“…Lipids are structural constituents of cell membranes that play critical roles in plant adaptation to heavy-metal stresses. 15 A previous study showed that Cd stress reduces unsaturated FA contents, and linoleic acid was observed in Cd-sensitive rice varieties. 47 By contrast, in this study, we observed a significant enhancement of C 18 unsaturated FA in the Cd-tolerant genotype NH224 under Cd stress.…”

“…13,14 Furthermore, homeostasis of the endoplasmic reticulum and maintenance of plasma membrane stability is related to Cd resistance. 15 To withstand environmental stresses and adapt to their surroundings in a timely manner, plants have developed adaptive mechanisms that enable them to activate moderate defense responses. 16 These defense mechanisms involve a complex interplay of cytochrome P450 enzyme, glutathione S-transferases, plant hormone signaling, MAPK signaling pathways, and the biosynthesis of secondary metabolites.…”

“…The processes of Cd uptake by root, translocation to shoots via the xylem, redistribution at nodes, and remobilization to seeds through the phloem contribute to Cd accumulation in rice grains. , As the primary step to prevent Cd entry, roots play a crucial role in response to Cd stress and have evolved diverse mechanisms against Cd toxicity, including the production of chelates for cell wall fixation, antioxidant defense system, Cd-repulsion, and compartmentalization. , The root morphology and transport proteins in roots also regulate Cd uptake and xylem loading, which are encoded by genes. , Furthermore, homeostasis of the endoplasmic reticulum and maintenance of plasma membrane stability is related to Cd resistance …”

Cadmium (Cd) pollution reduces rice production and quality, putting food security and human health at risk. We conducted comparative physiology and metabolomic analyses in two indica rice ('NH199' and 'NH224') to elucidate the Cdtolerance mechanism. Cd hampered rice growth, induced oxidative stress, and changed the metabolomics profiling of the root. The biochemical and physiological analysis demonstrated that NH224 exhibited a more potent Cd-tolerance ability than NH199. Cd was primarily distributed in root, and NH224 had a lower Cd translocation factor than NH199 by about 24%. The metabolomic analysis revealed 180 and 177 differentially accumulated metabolites between Cd-stressed seedlings and the controls in NH224 and NH199, respectively. In NH224, amino acids biosynthesis, hormone metabolism, lipids-related metabolism, phenylalanine metabolism, and phenylpropanoid biosynthesis pathways were more active and highly associated with antioxidant defense system, biosynthesis of the cell wall and phytochelatins, and maintenance of plasma membrane stability. These findings provide insights into the metabolic profiles of rice following Cd stress and the screening and breeding of Cd-tolerant rice varieties.
