase family that is evolutionarily conserved in plants and shares direct homology with yeast SNF1 and mammalian AMPK, is a core regulator of energy sensing. SnRK1 plays diverse roles in several physiological processes in plants, including but not limited to plant metabolism, energy homeostasis, growth, development, response to various biotic and abiotic stresses, and activation of plant defense mechanisms. By participating in various signal transduction and integration pathways, SnRK1 is pivotal for enhancing plant adaptability and yield. This review systematically explores the functions of SnRK1 in carbon and nitrogen metabolism, secondary metabolism, as well as its influence on growth and development, and responses to environmental stress. An in‐depth study of SnRK1 kinase not only helps us to better understand how plants maintain their survival and productivity under the challenges of global climate change and resource constraints, but also provides a theoretical basis and potential targets for operation to improve crop traits, crop yield, and stress tolerance by means of genetic engineering, which is of great theoretical and practical significance for sustainable agricultural development and food security.
