Identification and screening of plant hormone-related genes associated with dormancy release in Prunus persica seeds using transcriptomics and targeted metabolomics.

ABSTRACT: Peach (Prunus persica) seeds exhibit low natural germination rates and prolonged germination periods due to deep dormancy, which severely limits seedling propagation efficiency and industrial scalability. In this study, four treatment groups were established: CK (water), T1 (gibberellin + sodium fluoride), T2 (sodium hypochlorite), and T3 (sodium fluoride), all combined with temperature regulation. Physiological measurements, transcriptomic analysis, and targeted metabolomic analysis were integrated to investigate the dynamic changes during seed dormancy release. Exogenous substance treatments significantly enhanced germination performance, accompanied by distinct fluctuations in endogenous hormone levels, including IAA, GA₃, ABA, and CTK. Analysis of the ABA/GA₃ ratio revealed that the 45
