Overexpression of <i>StTCP10</i> Alters Tuber Number and Size in Potato (<i>Solanum tuberosum</i> L.).

ABSTRACT: Potato (Solanum tuberosum L.), cultivated worldwide for its nutrient-rich underground tubers, represents a crucial staple crop whose yield is primarily determined by both tuber number and tuber size. TCP transcription factors, especially TCP containing miR319 binding sites, play pivotal roles in plant growth and development, yet their functions in potato tuber number and size remain largely unexplored. In this study, we systematically identified 32 TCP genes in potato harboring the conserved TCP domain, among which six were predicted to contain binding sites for Stu-miR319. Semi-quantitative experiments revealed that StTCP10 exhibited the highest expression levels in stolons, swollen stolons, and tuber tissues compared to other StTCP genes containing miR319 bind
