Abstract

Potassium nutrition is associated with plants that are more resistant to biotic and abiotic stresses. We investigated metabolic changes in soybean plants grown under four potassium (K+) soil fertilization rates. Untargeted metabolomic analysis revealed that soyasaponins contents are responsive to K+ status in soybean leaves and acts as phytoalexin when chemometrics analysis showed higher levels of DDMP-soyasaponins evidently accumulated in trifoliate leaves severely K+ deficient.
