Tobacco (Nicotiana tabacum) PSY peptides and their potential roles in seed germination, vegetative growth, and leaf senescence under osmotic stress
The dual role of NtPSY peptides-promoting growth under optimal conditions while impairing stress tolerance-highlights their function as signaling molecules balancing growth-stress trade-offs. This mechanism aligns with PSY receptor-mediated pathways reported in Arabidopsis, where ligand binding inhibits stress signaling. The study provides novel insights into PSY peptide dynamics in tobacco and suggests potential applications for optimizing stress resilience in crops.
