Exogenous glutamate modulates carbon-nitrogen metabolism and drives secondary metabolism through hormonal crosstalk in tobacco
● Exogenous glutamate reshapes apoplast–symplast amino acid partitioning. ● Exogenous glutamate promotes root symplastic assimilation and glutamine buildup. ● Glutamine dominates xylem transport after exogenous glutamate treatment. ● Glutamate activates the GABA shunt and nicotine/jasmonate metabolism.
