摘要： Potatoes are valued as reliable crops due to their high carbohydrate content and relatively low farming demands. Consequently, significant attention has been directed towards understanding and controlling the life cycle of potato tubers in recent years. Notably, recent studies have identified self-pruning 6A (StSP6A) as a key component of the tuberigen, the mobile signal for tuber formation, produced in leaves and then transported underground to induce tuber formation in potatoes. Recent progress in comprehending the signaling mechanisms that regulate StSP6A by photoperiod and ambient temperature components, its long-distance transport into underground tissue, and its involvement in regulating stolon tuberization has advanced significantly. Consequently, the modulation of StSP6A and other possible tuberigen signals, along with their regulatory pathways, significantly impacts potato domestication and crop yield. This progress highlights the differential regulation of tuberigen signals and their potential functions in promoting tuber formation.
