This study explores the application of GABA-functionalized silver nanoparticles (GABAAgNPs) in nanopriming, a technique used to improve seed germination, accelerate seedling growth, and enhance plant stress tolerance. GABAAgNPs were characterized using diverse techniques, including UV-Vis, FTIR, XRD, TEM, Zeta potential, and DLS. Scanning electron microscopy (SEM) was also used to analyze the seed coat and fluorescence spectroscopy to map chlorophyll content in seedlings and nanoparticle toxicity. The results revealed the ability of GABAAgNPs to induce pore formation in the seed coat, facilitating water uptake and triggering germination processes. Furthermore, the investigation revealed that GABA undergoes metabolism within plant cells, generating glutamate. This glutamate serves as a precursor for the synthesis of aminolevulinic acid (ALA), which ultimately contributes to chlorophyll production, as evidenced by the increased vigor index and improved chlorophyll fluorescence. This work demonstrates the potential of GABAAgNPs as a novel and promising approach to promote seed germination and enhance plant resilience in sunflowers.
