Abstract: The potato plant is among the most important and well-documented crops globally due to its role in ensuring human food security. Dormancy and sprouting behaviors of the potato tuber are among the most studied phenomena of its developmental stages. Tuber dormancy and sprouting are complex processes influenced by potato genetic background and environment, but the specific genes and molecular mechanisms controlling tuber dormancy and sprouting are still ill-defined. To develop and use engineered plants in the future, we need to better understand the molecular regulation of various physiological processes such as dormancy, sprouting, tuber growth, and flowering. This review highlight that StZEP, StNCED, StCYP and StSUT4 genes are involved in dormancy. Moreover, Ipt gene plays a major role during the release of dormancy. Sprout growth is regulated by ARF1, STIAA, and STGA20x which controls the endogenous content of IAA and GA. However, the mode of action of the main regulatory genes should be determined. This review's objective was to combine new insights into the most critical genes expressed during potato dormancy and sprouting. The information gathered revealed that organized genetic factors drive both the potato dormancy and sprouting process. The combined assessment of multiple genes is necessary to identify the best candidate genes for genetic engineering. [ABSTRACT FROM AUTHOR]
