Claim 1application effectsupports2025Source 1DOI PubMed

Exogenous glycine betaine application and genetic engineering to enhance endogenous glycine betaine biosynthesis have been reported to significantly improve plant tolerance to multiple abiotic stresses.

Claim 2biosynthesis pathwaysupports2025Source 1DOI PubMed

In higher plants, glycine betaine is primarily synthesized by two-step oxidation of choline catalyzed by choline monooxygenase and betaine aldehyde dehydrogenase.

Claim 3mechanistic functionsupports2025Source 1DOI PubMed

Glycine betaine contributes to plant cellular homeostasis by modulating osmotic balance, regulating ion flux, scavenging reactive oxygen species, enhancing antioxidant defenses, and stabilizing proteins and membrane structures.
