The phytohormone auxin plays a pivotal role in the differentiation and development of fruit tree branches. This study synthesizes recent advances in understanding the mechanisms of auxin signal transduction and its impact on branch differentiation. Auxin's influence on plant growth and development is mediated through complex signaling pathways involving auxin response factors (ARFs) and Aux/IAA proteins, which regulate gene expression and cellular responses. The interaction between auxin and other phytohormones, such as gibberellic acid (GA), further modulates fruit development and branch differentiation. This review highlights the molecular and genetic evidence supporting the role of auxin in these processes, emphasizing the importance of auxin signaling in the regulation of cell division, expansion, and differentiation in fruit trees. The findings underscore the complexity of auxin-mediated responses and the potential for manipulating auxin pathways to improve fruit tree growth and productivity.
